2.4 Connection of the AC wiring
Use one of the following procedures below to wire the AC conductors.
Open the circuit breaker box, switch off and lock out the circuit breaker box that will be used to connect the inverter to the
building.
WARNING!
Reconfirm that the circuit breaker to the grid/utility is switched OFF and locked out before connecting the power
wires from the breaker to the inverter AC terminal block. Measure the absence of voltage with an AC voltmeter.
WARNING!
!
Long wires cause voltage drop. The acceptable range for AC voltage drop is 1.5% of nominal. The voltage drop in
excess of 1.5% of nominal AC voltage is an indication that larger size wire should be used.
