C.2 Electrical Wiring
Danger
Before working on the unit, switch off the power supply and secure
it against being switched on again! Check for the absence of power!
Electric wiring may only be done by a specialist in compliance with valid
rules. Do not use the controller if its case shows visible damage.
Low-voltage cables such as temperature sensor cables must be routed
separately from mains voltage cables. Feed temperature sensor cables
only into the left-hand side of the unit, and mains voltage and relay
cables only into the right-hand side.
The controller is not equipped with a mains switch. For this purpose
please use e.g. a circuit breaker.
The cables being connected to the unit must not be stripped by more
than 55 mm, and the cable jacket must reach into the housing just to the
other side of the strain relief.
