(3) Precaution in load connection

①

Be sure to provide a switch for turning the load ON and OFF between the

output terminal block and the load.

Note that the use of the breaker of the machine for turning the load ON and

OFF may result in breaker failure.

②

In connecting the load, be sure to stop the engine and turn OFF the breakers on

the control panel.

③

Don't contact the connecting cable to the output terminal of other phase on the

output terminal block.

④

When the load connection is finished, close the cover of output terminal and

tighten by the bolts.
