Installation
When using an external power supply
Instead of using the included AC adapter, power can be
supplied externally.
Connect wiring using a MOLEX connector, as shown in the figure.
Please be sure to connect to ground. Otherwise a ground wire
may be connected to the ground terminal on the rear of the unit.
Please shut off the external power supply when stopping
operation.
Output monitor terminals
You can easily check the AC high voltage output by connecting a digital
multimeter or tester (1 M
Ω
or more of impedance) to the output monitor
terminals (MONITOR) on the side of the unit.
(A tester pin with an outer diameter of 2 mm will fit.)
1. Put the tester, etc. in AC voltage measurement mode, and connect it to
the output monitor terminals (MONITOR). Since there is no polarity, it
doesn't matter which side you connect to the COM terminal.
2. Once the power is turned on for the unit, a value that is 1/1000th that
of the AC high voltage output (AC 4 to 7 V) will be displayed on the tester. The high voltage output
voltage will be the value which is multiplied by 1000 of the displayed value.
Ex.: If the tester shows 4.2 V, the high voltage output will be 4.2 kV
CAUTIONS
CAUTIONS
• Be sure to conduct measurements with the tester in AC voltage
measurement mode.
• Do not apply a voltage to the output monitor terminals as it may lead
to failure.
REMEMBER
• Do not short the output monitor terminals or connect them to ground.
It may lead to failure.
Output voltage adjustment
Make sure to carry out output adjustment
while the ionizer is disconnected.
When the product has
been shipped together as a set with an ionizer, output voltage setting/adjustment has normally been
carried out already; so this procedure is not necessary.
After installation work is complete, double-check the output voltage by connecting a tester, etc. in AC
voltage measurement mode to the output monitor terminals while the antistatic electrode is
connected. Make adjustments if necessary.
AC output voltage switching
This product can switch between AC output voltages.
Remove the top cover and operate the internal selector
switch and adjustment knobs.

5 kV: Move to the center (position 2)
7 kV: Move to the right (position 3)
