Function: Isolating from the line supply
In operation, terminals 151 - 152 and 153 - 154 must remain closed; when they are opened, the
unit is isolated from the line supply.
If isolation from the line supply is required, both terminals must be opened, in order to avoid er-
roneous function when a ground occurs.
When the terminals are opened, the auxiliary circuits are in a no-voltage condition, and the
open-loop and closed-loop control does not function.

Control for pre-charging- and
main contactor with checkback
signal (NO contact) for the main
contactor.
The customer must establish the connection from the line
filter to the drive converter after mounting. Insert the cable
assembly with connector (coming from the line filter) into X5.
