Connect Power In And Fan Control - Nuvation Energy NUVG5 Product Manual

The G5 Stack Switchgear must be bonded to the rack or Earth through a suitably sized conductor by
NEC standards. From NFPA 70, Table 250.122, the wire size must be chosen based on the rating of
the automatic over-current device in the circuit, as shown in
An M8 lug (not included) should be used (e.g. Panduit Corp LCMA50-8-L), along with an M8 bolt and
tooth lock washer (both included), as shown in
In order to make the connection:
1. Strip the insulation
2. Crimp the lug
3. Screw the lug onto the terminal
The recommended tightening torque is 15 N-m [130 in-lbs].


If you are building your own cables, please refer to the pin out for this connector in
Power and Fan
The G5 Stack Switchgear requires a 100 V to 240 V AC or a 24 V DC power to be supplied from an
external source. Power is connected via feed-through connectors labeled 'Power In' on the front
panel. Power is connected via the Fan and Power In cable connector.
Fan control enables the G5 Stack Switchgear to control external AC or DC fans for cooling the battery
cells. The fans are enabled by the BMS when battery cell temperatures exceed configurable
thresholds.
The power source for the fans must be supplied to the G5 Stack Switchgear. It can be either AC or
DC, depending on the fan selection for the system. This can be the same power source used for
powering the G5 Stack Switchgear.
