The protective cover protects the front panel, particularly the setting
section, against dust, dirt, and water drip. It also prevents the set values from being altered due to accidental contact with the setting
keys.

Installation
■ Connections
Input
Output
Connect a thermocouple, the [email protected] Thermistor or platinum
resistance thermometer to the E5C2 as shown in the following illustration.
If the load circuit is a heating control system, be sure to connect the
load to terminals 4 and 5. If the load circuit is a cooling control system, be sure to connect the load to terminals 4 and 6. If the heating
control system is connected to terminals 4 and 6 or the cooling control system is connected to terminals 4 and 5, the temperature of the
heating control system or cooling control system will be abnormal
and a serious accident may result.
Platinum resistance
thermometer input
Relay output
If the E5C2 is in frequent operation, such as proportional operation,
add an appropriate external relay to the E5C2 by considering the
capacity of the load and the life of the relay.

Power Supply
Thermistor input
Power supply
100/110, 200/220,
110/120, 220/240 VAC
50/60 Hz
If a single power supply is used for the E5C2 and the load, the supply
voltage of the power supply may vary greatly when the load is open
or closed if the capacity of the power supply is not large enough.
Make sure that the capacity of the power supply is large enough so
that the supply voltage range will be always from 90% to 110% of the
rated supply voltage.
The E5C2 operates at either 50 or 60 Hz.

Precautions
Mounting
Track Mounting (E5C2 with P2CF-08)
When mounting two or more E5C2 models with track-mounting sockets, leave a space of approximately 20 mm on both sides of the sockets where hooks are located.

Panel
Flush Mounting
Insert E5C2 into the square hole of the panel and insert an adapter
from the back so that there will be no space between E5C2 and the
panel. Then, secure the E5C2 with a screw.
Tightening screw
Temperature
Controller
The P3G-08 can be wired in the same way as the P2CF-08.
Dismounting
If flush mounted, loosen the screw of the adapter and disengage the
hooks for dismounting.
Temperature Setting
Do not turn the temperature setting knob of the E5C2 with excessive
force, otherwise the stopper of the knob may break.
Others
Do not remove the housing of the E5C2, otherwise the housing may
break.
To clean the surface of the E5C2, use a soft cloth wet with neutral
detergent or alcohol. Do not use any organic solvent, such as paint
thinner or benzine, strong acid or strong alkali to clean the surface of
the E5C2, otherwise the surface of the E5C2 will become damaged.
