Basic Functional Test
976-0043-01-02 4–5
Confirming Inverter OperationTo confirm that the inverter is operating c orrectly:
◆Disconnect the AC input power by turning the input AC power
breaker off or unplugging the AC power cord.
• The inverter should transfer to inverter mode immediately. This
will be indicated by the INVERT (yellow) LED illuminating.
• The inverter will begin to produce an low audible “buzz” as it
takes power from the batteries and uses it to power the loads.
• The loads should continue to operate uninterrupted.
This completes the functional test. If all tests pass, th e inve rter is rea dy for
use. If any of the inverter’s internal set points are to be adjusted, consult
the programming chapters of this manual.
