between terminals.
Prohibition
Turn “OFF” the breaker before removing the front panel and cabinet, otherwise an electric
shock is caused by high voltage resulted in a death or injury.
During operation, a high voltage with 400V or higher of circuit (
∗
) at secondary circuit of the
high-voltage transformer is applied.

electric insulator.
∗
:# For details, refer to the electric wiring diagram.

high-voltage capacitor terminals.
If discharge is not executed, an electric shock is caused by high voltage resulted in a death or injury.
After turning off the breaker, high voltage also keeps to apply to the high-voltage capacitor.
Do not turn on the breaker under condition that the front panel and cabinet are removed.
