5.0 Operation
Remedy:
If the fault continues, disconnect all the inverter’s AC
output wires and reset the inverter (see Section 6.2). If the fault
does not clear after the reset, the inverter may require service.
Breaker Tripped
- The AC input breaker on the inverter/charger has
opened due to excess current
fl
ow thru the inverter to the AC loads.
Remedy:
After reducing the AC loads, push in the inverter’s AC
input circuit breaker to reset and resume operation.
Info:
While in Charger mode, the inverter’s AC input breaker
could nuisance trip if the loads on the inverter’s output exceeds
the current rating of the inverter’s input circuit breaker.
Unknown Fault
- This fault message displays when the inverter/charger
has sent a fault code that cannot be determined by the router.
Remedy:
Call the Technical Support department at Magnum
Energy for assistance in determining and understanding the
actual fault status.
Tfmr Overtemp
- This fault message displays when the transformer
causes the inverter to shut down to protect the internal power transformer
from damage. Once the transformer cools down, the inverter automatically
restarts and resumes operation.
Remedy:
If the fault occurs while inverting, reduce the load
on the inverter. If while charging, turn down the charge rate.
If this fault occurs often, ensure the inverter is in a cool loca-
tion, has adequate ventilation, and the internal cooling fans are
operational.
