Q. Why does it damage the inverter if the battery leads are reverse-connected?
A. Your inverter uses sophisticated electronics to convert DC battery power to AC mains
power. If you accidentally connect the inverter to the battery incorrectly (reverse
polarity) a large current will be drawn by the inverter which will blow the protection
fuse. As this occurs some of the high current could damage sensitive electronic
components. Because of this risk it is important to always double-check the battery
polarity before making any connections.
Q. How do I check or change the fuses?
A. Intelli-Wave inverters contain internal fuses and should only be checked or replaced
by a qualified electrical appliance repairer.
THE DC SUPPLY MUST BE DISCONNECTED BEFORE ANY REPAIR, THEN TURN THE
ON/OFF SWITCH OF THE INVERTER "ON" TO DISCHARGE THE CAPACITORS.
Q. Why does the fan only operate sometimes?
A. Intelli-Wave inverters feature a temperature controlled automatic cooling fan that only
operates when needed. This allows the inverter to run very quietly for most of the time.
Q. Can I run laptop computers and other sensitive electrical appliances?
A. Yes. Intelli-Wave's pure sine wave output is suitable for medical equipment and
sensitive electrical appliances. They allow you to watch television without static,
operate computers and gaming consoles and run fluorescent lights.
