Operating Manual for XPR Series Power Supply
Power ON
Check
To complete the power on check:
1. Ensure that the AC power switch is OFF.
2. Connect the unit to an AC outlet.
3. Turn the front panel AC power switch to ON.
After a short power-on delay, the front panel meters and the CV annunciator
illuminate. Both voltmeter and ammeter displays should read zero.
Check the front panel annunciators. If the ON LED is illuminated, press OUT
ON/OFF button to disable the output. The OFF LED should now be illuminated. If
the LCL LED is illuminated, the power supply control is in Local Mode. If the RMT
LED is illuminated, the power supply control is in Remote Mode. For an illustration
of the annunciators and their locations, see
“Status Annunciators” on page 19 .
AC Protection will disable the output if the AC line drops or is over the acceptable
range. The AC LED turns off when the input voltage is within the range.
If you observe or suspect that one or more of the display LEDs is malfunctioning,
contact the manufacturer.
WARNING
On units rated higher than 40V, ensure that the electrical connections are protected
to prevent accidental contact.
!
CAUTION
When making connections to the bus bars, ensure that each terminal’s mounting
hardware and wiring assembly are placed so they don’t touch the other terminal and
short the power supply outlet. Heavy connecting cables must have some form of
strain relief so the connections aren’t loosened and the bus bars aren’t bent.
