Performing an Inverter Reset
To perform an inverter reset (i.e., “soft reset”):
1. Remove all AC power (utility or generator power) to the inverter.
2. Press and hold the inverter’s Power ON/OFF pushbutton (see Figure 6-1)
for approximately
fi
fteen (15) seconds—until the inverter’s Charging/
Inverting Status LED comes on and
fl
ashes rapidly.
3. Once the rapid
fl
ashing has begun, release the Power ON/OFF
pushbutton. The Status LED will go off after the button is released.
4. After the inverter reset is completed, press the inverter’s Power ON/OFF
pushbutton to turn on the inverter.
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.
Info:
All adjustable inverter/charger settings in the ME-RC (except
for SHORE menu’s
Shore Max
and SETUP menu’s
08 Screen Setup
settings (which revert back to default) are saved in non-volatile
memory and are preserved until changed—even if an inverter reset
is performed, or if all power to the remote or inverter is removed.

2. Press and hold the Power ON/
OFF pushbutton for 15 seconds.
3. Watch the Charging/Inverting
Status LED, after approximately 15
seconds it should come on and flash
rapidly to indicate the inverter has
reset. The Status LED will go off
after the pushbutton is released.
1. Ensure all AC power (i.e.,
shorepower or generator) is
removed from the inverter’s input.
6.3
Performing a Power Reset
To perform a power reset (i.e., “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 and the remote are disconnected from all AC and DC
power (the remote display will be blank).
4. After the inverter 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.
