Xantrex Technology XS400 manual DC Cables

Installing the XS400

DC Cables

For the best load starting performance, the DC cables should be as short and large as possible. See Table 2-1 for minimum recommended cable size. Using a smaller cable may cause the inverter to shut down under heavy load. A larger cable may be used.

Table 2-1Minimum Recommended DC Input Cable (copper) — AWG

Cable Length: Battery to Inverter	Minimum Recommended
(each cable)	Cable Size — AWG
0–10 feet (0–3 meters)	No. 6
10–15 feet (3–4.5 meters)	No. 4
