3.8.2 Prior to Operation
a) Ensure that the power supply is configured to the default setting:
 On/Off switch at Off position.
 Dip switch: All positions at Down (“Off”) position.
 J2 Sense connector: Configured to Local Sense as shown in Fig. 3-4:
1 Remote (+) sense
2 Local (+) sense
3 Not connected
4 Local (-) sense
5 Remote (-) sense
Fig.3-4: J2 Sense connector default connection
Plug P/N: MC1,5/5-ST-3,81
(Phoenix)
 For units equipped with IEEE option, ensure that the IEEE_En switch is in Up
(default) position (Refer to Fig.4-2, Item 9 for location) if checkout is to be done in
IEEE mode.
b) Connect the unit to an AC source as described in Section 3.7.
c) Connect a DVM with appropriate cables for the rated voltage to the output terminals.
d) Turn the front panel AC power switch to On.
3.8.3 Constant Voltage Check
a) Turn on the output by pressing the OUT pushbutton so the OUT LED illuminates
a) Observe the power supply VOLT display and rotate the Voltage encoder. Ensure
that the Output Voltage varies while the VOLT encoder is rotated. The minimum
control range is from zero to the maximum rated output for the power supply model.
b) Compare the DVM reading with the front panel VOLT display to verify the accuracy
of the VOLT display. Ensure that the front panel VOLT LED is On.
c) Turn Off the front panel AC power switch.
3.8.4 Constant Current Check
a) Connect a DC shunt across the output terminals. Ensure that the shunt and the wire
current ratings are higher than the power supply rating. Connect a DVM to the
shunt.
b) Turn the front panel AC power switch to the On position,
c) Turn On the output by pressing the OUT pushbutton so the OUT LED illuminates.
d) Observe the power supply CURRENT display and rotate the CURRENT encoder.
Ensure that the Output Current varies while the CURRENT encoder is rotated. The
minimum control range is from zero to the maximum rated output for the power
supply model.
e) Compare the DVM reading with the front panel CURRENT display to verify the
accuracy of the CURRENT display. Ensure the front panel CURRENT LED is On.
f) Turn Off the front panel AC power switch.
g) Remove the shunt from the power supply output terminals.
3.8.5 OVP Check
Refer to Section 5.3 for explanation of the OVP function prior to performing the
procedure below.
a) Turn the front panel AC power switch to the On position and turn on the output by
pressing OUT pushbutton.
b) Using the VOLT encoder, adjust the Output Voltage to approx. 10% of the unit
voltage rating.
c) Momentarily press the OVP/UVL button so that the CURRENT display shows
“OUP”. The VOLTAGE display will show the last setting of the OVP level.
