Installation
12LPC15 Manual
DC Wire Gauge & Fusing
WARNING: Damage to the power inverter will occur if correct polarity is not observed when installing the
inverter’s DC input cables.
Inverter Cable
Wiring should meet all local codes and standards and be performed by qualified personnel such as a licensed
electrician.
An inverter cable kit (positive cable, negative cable, and proper fuse) is needed to connect the inverter to a battery
bank. An inverter cable kit designed to SAE guidelines can be purchased directly from Sensata – call for options.

NOTE: Using a smaller cable may cause a low battery or high temperature fault.
NOTE: 100% duty rating assumes the inverter is continuously operating at its full rated output power for at least an
hour. The 50% duty rating assumes that the inverter is operating at its full rated output power for up to 15 minutes
and then operating with a load less than 25% of its full rating for at least 15 minutes before returning to full power
and repeating. Alternatively, the inverter can also continuously operate at 50% of its rated output power. Values in
the provided table assume the inverter is operating in an ambient temperature of 25°C (77°F). For higher ambient
temperatures, additional derating may be required (i.e. may need to use a larger cable size).
