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 15 seconds until the 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 pushbutton is released.
4. Press the Power ON/OFF pushbutton to turn on the inverter.
Some older inverter models do not allow an inverter reset. If the inverter
reset fails, 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-MR 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.

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 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.

1. Ensure all AC power
(i.e., shorepower or generator) is
removed from the inverter's input.
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.
