PRECAUTIONS

l. Replacing the fuses
For continued protection against risk fire, replace only with same type and same rating fuse,

CIRCUIT NO. PART NO. DESCRIPTION

F90] 252052 7A ST-o. Primary fuse (120V, lZlW/ZZOV model)

F901 252075 25A»SE-EAK. Primary fuse (230V model)

F902 252077 4A-SE-EAK, Primary fuse (230V. 240V. 120V/220V model)

Insulation resistance mesurement (Only U.S.A. model)
Connect the insulatingeresistance tester between the plug of power supply cable and the terminal GND on the back panel. Specifications;
More than 10 M9 at 500Vl

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
ot'the power supply in your area before turning the power switch on, Voltage is changed by sliding the groove in the switch with a screwdriver
to the up or down. Confirm that the switch has been moved all the way to the up or down before turning the power switch on. Models without
a voltage selector can only be used in areas where the power supply is the same as that of the unit.
