SHOCK HAZARD, LETHAL VOLTAGES - Many models generate output voltages up to
2,000 VDC! Ensure that all instrument connections, load wiring, load and sense
connections are insulated using high-voltage wire. Always attach the safety cover
provided, so that no accidental contact with lethal voltages can occur.
Verify that the line cord is connected and plugged in.
Turn the unit on with the front panel power switch. The front panel display will light up after a few
seconds. A power-on self-test occurs automatically when you turn the unit on. This test assures you
that the power supply is operational.
It may take about 30 seconds or so for the power supply to initialize before it is ready
for use.
If the instrument does not turn on, verify that the power cord is firmly connected (power-line voltage is
automatically sensed at power-on). Also make sure that the instrument is connected to an energized
power source. If the LED next to the power switch is off, there is no ac power connected. If the LED is
amber, the instrument is in standby mode with ac power connected, and if it is green, the instrument is
on.
If a self-test error occurs, a message is displayed on the front panel. For other self-
test errors, see
instrument for service.
