9.3 Motor Cable
Use shielded conductors for the motor in order to keep interference as low as possi-
ble (line cross-section according to the table). If possible, the shield should be con-
nected with both ends and largest surface. If this is not possible, the shield should be
connected with one end to the shield bar which can be supplied by SIEB & MEYER.
Requirements to the motor cable:
The maximum admissible length of the motor cable is 100m. The capacity must not
exceed 5.2nF.
Example: If the cable capacity is 0.26nF per meter, the maximum admissible length
of the motor cable is 20m.
Warning
Earth conductors additionally lead in motor cables must directly be
put to the earth shield and be marked with
7
.
If the procedure turns out to be impracticable, omit the earth conduc-
tor connection in the motor cables and wire a separate earth conduc-
tor in parallel to the motor cables preventing disturbing ground loops.
Warning
The maximum cable capacity is 5.2 nF.
The maximum cable length is 100m.
