safety, load wires must have a wire gauge size large
enough to prevent overheating when the power
supply operates at maximum short circuit output
current. Ensure the voltage selector is in the proper
location (110V or 220V), failing to do so will result in
damage to the DUT and/or power supply.
SHOCK HAZARD
Hazardous voltages may exist at the outputs and the
load connections when using this power supply. To
protect personnel against accidental contact with
hazardous voltages, ensure that the load and its
connections have no accessible live parts. Ensure that
the load wiring insulation rating is greater than to the
maximum output voltage of the power supply.

Preliminary Check
Complete the following steps to verify that the power supply is ready for use.
1.
Verify AC Input Voltage
Verify and check to make sure proper AC voltages are available to power the instrument.
The AC voltage range must meet the acceptable specification as explained in “2.1 Input
Power and Fuse Requirements”.
2.
Connect Power and Self-Test
Connect AC power cord to the AC receptacle in the rear panel and press the power
switch to the |(ON) position to turn ON the instrument. It will display the BIOS version
then run through a self-test procedure with the screen shown in below:
BIOS Ver 1.10
