8.15
Examples of correctly and incorrectly connecting NE
to the line supply
8.15.1
Three–conductor connection to the line supply
Note
All X181 connections of a drive group must be electrically switched in
parallel!
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).
For all of the following examples, cables must be routed so that they are
short–circuit and ground–fault proof (or fuse)!
