Figure 5-19, FET Overload Fault

• FET Overload - This fault message indicates the inverter/charger has
shut down because the internal FET's (Field Effect Transistor's) have quickly
exceeded a safe operating temperature. When the FET's have cooled, the
unit will require a manual restart to resume operation.
Remedy: If the fault continues to occur, disconnect all the inverter's
AC output wires and reset the inverter (see section 6.2). If this fault
does not clear after doing a reset, the inverter may require service.

Figure 5-20, Breaker Tripped Fault

• Breaker Tripped - The inverter has detected that the AC input breaker
on the inverter/charger has opened due to excess current flow 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 AC HOT OUT 1 exceed the
current rating of this circuit breaker.

Figure 5-21, Unknown Fault

• Unknown Fault - This fault message displays when the inverter/charger
has sent a fault code that cannot be determined by the remote.
Remedy: Call the Technical Support department at Magnum Energy
for assistance to help determine and understand the actual fault
status.
