Appendix C – Preventative Maintenance

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 switch is a small momentary type

pushbutton which operates by lightly pressing and releasing. Be

careful not to apply too much force when pushing or the switch

might break.

Performing a Power Reset (i.e., hard reset)

To perform a power reset (also known as a "hard reset"):

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, do not remove the DC negative

connections to the inverter or any accessory until all positive

battery connections have been disconnected. This will prevent

damage to the inverter or to any network connected accessory.

Ensure the inverter and the remote are disconnected from all AC and

DC power.

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.
