3.2 Electromagnetic compatibility (EMC)
If drives are to be operated via a common DC bus, the following
aspects must be considered in terms of EMC:
• Keep DC bus cables as short as possible.
• Shielded DC bus cables must be used at a cable length of > 0.2 m.
In the case of shielded DC bus cables, connect the cable shield to
the shield connection (large surface area contact).
3.3 DC bus connection
The DC bus is connected by means of a plug and socket connection
or screw terminals.
See the manual of the respective product for tightening torque of the
screw terminals.
Cable specifications See chapter "2.4 Cables for the DC bus", page 20 for the cable speci-
fications. Connector kits and pre-assembled cables can be found in
chapter "6 Accessories and spare parts", page 55.
