Calculating Cable Sizes
To operate safely and effectively, the XM Series Inverter needs proper
cables and fuses. Because the XM Series Inverter has low-voltage and
high-current input, it is essential that you use low-resistance wiring
between the battery and the inverter to deliver the maximum amount of
usable energy to your load.
For safe and efficient operation, you will need to calculate cable sizes for
your:
•
DC input cables from the battery to inverter (one way)
•
Chassis ground cable from the grounding point to the chassis ground
screw on the inverter’s DC panel.
See Figure 3-3 on page 3–12.
Calculating Size of DC Input Cables
Refer to Table 3-1 to plan the DC input cabling for your application:
•
Use only cable rated for 90 °C
•
Oil-resistant cable is recommended
•
Keep all cables as short as possible, and ensure that each cable
between the inverter and the battery is no longer than 5 feet (1.5 m)
•
Do not use aluminum cable. It has about 1/3 more resistance than
copper cable of the same size, and it is difficult to make good, low-
resistance connections to aluminum wire.
WARNING: Fire hazard
Never use a DC cable longer than 5 feet (1.5 meters). A cable longer than 5 feet
(1.5 meters) can potentially generate enough heat to start a fire or result in poor
inverter performance.
