3-2 Basic Operation PAD-L
3.1 Turning on the power
In this section, the POWER switch is turned ON without a load to check the unit
operating conditions.
CAUTION
• Actual power is output during this procedure; do not attach a load
to the output terminals.
• To avoid overheating and damage to the internal circuits, leave
terminals 9 and 10 of the control terminal board free. AC voltage
will be output to those terminals.
Turning on the power procedure
1. Check that the POWER switch is turned off.
2. Make sure the AC power cord is connected properly.
3. Make sure nothing is connected to the output terminals.
4. Check the connections of the shorting bars at the output terminals.
Check that the sensing terminals are connected to the output terminals and that the
GND terminal is securely connected to the - (neg.) output terminal. See Fig. 3-1.
5. Check the connections of the shorting bars at the control terminal board.
Check that terminals 0 and 1, terminals 3 and 4, and terminals 5 and 6 are
securely connected. See Fig. 3-2.
6. Turn on the switch on the switchboard.
7. Turn the VOLTAGE setting knob fully counterclockwise.
8. Turn the CURRENT setting knob fully clockwise.
9. Turn on the POWER switch.
10. Check that the POWER indication lamp and C.V lamp are functional.
11. Turn the VOLTAGE setting knob clockwise so that the voltmeter
indicates the rated output voltage.

NOTE
• If the OVP trip point is set to a level less than the rated output voltage, the
POWER switch is turned off. For information on OVP, see 3.2.1 "OVP
(Overvoltage protection) trip point presetting".

12. Check that the ammeter pointer swings past the rated output current
when the CURRENT/VOLT. LIMIT switch is pressed.
13. Turn the CURRENT setting knob to the extreme counterclockwise
position to confirm that the C.C lamp lights.
14. Check that the voltmeter indicates the rated output voltage when the
CURRENT/VOLT. LIMIT switch is pressed.
