DC Connection Using the XGI Attachable Combiner Box

Electric Shock Hazard
Components with hazardous voltage and energy pose the risk of electrocuting operators.
Verify the absence of DC voltage and current.
Turn DC Switch to OFF
Verify the absence of DC voltage and current.
Check Polarity of DC Inputs
DC inputs with the wrong polarity may cause damage to inverter.
Confirm proper polarity of connections with a multimeter.
The PV Output Circuit Wiring Harness Assembly is designed to simplify the field interconnection of the
Combiner and the XGI 1500 inverter. The Wiring Harness Assembly comprises:
A straight section of 2-inch PVC about 7-inches in length, with 90-degree elbows and threaded

couplings at each end
Two (2) 4/0 AWG conductors for the PV Output Circuit overall positive (red) and overall negative

(black), with lugs crimped on the ends of the wires to facilitate termination on posts in the
Combiner and the XGI 1500 inverter, and
A 4AWG green equipment ground wire, with stripped ends for easy termination at the busbars in

the Combiner and XGI 1500 inverter.
