Connections
Connecting the Input
•
Connect a thermocouple, the E52-THE@ Thermistor (replaceable
element) or a platinum resistance thermometer to terminals 1
(positive) and 2 (negative) on the E5C2 as shown in the following
illustration.
Output
•
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.
•
We recommend using an external relay to extend the electrical life
of internal relays when driving a large capacity load. This is
particularly important when the output relay is switched frequently
(e.g., with proportional control).
Platinum resistance
thermometer input
Thermocouple input
Power Supply
•
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.

•
On the E52-@@1D, the lead wires are thermocouple element wires,
making them difficult to solder because solder will not stick to them
easily. Remove the crimp terminal and polish the ends before
attempting to solder them.

Correct Use
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.
The P3G-08 can be wired in the same way as the P2CF-08.
Hook
Duct
Dismounting
If flush mounted, loosen the screw of the adapter and disengage the
hooks for dismounting.
P2CF-08
Panel
20
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.
Temperature Setting
Do not turn the temperature setting knob of the E5C2 with excessive
force, otherwise the stopper of the knob may break.
Others
Tightening screw
•
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.
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.
