8.15.2 Six–conductor connection to the line supply
Note
All X181 connections of a drive group must be electrically switched in
parallel!
All of the jumpers at X181 must be removed!
A maximum of four monitoring modules may be connected at X181 of an
NE module.
If a DC link is buffered (DC link connection), the voltage must always be
taken from between the reactor (L
K
) and the line supply infeed (NE).
Different line supplies may be used, e.g. using UPS.
For all of the following examples, cables must be routed so that they are
short–circuit and ground–fault proof (or fuse)!
