Operating Instructions, 03/2012, A5E03263466A
The insulation monitor can only be operated on an ungrounded
line supply (IT system). Only one insulation monitor can be used
in an electrically-connected network. For line-side control, the
signaling relays must be connected accordingly or, with individual
drives (the cabinet unit is fed via a converter transformer
assigned to the cabinet unit), integrated in the cabinet unit alarm
train (see "Electrical installation / Other connections / Insulation
monitoring (option L87)").
Point 9 must also be observed:
"Before the drive is operated on an ungrounded line supply (IT
system), the connection clip to the basic interference suppression
device must be removed" (see Chapter "Electrical
installation/Power connections/Removing the connection clip to
the interference suppression capacitor for operation on
ungrounded line supplies (IT systems)").
The terminal block -X41 must be connected line-side, the safety
functions must be activated prior to use via parameter
assignment, in addition an acceptance test must be performed
and an acceptance log must be created (see section "Electrical
installation / Other connections / Terminal module for activating
"Safe Torque Off" and "Safe Stop 1" (option K82)").
