Chapter 1 Installation and Preparation
Connecting to the Output Terminals
Caution Risk of electric shock. Turn the POWER switch off before you touch the
OUTPUT terminals. Even if you turn the output off or turn the POWER switch off,
if the bleeder on/off setting (CF11) is set to “OFF,” the voltage that was present when
the output was on will remain at the output terminals. Turn the bleeder circuit on
before you touch the output terminals. Regardless of whether load cables are
connected to the output terminals, be sure to attach the OUTPUT terminal cover
before turning the POWER switch on. Confirm that the voltage between any output
terminal and ground is lower than the isolation voltage of the RMX programmable
power supply.

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.
