GROUNDING THE INVERTER - AC GROUNDING
THOR inverters should always be connected to a permanent, grounded wiring system. An Inverter that is properly
grounded will reduce the risk of electric shock, reduce radio frequency noise. The main aim of any grounding
system is to provide a well-defined, very low resistance path from the electrical system to the grounding system.
The low resistance grounding path carries fault currents directly to ground if the electrical system malfunctions.
Grounding The power inverter has a lug on the rear panel: "Chassis Ground." This is to connect the chassis of the
power inverter to the ground. The ground terminals in the AC outlets on the front panel of the inverter are also
connected to the ground lug. To ground your THOR inverter, connect grounding wire to one of the mounting screws
and sand the connection before attaching the wire. The chassis ground lug must be connected to a grounding point,
which 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.
CAUTION This inverter cannot supply power to any AC distribution wiring or AC loads in which the neutral and
ground are connected (bonded). Doing so will destroy the unit and void the warranty. If you do not understand
neutral to ground bonding then please have a professional install your system for you. See "Grounding" for more
information.
CAUTION Do not connect this inverter and another AC source (generator or utility power) to the AC wiring or AC
loads at the same time. Doing so will destroy the inverter and void the warranty, regardless whether the inverter is
switched on or off. If you are using more than one AC source for the AC wiring or AC loads, it is highly recommended
that you install an automatic transfer switch (THTS), available from THOR Manufacturing

IMPORTANT CABLE INFORMATION:

Substantial power loss and reduced battery operating time results from inverters installed with cables that are not
able to supply full power. Symptoms of low battery power can result from cables that are either excessively long or
an insufficient gauge. Marine installations are also subjected to vibration and stresses that exceed those of other
mobile installations. Therefore, the installer/operator should be especially aware of the requirements to maintain
secure, tight, water-resistant electrical connections and to provide for strain relief for DC cables and appliance
wiring. Cable insulation must be the appropriate type for the environment.
Connecting the AC Wiring
AC connections are made on the terminal block located inside the front panel of the inverter.
