First Power-Up - Nuvation Energy NUVG5 Product Manual

4.5. First Power-up

Once the G5 Cell Interface modules chain and the G5 Stack Switchgear are connected to the battery,
the G5 Stack Switchgear can be powered (internal power and fan power).
Power on the G5 Stack Switchgear
Put the Service Disconnect switch in the Operating position. The power LED (green) will turn ON to
indicate that the G5 Stack Switchgear is powered.
For more details on the Status LEDs, please refer to
Clear Faults
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.
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. Once all faults are cleared, the Stack Switchgear is able to connect the battery to the DC
bus.
