Connection Order for DC Cables
CAUTION: Reverse polarity
Before making the final DC connection, check cable polarity at
both the battery and the inverter. Positive (+) must be connected
to positive (+); negative (–) must be connected to negative (–).
Reversing the positive (+) and negative (–) battery cables will
damage the inverter and void your warranty.
WARNING: Fire hazard
Use only appropriately sized copper cable. Make sure all DC
connections are tightened to a torque of 2.2–2.6 lbf-ft
(3.0–3.5 Nm). Loose connections will overheat.
