DANGER!
For safety reasons, all PE ground conductors must be connected prior to initial
operation.
The EN 61800-5-1 regulations for protective earthing must be complied with during
installation!
7.1 Operation with long motor cables
Compliance with the EMC standard EN 61800-3 is only guaranteed for motor cable
lengths of up to 25 m. For cable lengths beyond this a new measurement of the
interference emission may possibly be required.
In applications involving long motor cables and/or unsuitable motor cables with an inadvertently high
cable capacity, the filters may be thermally overloaded. To avoid such problems we highly recommend the
following procedure for applications that require long motor cables:
With cable lengths of more than 25 m use only cables with a capacitance per unit length between the
motor phase and the shield of less than 150 pF/m!.
(Please contact the motor cable supplier, if necessary.)
For motor cable lengths of more than 25 m and up to 50 m the following derating applies regardless
of the EMC qualification (see also Derating of the cable length on page 17):
