PRECAUTIONS
1. Replacing the fuses
For continued protection against risk fire, replace only with same type and same rating fuse.
CIRCUITNO. PARTNO. DESCRIPTION
F901 252051 6A ST-6, Primary fuse (120V, 120V/220V models)
F902 252076 or 3. 15A-SE-EAK or
252076CC 3. 1SA-SE-EAK Primary fuse (220V, 240V, 120V/220V models)
2. 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 10 MQ at 500V.
3. 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 screwdriver to the right or left. Confirm that the switch has
been moved all the way to the right or left 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.
