Turning Your Inverter On or Off
Be sure to have your power inverter properly installed before attempting to
turn the unit On (see “Installation” page 6).
To Turn the Power Inverter On:
1. If a DC power supply is being used as the power source, switch it On.
2. On the left side panel, switch the On/Off Switch to On.
The inverter is now ready to deliver AC power to your loads. If several loads
are to be operated by the inverter, turn them On separately, after the inverter
has been turned On. This will ensure that the inverter does not have to deliver
the starting currents required for all the loads at once.
To Turn the Power Inverter Off:
1. On the left side panel, switch the On/Off Switch to Off.
NOTE The On/Off Switch turns the control circuit in the inverter On and Off.
It does not disconnect power from the inverter.
When the switch is in the Off position, the inverter draws no current
from battery. When it’s in the On position, but no power is being supplied
to the load, the inverter draws less than 500 milliamperes from the battery.
This is low current draw. It would take more than a week to discharge a
100 ampere-hour battery at this rate depending on the age of the battery.

Ground Wiring
There is a screw on the rear panel for Chassis Ground. This is to connect the chassis
of the inverter to ground.
The Chassis Ground Screw must be connected to a grounding point, which will vary
depending on where the unit is installed. Use a #8 AWG copper wire (preferably with
green/yellow insulation) to connect the chassis ground screw to the grounding point.
In a Vehicle:
Connect the Chassis Ground to the chassis of the vehicle.
In a Boat:
Connect to the Boat Grounding System.
In a Fixed Location:
Connect the Chassis Ground Screw to earth ground by connecting
to a ground rod (a metal rod pounded into the earth) or other proper
service entrance ground.
