Turning the switch –S10 into position
0
will open the circuit-breaker if it is closed or stop the possible
ongoing pre-charging regardless of the selected control place/manner.
Turning the switch into position
1
enables the pre-charging and the circuit-breaker to be controlled by the
selected mode of the
REM-MAN-AUTO
selector switch.
Turning the switch into position
Start
will start the pre-charging of DC busbar. The pre-charging takes
about 5-10 s depending on the size of the drive. When DC voltage has reached a certain level the AFE
control unit will automatically close the circuit-breaker. The
Start
position of the switch is spring-retuned
and the switch will automatically return to position
1
when released. The pre-charging can be aborted by
turning the switch to position
0
. In case of a blackout in the supplying network, the under-voltage release
coil will open the circuit-breaker. Pre-charging and MCCB closing have to be activated by the operator
when the supply is energized.
The
AFE Ready
LED will illuminate when the MCCB is closed and AC power is connected to the AFE unit
and there are no active faults. The AFE ready LED works in the same way irrespective of the operation
manner/place.

The Run command has to be given to the AFE unit from the keypad, I/O signal or bus communication before
the inverter INU can be started (operated).
7.1.2 Remote operation (REM)
It is possible to control the circuit-breaker and the charging circuit from a remote location/system with
potential-free contacts while the MCCB control switch –S6 is in
REM
position.
Normally closed (NC) contact has to be connected to terminals X1:60 and X1:61 (terminal name can vary
depending on the frame size). This contact has to be in the NC state before the pre-charging can be
activated. Opening this contact will open circuit-breakers and stop the ongoing pre-charging.
A remote pulse duration (0.4-1s) connected to terminals X1:57 and X1:58 will start the charging of the
drive, and when DC voltage has reached a certain level, the AFE unit will automatically close the circuit-
breakers (terminal name can vary depending on the frame size). The Run command has to be given to the
AFE unit from the keypad, I/O signal or bus communication before the inverter INU can be started
(operated).
