Installation and operating instructions
1. Safety
■
Never allow an exposed flame or spark
near the batteries, particularly while
charging.
■
Never smoke while performing any
operation on the battery.
■
For protection, wear rubber gloves,
long sleeves, and appropriate splash
goggles or face shield.
■
■
The electrolyte is harmful to skin and
eyes. In the event of contact with skin
or eyes, wash immediately with plenty
of water. If eyes are affected, flush
with water, and obtain immediate
medical attention.
■
Tel.X batteries may be stored for up to
one year, without special maintenance.
■
If you fully charge the battery
(according to chapter 6.6), do not store
the batteries for more than 2 months.
5. Preparation for transportation
■
■
■
Remove all rings, watches and other
items with metal parts before working
on the battery.
Make use of original packing cases if
possible. Otherwise protect the batteries
from being damaged and short-circuited.
Transport batteries upright and secured
to prevent tipping.
For transportation over public roads,
each box or pallet must carry a
"hazardous material" label and any
other indication required by local
transport authorities.
■
Use insulated tools.
6. Installation
■
Avoid static electricity and take
measures for protection against
electric shocks.
6.1. General
■
Discharge any possible static electricity
from clothing and/or tools by touching
an earth-connected part "ground"
before working on the battery.
Only trained and certified personnel should
assemble and install Tel.X battery strings.
■
Local regulations related to battery
compartment ventilation (e.g. Telcordia
GR-487-CORE) should be carefully
observed. Saft will not be responsible for
the non-observance of these regulations.
■
Refer to Saft's “Tel.X batteries for telecom
networks - Installation and operation
manual” for complete instructions.
■
Batteries can be charged according to
“In Service Charging” prior to installation.
See chapter 6.6.
■
In case of abnormal events or operating
outside recommended procedures,
measuring the cell Open Circuit Voltage
(OCV) is recommended to check for
normal cell condition before installation.
See paragraph “Troubleshooting and
abnormal operation”.
6.2. Operating environment
■
Tel.X batteries are shipped filled with
electrolyte. A connection kit should also be
included.
Make sure all items are received by
checking the material list included on
each string layout sheet.
Do not top up batteries with water
before, during or after initial installation.
■
3. Unpacking and inspection
■
■
Before installation, measure the OCV of
each battery module and note the values.
The sum of all modules will later be used
to compare with battery string voltage
once assembled.
■
Where applicable, place trays in position
to allow installation with battery modules.
■
Temporarily position the battery modules
in final position in accordance with the
provided layout diagram.
Make sure to orient the positive and
negative terminals correctly.
■
Use only the accessory kit parts provided.
■
When a string barcode label is used,
orient the module that has the affixed
label so it can be accessed in its final
position in the application.
■
When installing a cable, torque the
terminal bolts to 10 ± 1 N.m
(96 ± 9 in.lbs).
■
Apply generous amounts of NoOx,
supplied with the accessory kit,
to all terminal connections made before
and after applying torque.
■
For tight spaces and to use a front
accessible connection, make sure to
install all back cable connections, first,
while blocs are staged outside. To
prevent inadvertent short circuit, make
sure the loose cable end is insulated.
■
The modules can then be slid into place
(in their trays if provided) and all front
connections, cabled from the back, can
subsequently be made.
Tel.X batteries are delivered filled with
electrolyte.
2. Important recommendations
■
The step by step procedures will vary with
application and layout, but the following
should be observed:
For tight spaces and to use a front
accessible connection, make sure to
install all back cable connections, first,
while blocks are staged outside.
To prevent, inadvertent short circuit,
make sure the loose cable end is insulated.
6.3. Recommended tools
The following tools will facilitate installation:
■
Insulated 10 mm socket
■
■
Insulated torque wrench capable
of 10 ± 1 N.m (96 ± 9 in.lbs)
Do not at this stage connect the
system’s power cables.
■
■
Multi meter (VDC)
4. Storage
■
■
Store the batteries in standard
warehouse conditions.
Crimper, 6 AWG, non-insulated lug
(optional)
Connect each battery module using the
accessory kit parts in accordance with
the string layout diagram.
■
After completing terminal connections
and NoOx application, make sure to install
the battery top covers.
■
Battery module handles should remain
in place unless it is obstructing module
placement or connection.
In that case remove them.
■
■
■
Check for damage or electrolyte spillage.
Report any abnormalities to the shipping
company as well as to Saft.
Do not store in direct sunlight or expose
to excessive heat.
Store the batteries in a temperature range
of – 20°C to + 35°C (– 4°F to + 95°F).
Heat shrink gun (optional)
6.4. String assembly
Battery configurations vary depending on
the application. A battery string layout is
provided with each string.

■
Use lugs and sealable heat shrink
provided in the installation kit, when
necessary, for connecting power cables
to the battery terminals.
■
Make sure that the cables are properly
secured and supported.
■
Measure the battery string overall
voltage and compare this with the sum of
all the module OCV’s measured previously.
If values show a discrepancy of 1.0 V or
more, verify the polarity, position and
connection of each module. Reassemble as required.
■
■
■
■
Temperature compensated voltage
control is not recommended.
Disengage temperature compensation
circuit if activated.
Make sure the output of the rectifier is
adjusted between 1.43 to 1.45 VPC; i.e,
the DC bus voltage should be between
54.4 to 55.1 VDC for 38 cells.
Note the polarity of the battery terminals
and verify the polarity of the power
cables before connecting these to the
battery. Look for polarity markings.
DO NOT color match.
Using standard practice and rectifier
manufacturers recommendations as
a guideline, connect the power cables
to the string terminals and secure
hardware: M6 Terminal Torque
10 ± 1 N·m (96 ± 9 in·lbs).
Constant voltage charging is
recommended and should be done
at 1.43 to 1.45 VPC per cell
(54.4 to 55.1 VDC per 38 cell string).
■ In order to re-charge fully in 24 hours,
the minimum current available for each
battery string should be C8/10.
See Table A for values.
■ Temperature compensated voltage control
is not recommended. Check with rectifier
manufacturer for instructions.
■ In case we need to check the IEC
capacity (IEC 60623) the following
procedure must be applied:
■
■
Measure rectifier output voltage and
make sure it is adjusted correctly.
See paragraph “In Service Charging”.
■
Re-torquing the terminal bolts is not
recommended. The hardware is
constructed from nickel plated steel
and stainless steel which requires no
torquing maintenance.
7.4. Floating current monitoring
■
• Make sure that the string is discharged
fully and each cell is at the same SOC.

Gain access to the cell terminals by
removing the battery top covers.
Set aside for re-use.
■
Using a DMW measure each cell and
check that each is greater than or equal
to 1.10 VPC per cell.
■
If a cell is below 1.10 VDC per cell,
set the battery module aside and call
Saft for further instructions.
9. Removal and recycling
■
Make sure appropriate packing materials
are available.
■
Make sure each cell cap is installed
to prevent spillage.
■
All local laws and regulations must be
respected when removing, transporting
and storing used batteries.
■
Contact your local Saft representative
for instructions on recycling.
7.2. Cleaning
■
Apply approved corrosion preventative
compound on string terminals.
■
If a battery must be connected to a live

When the battery is ageing, it is
advisable to check the float charging
current. The battery requires action
if the float current is higher than
5 mA/Ah when charging at 1.43 V/cell.
See Table A for values.
A current clamp with an accuracy
of ± 0.025 Amps is a way to measure
the floating charge.
• Charge at constant voltage with a
maximum voltage set point of 1.65 V
per cell and current limit of C5/5A
as mentioned in the table B:
• Maximum 30 minute pause is allowed.
