We recommend that all power cables are screened.
!
Important
Screens should be used in the overall protective grounding concept. Open–cir-
cuit or unused cores/electrical cables which can be touched, should be con-
nected to protective ground. If the brake feeder cables in the SIEMENS acces-
sory cables are not used, then the braking cable conductors and screens must
be connected to the cabinet ground. (open–circuit cables result in capacitive
charges!)
The assignment, motor cross–section power connector is specified in the ap-
propriate motor chapters.
4.2 Signal cable
Pre–assembled cables offer many advantages over self–assembled cables. In
addition to guaranteeing the correct function and the high quality, there are also
cost benefits.
In order to eliminate any effects of noise, the signal cables must be routed sepa-
rately away from the power cables.
Note
The maximum cable lengths, specified in the connection overviews, must be
observed.
The signal cables used are described for the appropriate encoders
(refer to Chapter GE).
