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 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 65mm, and
the cable jacket must reach into the housing just to the other side of the strain relief.
We recommend the use of
fl
exible cables to ease the installation in the clamp room.
Before working on the unit, switch off the power supply and secure it against being switched
on again! Check for the absence of power! Electrical connections may only be made by a
specialist and in compliance with the applicable regulations. Do not use the controller if the
housing shows visible damage.
An all-pole disconnecting device shall be installed for switching off the controller.
