Ensure that the cables are not under tension.
Seals and terminal diagram:
Select suitable seals to fit the cable entries of the controller.

Close open holes with blanking plugs. This is the only way of
ensuring a sufficiently tight seal.
Moisture in the controller can lead to functional malfunctions.

protection IP 67 (mounted on a surface/pipe-mounted) or IP
54 (mounted on a control panel) (pollution degree 2/macro-
environment) can only be ensured if the device is correctly
mounted.

The cables and lines used need to be suitable for the respective
operating voltage, be made of copper and have a temperature
resistance of ≥ 70 °C.
The cables need to conform to UL 2556 VW-1 or similar. The indi‐
vidual wires need to be mechanically fixed or secured to prevent
them from loosening from the connecting terminals.
