Main DC Wiring
NOTE: Main DC wiring must be in accordance with local
jurisdiction and codes. See Article 215.12(C)(2) in the
NEC for correct identification for DC Feeder conductors.
NOTE: Raceway connections to the generator must be
flexible. Ridged raceway connections to the generator
are only permitted where approved expansion fittings are
installed.
NOTE: Generator lugs are copper and rated at 167 °F
(75 °C).
1. Strip insulation off wire ends. Do not remove
excessive insulation.
2. See
Figure
6-1. Loosen lugs at ground (G) and
power wire (mains) terminals (RE+, RE-).
3. Connect ground wire to ground lug and tighten to
required specification. See
4. Insert power wires (RE+ and RE-) into their corre-
sponding polarity lugs. Tighten to required specifi-
cation.
5. Verify factory-installed ground array is correctly
tightened to 25 in-lbs (2.82 Nm).
6. With DC breaker off, measure resistance and verify
values between RE+ to RE- and to ground are
greater than 10 kOhms.
NOTE: See PWRcell Inverter owner's manual for DC
breaker wiring connections.
NOTE: Tighten all wiring lugs and connection points to
the required torque specifications.
Conductors of AC and DC circuits, rated 1,000 volts nom-
inal or less, shall be permitted to occupy the same equip-
ment, cable, or conduit. All conductors shall have an
insulation rating equal to at least the maximum circuit
voltage applied to any conductor within the equipment,
cable, or conduit. See NEC 300.3(C)(1).
NOTE: Only bare wire should be inserted into each ter-
minal. Do not insert any wire insulation into terminals.
NOTE: Damage caused by mis-wiring of the intercon-
nect wires is not warrantable.
Service Entrance Decals
See
Figure
2-10. Locate service entrance-related decals
in the loose parts bag.
•
Place service entrance warning decal in an appro-
priate location according to instructions printed on
the decal.
Battery Requirements
12 volts, Group 26R Wet Cell 540CCA minimum.
NOTE: Do not use external battery chargers.

Battery Installation
WARNING
Explosion. Batteries emit explosive gases while
charging. Keep fire and spark away. Wear protective
gear when working with batteries. Failure to do so
could result in death or serious injury.
WARNING
Risk of burns. Batteries contain sulfuric acid and can
cause severe chemical burns. Wear protective gear
when working with batteries. Failure to do so could
result in death or serious injury.
WARNING
Explosion. Batteries emit explosive gases.
Always connect positive battery cable first to
avoid spark. Failure to do so could result in
death or serious injury.
WARNING
Risk of burn. Do not open or mutilate batteries.
Batteries contain electrolyte solution which can cause
burns and blindness. If electrolyte contacts skin or
eyes, flush with water and seek immediate medical
attention.
•
(Unsealed 26R batteries only): Fill battery with
the correct electrolyte fluid if necessary.
•
Fully charge battery before installing it.
Complete the following steps before installing and con-
necting battery:
1. Verify generator is OFF.
2. Turn off REbus system connection by opening the
30A generator MLCB (generator disconnect).
3. See
Figure
6-2. Remove 15A fuse (A) from bottom
of converter.
