Maintenance and Troubleshooting
1. Press and hold the Power
ON/OFF pushbutton.
2. Watch the Charging/Inverting
Status LED, after approximately
15 seconds it should come on

inverter has reset. The Status LED
will go off after the pushbutton is
released.

4.4 Performing an Inverter Reset
Certain faults require the inverter to be reset. To perform an inverter reset (also known as a soft
reset), press and hold the Power ON/OFF button (see Figure 4-1) for approximately fi fteen (15)
seconds until the Charging/Inverting Status LED comes on and fl ashes rapidly. Once the rapid
fl ashing has begun, release the Power ON/OFF button. The Status LED will go off after the button
is released.
After the inverter reset is completed, press the Power ON/OFF button to turn the inverter ON.
Some older inverter models do not allow an inverter reset. If the inverter reset fails, you will need
to perform a power reset using the procedure below. In either case, if an internal fault does not
clear, the inverter will require repair at a Magnum Authorized Service Center (ASC).
Info: The Power ON/OFF pushbutton is a small momentary type switch which operates
by lightly pressing and releasing. Be careful not to apply too much force when pushing
or the switch might break.
4.5 Performing a Power Reset
To perform a power reset (also known as a hard reset):
1. Remove all AC power (utility or generator power) to the inverter.
2. Open all the inverter DC disconnects (or disconnect the positive battery cable to the inverter).
3. Ensure the inverter(s) and the remote are disconnected from all AC and DC power (the
remote display will be blank).
4. After the inverter(s) has been disconnected from all power for 30 seconds, reconnect the
inverter DC disconnects (or reconnect the positive battery cable) and resume operation.
Info: If DC disconnects are not used, there may be a momentary spark when the
positive battery cable is connected to the inverter’s terminal. This is normal and
indicates that the inverter’s internal capacitors are being charged.
