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
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. Prior to
performing any reset, ensure all AC power (utility, generator, shorepower) is removed from the
inverter’s input.
CAUTION:
If AC is connected while performing an inverter reset, damage may occur.
4.4.1
Performing an Inverter Reset
To perform an inverter reset (also known as a “soft reset”):
1. Press and hold the Power ON/OFF pushbutton (see Figure 4-1) for approximately
fi
fteen (15)
seconds until the Charging/Inverting Status LED comes on and
fl
ashes rapidly.
2. Once the rapid
fl
ashing has begun, release the Power ON/OFF pushbutton. The Status LED will
go off after the pushbutton is released.
3. After the inverter reset is completed, press the ON/OFF pushbutton to turn the inverter on.
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 an 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. Open the inverter’s positive DC disconnect (or disconnect the positive battery cable to the
inverter).
CAUTION:
If removing all battery power (positive and negative) to the inverter, remove
the positive battery connections
fi
rst, then remove the DC negative connections to the
inverter or to any accessory. This will prevent damage to the inverter or to any network
connected accessory.
2. Ensure the inverter and the remote are disconnected from all AC and DC power (the remote
display will be blank).
3. 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.
