 Testing between the input terminal and
grounding terminal
1. Lay transition wiring between terminals 1, 2,
3, 4 and 5 of the terminal box, and connect the
insulation resistor (with the power turned OFF)
between the transition wiring and the grounding
terminal. The polarity of the transition wiring
must be positive and that of the grounding
terminal must be negative.
2. Turn the power of the insulation resistance
meter ON and measure the insulation
resistance. The duration of the applied voltage
must be the period during which 100MΩ
or more is conrmed (or 20MΩ if the unit is
equipped with a lightning protector).
3. Upon completion of the test, remove the
insulation resistance meter, connect a 100KΩ
resistor between the transition wiring and the
grounding terminal, and allow the electricity to
discharge. Do not touch the terminal with your
bare hands while the electricity is discharging
for more than 1 second.
2.6.2 Withstand voltage test procedure
 Testing between the output terminal and
the input terminal
1. Lay transition wiring between the + terminal,
the – terminal, and the check terminal of the
terminal box.
2. Lay transition wiring between terminals 1, 2, 3,
4 and 5 of the terminal box.
3. Connect the withstand voltage tester (with
the power turned OFF) between the transition
wiring shown in Steps 1 and 2 above.
4. After setting the current limit value of the
withstand voltage tester to 10mA, turn
the power ON, and carefully increase the
impressed voltage from 0V to the specied
value.
5. The voltage at the specied value must remain
for a duration of one minute.
6. Upon completion of the test, carefully reduce
the voltage so that no voltage surge occurs.
 Testing between the output terminal and
the grounding terminal
1. Lay the transition wiring between the + terminal,
the - terminal and the check terminal of the
terminal box, and connect the withstand voltage
tester (with the power turned OFF) between the
transition wiring and the grounding terminal.
Connect the grounding side of the withstand
voltage tester to the grounding terminal.
2. After setting the current limit value of the
withstand voltage tester to 10mA, turn the
power ON, and gradually increase the
impressed voltage from 0V to the specied
value.
3. The voltage at the specied value must remain
for a duration of one minute.
4. Upon completion of the test, carefully reduce
the voltage so that no voltage surge occurs.
 Testing between the input terminal and
the grounding terminal
1. Lay the transition wiring across terminals 1, 2,
3, 4, and 5 of the terminal box and connect the
withstand voltage tester (with the power turned
OFF) between the transition wiring and the
grounding terminal. Connect the grounding side
of the withstand voltage tester to the grounding
terminal.
2. After setting the current limit value of the
withstand voltage tester to 10mA, turn the
power ON, and gradually increase the
impressed voltage from 0V to the specied
value.
3. The voltage at the specied value must remain
for a duration of one minute.
4. Upon completion of the test, carefully reduce
the voltage so that no voltage surge occurs.
