Maintenance and Troubleshooting
Figure 4-1, Performing an Inverter Reset
1. Press and hold the Power ON/OFF pushbutton.
2. Watch the Charging/Inverting Status LED, after
approximately 15 seconds it should come on and
fl
ash rapidly to indicate the inverter has reset.
The Status LED will go off after the pushbutton
is released.
4.4 Resetting the Inverter
Under some fault conditions (e.g., an internal fault), the inverter will need to be reset.
4.4.1
Performing an Inverter Reset
To perform an inverter reset (also known as a “soft reset”):
1. First, 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 (see Figure 4-1) for approximately ten (10)
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. After the inverter reset is completed, press the ON/OFF pushbutton 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 Section 4.4.2. 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.
4.4.2
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 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.
