Table A–Recommended wire size versus current
Remarks: 1. Total Power Rating (VA, W) = No. of shelf × Inverter module power rating (VA, W) * 2
2. I/P current = Total power rating (W) ч 0.88 ч 40
3. O/P current = Total power rating (VA) ÷ AC voltage

Single Inverter Shelf System
1. In the inverter shelf package, you will find a jumper.
When only ONE inverter shelf is applied in the system, insert
the jumper to pins 1 and 2 of connector JP2:
2. Negative (BAT-) and positive (BAT+) DC input terminal studs are located in the left side of backplane. In
consideration of the power rating and distance from the battery, choose appropriate gauge wire using Table A
as well as local wiring rules.
NOTE:
For inverter systems without a controller, open collector terminals are available on the inverter shelf backplane for
the inverter fail alarm. See details under point 9 of Section 4.5.
