RMX Programmable Power Supplies Safety Information & Installation Guide
Turning the Power On
Turning the POWER Switch On
Caution
Risk of electric shock. 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.
Load Cables
Caution
Risk of fire. Use load cables whose capacity is adequate for the RMX
programmable power supply’s rated output current. The output connector and its
surrounding area become hot. Use cables whose covers have heat resistance at 85 °C
and higher.
Caution
Risk of electric shock. Use the cable which has higher withstanding voltage
than the specified insulation voltage of the product to secure the double insulation or
reinforced insulation.
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.
