3. Insulation resistance mesurement (Only U.S.A.
model)
Connect the insulating-resistance tester between the plug

of power supply cable and the terminal GND on the
back panel.
Specifications; More than IOMfl at 500V.

. Voltage selector (rear panel)

Worldwide models are equipped with a voltage selector
to conform with local power supplies. Be sure to set this
switch to match the voltage of the power supply in your
area before turning the power switch on. Voltage is
changed by sliding the groove in the switch with a screw-
driver or similar instrument to the up or down position.
Confirm that the switch has been moved all the way to
the up or down before turning the power switch on. If
there is no voltage selector switch on the unit you have
purchased, it can only be used in areas where the power
supply voltage is the same as that of the unit.
