Wiring according to EMC (installation of a CE-typical drive system)
Shield connection system
Use an appropriate clip to connect the shield to the conductive mounting plate of
ƒ
the control cabinet.
The connection should be as close to the cable end as possible.
ƒ
If possible, cover the shield end with a shrink tube.

Fig.13-2
Carefully connect shields, ground connections (GND), and earth potential connections (PE)
to avoid interferences:
Do not interrupt shielding.
ƒ
If an interruption cannot be avoided:
ƒ
– Connect the shields at interruptions (terminal strips, relays, fuses) with a large
surface and both ends to the mounting plate.
The cables must be laid as close as possible to the reference potential (dangling
ƒ
cables are like antennas).
Earthing
Ensure a good equipotential bonding of all system parts (934x regenerative power supply
module, controller, mains filter etc.) by cables to a central earthing point (PE bar). The
minimum cross-sections of the cables must be strictly observed.
Filtering
Only use the filters assigned to the regenerative power supply module :
ƒ
– Mains filters reduce non-permissible high-frequency interferences to permissible
values.
