CAUTION

(Ref. page)

• Verify that the inverter rated voltage coincides with the

AC power supply voltage.

Failure to observe this caution can result in personal injury

or a fire.

• Do not perform a withstand voltage test of the inverter.

It may cause semi-conductor elements to be damaged.

• To connect a braking resistor, braking resistor unit or

braking unit, follow the procedures described in

this manual.

Improper connection may cause a fire.
