AC Output Wiring

CAUTION:

 The inverter’s AC output must never be con-

nected to an AC power source. This will cause severe 

damage to the inverter and is not covered under war-

ranty.

When hardwiring the output of the inverter, a cable must be routed 

from the inverter’s output to an AC distribution panel (sub-panel) 

that provides overcurrent protection to the loads powered by the in-

verter. Connect the AC output to this distribution panel as described 

below:

1. Remove the 1/2” knockout on the AC Output Connection 

(see Figure 4, Item 15) – use a utility knife to cut thru the round 

slot. 
2. Discard this knockout and install a 1/2” strain relief in the AC OUT 

opening. You may need to 

fi

 le the opening edge for proper 

fi

 t. 

3. Run a 2-conductor plus ground cable through the strain relief in 

the AC OUT opening. Refer to Table 4 for the minimum wire size and 

the overcurrent protection required for the AC output wiring.
