1. Turn the POWER switch off. Check that there is no voltage across the output terminals.
2. Connect one end of the included chassis connection wire to the chassis terminal, and then
connect the other end of the wire to the negative or positive output terminal.
Note For safety reasons, connect one of the output terminals to the chassis terminal
unless your application requires the output terminals to be floating
Use the screw on the RMX to connect the wire to the chassis terminal. Use the screw on the
output terminal to connect the wire to the output terminal.

3. Attach crimping terminals to the load cables.
The output terminals have holes for connecting the load cables. Use crimping terminals that
are appropriate for the bolts that you are using.
4. Use the included bolt set to connect the load cables to the output terminals.
Connect the positive cable to the positive output terminal and the negative cable to the
negative output terminal. The orientation of the crimping terminals will vary depending on
the wire diameter of the load cables used.
