Installing Your Power Inverter
Before installing your power inverter, review the warning section at the beginning of this manual and this Installation
section in its entirety. As previously noted, the power inverter should be installed and operated only by those
competent to install and operate it. (Refer to the Power Inverter Installation Schematic on page 11 for an example of
a typical installation.
Mount the Power Inverter
Do not mount the power inverter in the engine compartment (under the hood) of a vehicle (see Choosing an
Installation Location). Make sure that the power inverter is in the
The power inverter can be mounted in one of three orientations: 1.) horizontally on a vertical surface, such that the
ends are parallel (fan not facing up or down); 2.) on top of a horizontal surface; 3.) underneath a horizontal surface.
Care must be taken during the mounting process not to damage the power inverter in any way.
Remote Power Switch
Your power inverter includes a remote power switch that increases the versatility of the inverter when determining
your installation location. The remote switch allows the power inverter to be mounted in recessed or less accessible
areas when that is the preferred location. To install the remote switch, insert the switch connector into the remote
switch mount by orienting the connector key with the mount and pushing it in. Then, locate the remote switch in an
appropriate location for your needs. Remember that the unit power switch should be in the ON position in order for
the remote switch to be operable. To remove the remote switch, pull back on the collar and then pull the connector
out of the mount.
Connect the Chassis Ground
See Chassis Grounding Cable Requirements for details regarding ground cable requirements and connecting to
vehicle grounding points.
For certain applications, you are required to properly ground the inverter chassis. Your power inverter has a ground
screw for grounding the power inverter chassis. On model PI10000X, the ground screw is located at the bottom right
of the DC Input Panel. On Model Nos. PI15000X and PI20000X, the ground screw is located on the bottom panel
and is marked by a ground label.
When installing the ground connection to the power inverter, the power inverter should be turned OFF. For the
ground connection, permanently connect cables using properly rated connections and make sure that the cable
connections are tight.
Connect the DC Input Cables
See DC Input Cable Requirements for details regarding DC input cable requirements. Because the short circuit
current from your 12 volt power source battery(ies) can be extremely high, it is important to install a fuse or circuit
breaker between your power source battery(ies) and the power inverter (See Fuse/Circuit Breaker Requirements).
In preparation for making the DC connection, cut DC Input Cables to the appropriate length. Permanently connect
cables using properly rated connections and make sure that the cable connections are tight. The connection
sequence should be as follows:
Note: Take extra care to ensure that the polarities are properly matched throughout the connection process.
Positive always connects to positive, negative always to negative. Reversing the connection could result in
personal injury or property damage.
•
Install the fuse/circuit breaker to the power inverter DC terminals (See Fuse/Circuit Breaker Requirements),
making sure the disconnect switch or circuit breaker is turned
•
Make the positive (POS, +) battery connection to the fuse/circuit breaker, starting at the battery
•
Make the negative (NEG, -) battery connection to the power inverter, starting at the power inverter
•
We recommend coating battery connections in fixed applications with Dielectric Grease to maintain a good
electrical connection and prevent corrosion on terminals.
