Connection overview
♦
Use shielded control cables. The shield is to be connected at the
transmitter end and at the receiver end.
In the case of analog control cables, two-end shield connection can
lead to hum pick-up. In this case, the shield must only be connected
at one end, at the converter.
♦
Lay control cables and power cables separately. Power cables in
this context are the motor cable or connecting cables from the
converter’s DC link (terminals C/ L+ and D/ L-) to other components,
e.g. brake resistor. Control cables and power cables must never be
laid parallel to each other in a single cable pit, even if all the cables
are shielded.
