The LEDs on the rectifiers and the
controller will emit light.
The rectifier fans will start.
The LVD contactors will operate.
1 Connect/switch on the mains supply
fuses/circuit breakers of the DC shelf. The green LEDs of the rectifiers and
the controller will flash for about 10 s.
and then emit steady light.
2 Check the DC voltage on the test outlet
marked U in the supervision unit.
The voltage should be close to what
has been set in the controller.
If temperature compensated charging
is activated, the difference may be ±3
V from the set value.
3
If temperature compensated
charging is activated, warn the
sensor on the battery with your hand
and observe the system voltage.
The voltage should start to drop.
4 Switch on the battery circuit breakers.
The battery voltage will increase and
reach the system voltage.
(Might take hours, depending on the
charging state of the battery.)
5 Switch on the circuit breakers in MFU. The loads will get DC supply.
6 Check all the LEDs of the shelf. Only the green LEDs are On should
emit light. No LED shall flash.
