4.4 Cables
DC to AC inverters require high amperage to operate properly; connect inverter DC input
terminals to battery with heaviest wire available; see Table 4-1.
Table 4-1: Wire Gauge
Max. Watts Out Approx. Amps Required (12 V DC) Wire Gauge*
3000 W >300 4/0
*It is recommended that the cable length not exceed 10 ft (3 m).
4.5 Inverter Fuse
A class “T” inverter fuse should be included in all installations.

4.6 Grounding
Do not install the power inverter in a positive ground DC system. A
positive ground DC system has the positive terminal of the battery
connected to the chassis of the vehicle or to a grounding point.
Do not operate the power inverter without connecting it to ground.
Electrical shock hazard may result.
The power inverter has a lug on the rear panel: "Chassis Ground." This is to connect the
chassis of the power inverter to a grounding point.
The power inverter grounding point will vary depending on where the power inverter is
installed. In a vehicle, connect the chassis ground to the chassis of the vehicle. In a boat,
connect to the boat's grounding systems. In a fixed location, connect the chassis ground
lug to earth.
The neutral (common) conductor of the power inverter AC output circuit is not bonded to
the chassis ground. Therefore, when the chassis is connected to ground, the neutral
conductor will not be grounded.
At no point should the chassis ground and the neutral conductor of the inverter be
bonded. Bonding the chassis ground and the neutral conductor of the inverter or
connecting the inverter to household or recreational AC distribution wiring will damage the
unit and void the warranty.
As per the national electrical code, electrical panels in mobile applications (boats, RVs
etc.) must not have a neutral to ground bond.
