8.15 Examples of correctly and incorrectly connecting NE
to the line supply
8.15.1 Three--conductor connection to the line supply
Note
S All X181 connections of a drive group must be electrically switched in
parallel!
S A maximum of four monitoring modules may be c onnected at X181 of an
NE module.
S 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).
S For all of the following examples, cables must be routed so that they are
short--circuit and ground--fault proof (or fuse)!
