Thermocouple input • If a single power supply is used for the E5C2 and the load, the

■ Correct Use
Mounting The P3G-08 can be wired in the same way as the P2CF-08.
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.
Duct If flush mounted, loosen the screw of the adapter and disengage the
hooks for dismounting.
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.
• Do not remove the housing of the E5C2, otherwise the housing
Tightening screw 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
