Chapter 1 Installation
This chapter introduces the installation of Liebert APM modular UPS, including preliminary checks, location,
positioning, cable connection and installation drawings.
1.1 Introduction
This chapter describes the requirements that must be taken into account when planning the positioning and cabling of
the UPS.
This chapter is a guide to general procedures and practices that should be observed by the installing engineer. The
particular conditions of each site will determine the applicability of such procedures.
Warning: professional installation required
1. Do not apply electrical power to the UPS equipment before being authorised to do so by the commissioning engineer.
2. The UPS shall be installed by a qualified engineer in accordance with the information contained in this manual. All the
equipment not referred to in this manual is shipped with details of its own mechanical and electrical installation information.
Note: 3-phase, 5-wire input supply required
The standard UPS is suitable for connection to 3-phase, 5-wire (A, B, C, N, PE) TN, TT and IT AC power distribution systems
(IEC60364-3).
Warning: battery hazards
Special care should be taken when working with the batteries. When connected together, the battery terminal voltage will exceed
400Vdc and is potentially lethal.
Eye protection should be worn to prevent injury from accidental electrical arcs.
z
Remove rings, watches and all other metal objects.
z
Use only tools with insulated handles.
z
Wear rubber gloves.
z
If a battery leaks electrolyte or is otherwise physically damaged, it must be replaced, stored in a container resistant to
z
sulfuric acid and disposed of in accordance with local regulations.
If electrolyte comes into contact with the skin, the affected area should be washed immediately with water.
z
1.2 Preliminary Checks
Before installing the UPS, please carry out the following preliminary checks:
1. Visually examine the UPS rack for any transit damage, both internally and externally. Report any damage to the
shipper immediately.
2. Verify that the correct UPS is being installed. The UPS has an identification tag on the back of the front door
reporting the model, capacity and main parameters of the UPS.
1.3 Location
1.3.1 Power Distribution Room
The UPS is intended for indoor installation and should be located in an environment with clean air and with adequate
ventilation to keep the ambient temperature within the specified operating range.
The UPS is air-cooled with the aid of internal fans. Cold air enters the UPS through the ventilation grilles at the front
of the cabinet and hot air is released through the grilles at the back. Do not cover the ventilation openings.
Liebert APM Modular UPS User & Installation Manual
2
Chapter 1 Installation
If necessary, install a system of room extractor fans to avoid room temperature build-up. Optional air filters are
available if the UPS is to operate in a dusty environment.
Note: The UPS is suitable for mounting on concrete or other non-combustible surface only.
1.3.2 Battery Room
The batteries will generate small amount of hydrogen and oxygen at the end of battery charge. Therefore, make sure
that the new air ventilation amount in the battery room meets the EN50272-2001 requirement.
Batteries should be mounted in an environment where the temperature is consistent and even over the whole battery.
Temperature is a major factor in determining the battery life and capacity. Typical battery manufacturer performance
data are quoted for an operating temperature of 20°C. Operating above 20°C will reduce the battery life while
operation below 20°C will reduce the battery capacity. Provided that the average battery operating temperature
increases from 20°C to 30°C, the battery life will be reduced by 50%; provided that the average battery operating
temperature is above 40°C, the battery life will be reduced by an exponential multiple. In a normal installation the
battery temperature is maintained between 15°C and 25°C. Keep batteries away from main heat sources and main
air inlets.
When using external batteries, the battery protection device (e.g., fuses or circuit breakers) must be mounted as
close as possible to the batteries and connecting cables should be as short as possible.
1.3.3 Storage
Should the UPS not be installed immediately, it must be stored in a room for protection against excessive humidity
and heat sources. The batteries should be stored in a dry, cool environment with adequate ventilation, at temperature
ranging from 20°C to 25°C at best.
Warning: During storage, periodically charge the battery according to the battery user manuals. In charging process,
temporarily connect the UPS to mains and activate it for the time required for recharging the batteries.
1.4 Positioning
Jacking feet are provided at the bottom of the UPS cabinet to prevent the UPS from moving once it has been placed
to its final position. For optimal design life, the place chosen must offer:
z easy connection
z enough space to easily work on the UPS
z sufficient air exchange to dispel heat produced by UPS
z protection against atmospheric agents
z protection against excessive humidity and high heat sources
z protection against dust
z compliance with the current fire prevention requirements
z For VRLA (Valve Regulated Lead Acid) batteries the operating environment temperature is kept between 20°C
and 25°C. VRLA batteries are at maximum efficiency in this temperature range (see Table 6-2)

Chapter 1 Installation
1.4.3 Clearances
The UPS has no ventilation grilles at either side; therefore, no clearance is required at either side.
To enable routine tightening of power terminations within the UPS, in addition to meeting any local regulations, it is
recommended to provide adequate clearance in the front and at the back of the cabinet for unimpeded passage of
personnel with the doors fully opened for accessing cable termination. Refer to Figure 1-15 for the positioning of the
cabinet. It is recommended to have at least 150mm of rear clearance for ventilation purposes.
1.4.4 Front Access And Rear Access
The component layout of the UPS supports front access and minimal rear access in UPS service, diagnosis and
repair, thus reducing the space requirement for side access.
1.4.5 Final Positioning
Warning
Casters are strong enough for movement across even surfaces only. Caster failure could occur in movement across uneven
surfaces.
When the UPS has been finally positioned, ensure the adjustable feet are set so that the UPS will remain stationary
and stable.
1.4.6 Installing Power Modules And Output Distribution Modules (Optional)
The installation positions of the power modules and output distribution modules are shown in Figure 1-1. Please
install the power modules and output distribution modules from bottom to top, so as to ensure cabinet’s stability.

Operation
Chapter 2 Operation
This chapter introduces the basic knowledge of UPS operation, including the operating theory, operation mode,
battery management and battery protection of the UPS.
Warning: hazardous mains and battery voltage present behind covers
1. No user-serviceable parts are located behind covers that require a tool for their removal.
2. Only qualified service personnel are authorised to remove such covers.
2.1 Brief Introduction
The UPS provides continuous, high-quality AC power to your critical equipment, such as telecommunications and
data processing equipment. The UPS supplies power that is free of the disturbances and variations in voltage and
frequency common to mains power, which is subject to brownouts, blackouts, surges and sags.
The UPS uses the latest in high frequency, double-conversion pulse width modulation (PWM) technology and fully
digital control (DSP) technology to enhance its reliability and increase the ease of use.
2.1.1 Operating Theory
As shown in Figure 2-1, the AC mains source is converted by the rectifiers into DC power. The inverters convert that
DC power from the rectifiers or the DC power from the batteries into AC power, and provide the AC power for the load
through the output distribution modules. The batteries power the load through the inverters in the event of a power
failure. When the inverters are faulty or turned off, the mains source can also power the load through the static
bypass.
If maintenance or repair of the UPS is necessary, the load can be transferred without power interruption to the
maintenance bypass.

2.1.2 Static Switch
The circuit block labeled static switch in Figure 2-1 contains an electronically controlled switching circuit that enables
the load to be connected to either the inverter output or to a bypass power source through the static bypass line.
During normal system operation, the load is connected to the inverters; but in the event of a UPS overload or inverter
failure, the load is automatically transferred to the static bypass line.
Liebert APM Modular UPS User & Installation Manual
Chapter 2
Operation
17
During normal operating conditions, the inverter output and bypass supply must be fully synchronized so as to
achieve a clean (no-break) load transfer between the inverter output and static bypass line. The synchronization
between the inverter output and static bypass is achieved through the inverter control electronics, which make the
inverter frequency track that of the static bypass supply, provided that the bypass remains within an acceptable
frequency window.
A manually controlled, maintenance bypass supply is incorporated into the UPS design. It enables the critical load to
be powered from the maintenance bypass supply while the UPS is shut down for routine maintenance and repair.
Note
When the UPS is operating in bypass mode or on maintenance bypass, the connected equipment is not protected from power
failures or surges and sags.
2.2 Operation Mode
The UPS is an on-line, double-conversion, reverse-transfer UPS that permits operation in these modes:
z Normal mode
z Battery mode
z Auto-restart mode
z Bypass mode
z Maintenance bypass mode (manual bypass)
z ECO mode
2.2.1 Normal Mode
The UPS rectifiers derive power from the AC mains input source and supply DC power to the inverters, which
continuously supply the AC load. Simultaneously, the charger, which derives power from the rectifiers, float or boost
charges the associated backup battery of the UPS.
2.2.2 Battery Mode
The UPS is operating in battery mode when the battery is supplying backup power to the load through the inverters.
Upon mains failure, the UPS automatically transfers to battery mode without power interruption to the load. Upon
restoration of the AC mains, the UPS automatically transfers back to normal mode without the necessity of user
intervention, without power interruption to the load.
Note: Battery start function is available for switching the UPS on into Battery (charged) mode directly during mains
failure. Thus, the battery power can be used independently to increase the UPS utility.
2.2.3 Automatic Restart Mode
The battery becomes exhausted following an extended AC mains failure. The inverters shut down when the battery
reaches the EOD voltage. The UPS can be programmed to automatic restart after EOD after a set variable delay time.
This mode and any delay time are programmed by the commissioning engineer.
During the delay time before automatic restart, the UPS charges the battery so as to avoid power interruption to load
in case of a following power failure.
In case the UPS is not programmed to automatic restart, you can use the FAULT CLEAR key to manually start the
UPS.
2.2.4 Bypass Mode
During normal mode operation, if the inverters fail, are overloaded or turned off, the static switch will perform a
transfer of the load from the inverters to the bypass source, with no interruption in power to the load. Should the
inverters be asynchronous with the bypass, the static switch will perform a transfer of the load from the inverters to
the bypass, with interruption in power to the load. This is to avoid paralleling of unsynchronized AC sources. This
Liebert APM Modular UPS User & Installation Manual
18
Chapter 2
Operation
interruption is programmable but typically set to be less than 3/4 of an electrical cycle, for example, less than 15ms
(50Hz) or less than 12.5ms (60Hz).
2.2.5 Maintenance Bypass Mode
If UPS maintenance or repaired is needed, you may use the manual maintenance bypass switch to transfer to the
load to the maintenance bypass, with no interruption in power to the load.
Warning: risk after load transfer to maintenance bypass
After the UPS is transferred to maintenance bypass, the power modules and bypass module are inoperative and the LCD has no
display, only the green indicator of the input surege protective device (SPD) shows the UPS has mains input, but the output
terminals corresponding to closed output distribution switches and the neutral bars are energized.
2.2.6 ECO Mode
IF economical (ECO) mode is selected, the double-conversion UPS operation is inhibited at most times for the
purpose of saving energy. In this mode of operation, the bypass is the preferred source, and only when the voltage
and frequency of the bypass supply are outside specifications will the load be transferred to the inverters. This
transfer takes place with an interruption of less than 3/4 of an electrical cycle, for example, less than 15ms (50Hz) or
less than 12.5ms (60Hz).
2.3 Battery Management
2.3.1 Normal Function
The following functions are configured by the commissioning engineer through dedicated configuration software.
1. Constant current boost charge
The charge current can be set.
2. Constant voltage boost charge
The boost charge voltage can be set as required by the type of battery.
For valve regulated lead acid (VRLA) batteries, the maximum boost charge voltage should not exceed 2.4V/cell.
3. Float charge
The float charge voltage can be set as required by the type of battery.
For VRLA batteries, the float charge voltage should be between 2.2V and 2.3V.
4. Float charge temperature compensation (optional)
The temperature compensation coefficient can be as required by the type of battery.
5. EOD protection
When the battery voltage drops to the EOD voltage, the battery converter will shut down automatically and the battery
is isolated to avoid further battery discharge. The EOD voltage is settable from 1.6V/cell to 1.75V/cell (VRLA) or
0.9V/cell to 1.1V/cell (NiCd).
6. Battery low warning time
The setting range is between 3 minutes and 60 minutes. The default setting is 5 minutes.
Liebert APM Modular UPS User & Installation Manual
Chapter 2
Operation
19
2.3.2 Advanced Function——Battery Self-Test And Self-Service
At periodic intervals 20% of the rated capacity of the battery will be discharged automatically. The minimum amount of
load must exceed 20% of the nominal rating of the UPS. If the load is less than 20%, auto-discharge cannot be
executed. The periodic interval can be set from 30 days to 360 days. The periodic testing can also be inhibited.
Conditions: Battery float charge for at least 5 hours, load 20% ~ 100% of rated UPS capacity.
Trigger: Manually through the Battery maintenance test command on LCD, or automatically.
Battery self-test interval: 30 days ~ 360 days (default setting: 60 days).
2.4 Battery Protection
The following functions are configured by the commissioning engineer through dedicated configuration software.
Battery low warning
The battery low warning occurs before the EOD. After this warning, the battery should have the capacity for 3
remaining minutes discharging at full load. The time is settable from 3 minutes to 60 minutes.
Battery EOD protection
If the battery voltage is lower than the EOD voltage, the battery converter will shut down. The EOD voltage is settable
from 1.6V/cell to 1.75V/cell (VRLA) or 0.9V/cell to 1.1V/cell (NiCd).
Battery circuit breaker (BCB) open warning
This warning occurs when the BCB opens. The battery is connected to the UPS through the BCB, which is manually
closed and electronically tripped by the UPS control circuits.

Bypass Mode to transfer the UPS from normal mode to maintenance bypass mode.
To completely isolate the UPS from the AC supplies, open the external power input isolator.
3.5 Emergency Shutdown Procedures
The Emergency Power Off (EPO) switch on the UPS operator control and display panel is designed to switch off the
UPS in emergency conditions, for example, fire, flood, and so on. The system will turn off the rectifiers, inverters and
stop powering the load immediately (including the inverters and bypass), and the battery stops charging or
discharging.
If the mains input is present, the UPS control circuit will remain active; however, the output will be turned off. To
remove all power from the UPS, the UPS input switch should be opened.
3.6 UPS Reset Procedures
After UPS shutdown due to an EPO action, inverter over temperature or overload, battery overvoltage, excessive

The mains voltage is outside specifications and results in rectifier shutdown. Check the rectifier
input phase voltage
Mains undervoltage
Mains voltage is under-voltage with derated load. Check the rectifier input line voltage
Mains freq. abnormal
The mains frequency is outside specifications and results in rectifier shutdown. Check the rectifier
input frequency
Rectifier fault
Rectifiers detected faulty, rectifiers shut down, battery discharges
Rectifier overtemp.
The heatsink temperature is too high and results in rectifier stop. The UPS can recover
automatically. Check the environment and ventilation
Charger fault
The voltage of the battery charger is too high
Control power 1 fail
The UPS is operating but the control power is abnormal or not available
Mains phase reversed
The AC input phase rotation is reversed
Rectifier overcurrent
The rectifiers are overloaded
Soft start fail
The rectifiers could not start due to low DC bus voltage
Bypass unable to trace
This alarm is triggered by an inverter software routine when the amplitude or frequency of bypass
voltage is outside specifications. The amplitude threshold is fixed for ±10% rating. This alarm
automatically resets once the bypass voltage goes normal.
1. First verify that the bypass voltage and frequency displayed on the LCD are within the selected
ranges. Note that here the rated voltage and frequency are specified by Output voltage level and
Output frequency level respectively.
2. If the displayed voltage is believed to be abnormal, then verify the bypass voltage and
frequency presented to the UPS. Check the external supply if it is found faulty
Bypass abnormal
This alarm is triggered by an inverter software routine when the amplitude or frequency of bypass
voltage exceeds the limit. The amplitude threshold is fixed for ±10% rating. This alarm
automatically resets once the bypass voltage goes normal.
1. First check if there are some relevant alarms such as Bypass phase reverse and Mains neutral
lost. If they appear, solve them first.
2. Then verify that the bypass voltage and frequency displayed on the LCD are within the bypass
limits. Note that here the rated voltage and frequency are specified by Output voltage level and
Output frequency level respectively.
3. If the displayed voltage is believed to be abnormal, then measure the bypass voltage and
frequency presented to the UPS. If the bypass voltage and frequency are abnormal, check the
external bypass supply.
4. If the mains is likely to trigger this alarm frequently, the bypass limits can be changed a little
larger through the configuration software according to the user’s agreement

Explanation
This alarm is triggered by an inverter software routine when the inverter and bypass waveforms
are misaligned by more than six degrees in phase. The amplitude threshold is fixed for ±10%
rating. This alarm resets automatically once the condition is no longer true.
1. First check if the alarm Bypass unable to trace or Bypass abnormal occurs. If so, solve it first.
2. Verify the waveform of the bypass voltage. If it is too distorted, ask the customer to verify and
seek any possible measurements
Inverter fault
Inverter output voltage outside specifications. Load transfers to bypass
Inverter overtemp.
The temperature of the inverter heatsink is too high and reusults in inverter stop. This alarm is
triggered by the signal from a temperature monitoring thermostat on the inverter bridge heatsink.
The UPS will recover automatically after a five minute delay from the disappearance of the
overtemperature signal.
If the overtemperature condition is true, then check for:
1. high ambient temperature.
2. obstructed cooling airway.
3. any fan failure.
4. prolonged inverter overload
Fan fault
At least one of the cooling fans failed
Main STS fail
At least one of the static switches at the inverter side is open or shorted. This fault is locked until
power off
Bypass STS fail
At least one of the static switches at the bypass side is open or shorted. This fault is locked until
power off
Operation invalid
This record is registered following an incorrect operation
Output fuse fail
At least one of the inverter output fuses is blown. The inverters shut down, and the load transfers
to bypass
Control power 2 fail
The UPS is operating but the redundant control power is abnormal or not available
Unit over load
The UPS is confirmed to be overload when the load arises above 105% nominal rating. The alarm
automatically resets once the overload condition is removed.
1. Confirm that the alarm is true by checking the load percent indicated on the LCD to determine
which phase is overloaded.
2. If the alarm is true, measure the actual output current to verify that the indications are valid.
Disconnect uncessary load and ensure the safety
Byp. abnormal shutdown
Both bypass and inverter voltages are abnormal, and the load power is interrupted
Inverter over current
Overcurrent of inverter pulse width modulation module
Bypass phase reverse
The phase rotation of the bypass voltage is reverwed. Normally, phase B lags 120 degrees behind
phase A, and phase C lags 120 degrees behind phase B.
Check that the phase rotation of the UPS bypass supply is correct, and rectify it if it is found to be
in error
Load impact transfer
A transfer to bypass occurred due to a large step load. The UPS should recover automatically.
Turn on connected equipment in sequential order to reduce the step loading of the inverters
Transfer time-out
The load remains on bypass power due to excessive number of transfers that occurred within the
last hour. The UPS will recover automatically and will transfer the load back to inverter power
within an hour
DC bus abnormal
The DC bus voltage is abnormal and results in inverter shutdown. The load transfers to bypass
Parallel board fault
Parallel board is faulty. This may result in UPS transfer to bypass
DC bus over voltage
Rectifiers, inverters and battery converter were shutdown because the DC bus voltage is too high.
Check whether there is a fault at the rectifier side. If no, then check whether overload occurs.
Restart the inverters after resetting the fault

Note :
1. In the case the battery is configured for independent wiring for positive group and negative group respectively (that is, lead four
cables from battery terminals), for the UPS, due to the limitation of the rated current, it is recommended to use a 4P DC
moulded-case circuit breaker (MCCB) (DC rated voltage of the breaker meeting 1-pole 250Vdc, 2-pole 500Vdc, 3-pole 750Vdc,
rated breaking capacity limit being 35kA) or two 2P DC MCCBs (DC rated voltage of single breaker meeting 1-pole 250Vdc,
2-pole 500Vdc, rated breaking capacity limit being 35kA). Connections between the battery, breaker and UPS are shown in
Figure 1.
2. In the case the battery is configured for center tap wiring (that is, lead three cables from battery terminals), it is recommended
to use a 4P DC MCCB, with DC rated voltage of the breaker meeting 1-pole 250Vdc, 2-pole 500Vdc, 3-pole 750Vdc, and rated
breaking capacity limit being 35kA. Connections between the battery, breaker and UPS are shown in Figure 2
