DANGER!
For safety reasons, all of the PE earth (ground) conductors must be connected prior to the initial operation of
the system.
The EN 61800-5-1 regulations concerning protective earthing (grounding) must be complied with during the
installation!
8.14.5 Operation with long motor cables
In applications involving long motor cables and/or in the case of unsuitable motor cables with a non-permissible high cable
capacity, the filters may be thermally overloaded. To avoid these problems, we strongly recommend the following procedure
for applications requiring long motor cables:
 In the case of a cable length of more than 50 m, use only cables with less than 150 pF/m (capacitance per unit length)
between the motor phase and shield!
(Please contact the motor cable supplier, if necessary.)
 In the case of a cable length of more than 50 m, the frequency of the power output stage must be reduced.
