Warning
!
The grounding bar is used for high–resistance connection and balancing of the
DC link to the ground. It must always remain inserted.
The grounding bar must be opened only if a high–voltage test is performed.
Note
Electrically disconnecting the line supply from the power circuit of the drive
group using the internal line contactor.
The coil circuit can be disconnected in order to reliably open (de–energize) the
line contactor using external electrically isolated contacts via terminals NS1,
NS2 at the NE module. The DC link is not pre–charged if the connection is
missing when the unit is powered–up. The state of the contactor (whether it is
open/de–energized) can be interrogated using terminals 111, 113, and 213.
The NS1, NS2 connection may only be opened if terminal 48 and/or terminal
63 are de–energized using a leading contact, or is simultaneously opened
when these terminals are de–energized, refer to Section 8.7.
