AC Input & Output Connections
WARNING: Do not connect another source of AC power directly to the output of the inverter. This will result
in damage not covered under warranty.
WARNING: Do not reverse the input and output AC connections. This will result in damage not covered under
warranty.
The inverter’s 120 VAC output power is provided at the GFCI receptacle and the hardwire terminal blocks behind
the access panel. Wire the AC input to the hardwire terminal blocks behind the access panel for charging and shore
power.
1.
Remove the black hole covers as needed for hardwire AC wiring. Use a Romex type clamp to protect the wires
from the metal edge of the hole.
2.
Apply 14.0 in-lbs torque to the terminal block screws on DIN rail style and 14.6 in-lbs on the white modular
style.
NOTE: Systems rated at 2400 watts and above, the AC input should be protected by a 30 A branch rated input
breaker external to the inverter/charger
NOTE: Connecting the AC inverter input to a GFCI protected outlet may cause some interference with the
inverter’s GFCI.
NOTE: The AC output should be protected by a branch rated breaker external to the inverter if required to comply
with the NEC, NFPA 70, or the Canadian Electrical Code, C22.1.
