Wiring on the mains side
ƒ It is possible to connect the controller, mains choke or RFI filter to the mains via
single cores or unshielded cables.
ƒ The cable cross−section must be rated for the assigned fuse protection (VDE 0160).
Wiring on the motor side
(
Stop!
The motor cable is highly susceptible to interference. Therefore you will
achieve an optimum wiring on the motor side if you
ƒ exclusively use shielded and low−capacitance motor cables.
ƒ do not integrate any further cable into the motor cable (e.g. for blowers
etc.).
ƒ shield the supply cable for temperature monitoring of the motor (PTC or
thermostat) and install it separately from the motor cable.
Special conditions allow you to integrate the supply cable for temperature monitoring of
the motor into the motor cable: (

Danger!
Uncontrolled motor movements can occur
If the motor cable is damaged, a short circuit between the brake control cables
and the motor cables can cause motor movements with low torque.
Possible consequences:
ƒ Personnel in the vicinity of the motor can be injured.
Protective measures:
ƒ Install motor cable in a protected way (e.g. in a cable duct).
