600 / 630 / 660 / 690 V
Check that the incoming voltage level is equal to
inverter voltage AC output.
Close Auxiliary service transformer primary
breaker.
Check that voltage is 400 /230 V +/-10%.
Check that the Auxiliary service transformer sec-
ondary winding voltage level is 400 / 230 V.
Close Auxiliary service transformer secondary
breaker.
Check that there is no voltage before opening the
next auxiliary breaker.
Close the auxiliary breakers one at a time. and
