3.2 Connecting to the Extended Battery Cabinet
To be performed by authorized service personnel:
1.
Inspect battery trays for signs of damage. Verify that all terminal connections are sound.
The red and black “powerpole” connectors will be connected, but the blue and white
connectors on the wires joining the trays in the string should not be connected.
2.
If possible, after connecting the loose “powerpole” connections (blue to blue, white to
white), use a voltmeter to verify that the battery string is above 408 VDC at the TB3
connector. If the voltage is low or the voltage varies significantly from string to string,
please consult Dual-Lite service.

3.
The battery cabinet(s) to be installed must include the at least one –B version. The first
–B cabinet must have its input terminal block (TB1) wired directly to the UPS. To wire
additional battery cabinets, wire from TB2 of the first battery cabinet to TB1 of the
second –B battery cabinet. Repeat these steps for additional –B cabinets. Use wire
sized per local codes, #6 AWG 75° C copper wire minimum to #2/0 AWG maximum.
When a –N version cabinet is installed with a –B cabinet, the –B cabinet must have its
TB1 terminal block wired to the UPS or another –B cabinet. To wire from the –B cabinet
to the –N cabinet, wire from TB3 of the –B cabinet to TB1 of the –N cabinet. To wire
additional –N battery cabinets, wire from TB2 of the first –n battery cabinet to TB1 of the
second –N battery cabinet. Repeat these steps for additional -N cabinets.
There must be at least one –B cabinet among the battery cabinets. If it is desired to
create a battery system involving all –N version cabinets and a user provided disconnect
switch, contact Dual-Lite for requirements for the disconnect switch.
DANGER
TB3 is energized at all times. Opening the circuit breakers does not remove
power from this terminal block.
4.
Connect the ground wire to the ¼-20 ground stud with a ring terminal or pressure lug by
removing and replacing the top nut and washers only with a 7/16” wrench.
