4.1 Power cables
Shielding
AL S
Assignment
ALS/4-38
We recommend that all of the power cables are shielded.
Important
!
Shields 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 feed cables in the SIEMENS cables
are not used, then the braking cable conductors and shields must be connec-
ted to the cabinet ground (open–circuit cables result in capacitive charging!).
The assignment, motor – cable cross–section – power connector is specified in
the appropriate motor chapters.
