This unit can operate either on AC110-120V or AC220-240V.
Connect the primary side of the transformer to the CN6 connector (for
AC220-240V) or the CN7 (for AC110-120V) on the main circuit board (A)
after confirming which power voltage you use. This unit is originally set
for CN6 (AC220-240V) before shipment.
(Note) If the combination of the power voltage and the transformer
primary-side selection is incorrect, the unit may be damaged.
Turn off the main power supply before changing the connector.
Because this is a high-voltage circuit, there is a danger of electric
shock.
