Operation
• Internal Charger (Int Chgr) – This fault message displays when the FET bridge shuts down
because the charger circuit is trying to provide maximum current, but is not detecting any current
or voltage rise to the battery bank.

• Internal NTC (Int NTC) – This fault displays when the internal NTC (Negative Temperature
Coeffi cient) sensor suddenly senses a very large but unexpected temperature change.

• Internal Relay (IntRelay) – This fault displays when the internal AC transfer relay is not
closed while charging.

• Internal Bridge (Int Brdg) – This fault message displays when the FET bridge shuts down
after the inverter has been inverting—the inverter output circuit can no longer detect any AC
output voltage or current.

5.3.4.3 Internal Fault Messages
The inverter continually monitors several internal components. If a condition inside the inverter
occurs that does not allow proper operation, the inverter shuts down to protect itself. To clear
these “internal” faults, the inverter will require an inverter reset.
Remedy: Perform an inverter reset (see Section 6.2). After resetting the inverter,
press the ON/OFF INVERTER button to turn the inverter on and verify the fault has
cleared. If the internal fault remains, the inverter will require repair at a Magnum
Energy Authorized Service Center.
