Routing cables and electrical connection
Routing electrical lines and connections may be performed only by approved specialist companies. Never
operate drives, control units, operating elements and sensors at operating voltages and connections contrary
to the specifications of the manufacturer.
All disconnecting devices shall be installed in the permanent electrical installation or external Control Unit for
the drive. The main supply lines 230 V / 400 V AC need to be protected separately! Damage to main supply
lines of drives with plug connectors may only be re- placed by the manufacturer or qualified service /
maintenance personnel!
Power cables fixed to the drive casing cannot be replaced. If the cable is damaged the device must be
scrapped!
The types of cable, cable lengths and cross-sections will be selected in accordance with the manufacturer’s
technical data. If necessary, the able types should be coordinated with local experts. Low-voltage lines (24 V
DC) need to be routed separately from high voltage lines. Flexible cables should not be flush-mounted and
freely suspended cables need to be equipped with strain reliefs.
Cables need to be laid so they cannot be sheared, twisted or bent during operation. Drive cables laid into
closed window profiles must be protected by insulating tubes with a sufficient temperature resistance.
Through holes shall be equipped with cable sleeves!
