4.5. First Power-up
Once the Stack Switchgear is connected to the battery (including the Cell Interface modules chain), it
can be powered (internal power and fan power). The two breakers can be put in the closed (non-
tripped) position. The power LED (green) should turn ON.
On initial power-up, it is common to see that the fault LED (red) is also ON. This indicates that a fault
has been detected; the next step will be to clear this fault.
The service disconnect switch can be put in the
ON
position.
Faults are
latching
, i.e. will remain in faulted state until cleared even if fault condition is removed.
Begin by clearing all faults. If any faults remain, investigate the cause of each fault and resolve the
issue. The faults are described in the
. Once all faults are cleared, the Stack Switchgear
is able to connect the battery to the DC bus.
