Cable laying
All control cables (including thermistors) must be routed separately from the mains and the motor
cables to prevent interference in the device.
If the cables are routed in parallel, a minimum distance of 20 cm must be maintained from cables
which carry a voltage of > 60 V. The minimum distance may be reduced by screening the cables
which carry a voltage, or by the use of earthed metal partitions within the cable conduits.
Alternatively: Use a hybrid cable with shielding of the control lines.
