Note
S
All X181 connections of a drive group must be electrically switched in
parallel!
S
A maximum of four monitoring modules may be connected 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

For all of the following examples, cables must be routed so that they are
short–circuit and ground–fault proof (or fuse)!

incorrectly connected to
the line supply:
S
Possibly damage to the
hardware
S
Possible errors on the
drive bus
