LETHAL VOLTAGES - Power modules generate output voltages up to 160 VDC! Ensure
that all instrument connections, load wiring, load and sense connections are insulated.
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.
The Line switch turns the unit on or off.
It may take about 30 seconds or so for the power system 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. The green LED above the power switch will illuminate when the power switch is on and
the input power is within the ac input rating required by the instrument.
If the front panel indicates "No Module Installed", even though a power module is installed in the
designated channel, check to make sure that the lockout bar is in place.
If a self-test error occurs, the self test error will be noted in the Error queue. Refer to
Service and Maintenance for instructions on returning the instrument for service.
