6. SPECIAL RECOMMENDATIONS
Unplug the AC inverter when it is not in use and when starting the vehicle's motor.
If the AC inverter makes a beeping sound : switch off your appliance, unplug the inverter and
restart your vehicle's engine. The beeping sound is simply the battery-low indication, warning
you that the voltage of your battery is getting low. Your inverter will shut down automatically if
you do not restart your engine and continue to use your inverter. This will leave your vehicle's
battery at about 10.5VDC (12V-version) / 21VDC (24V-version), enabling you to start your
engine and resume operation of the inverter. It also eliminates the possibility of being
stranded with a dead battery.
To avoid over-discharging the battery, it is advisable to let your engine run for 10 to 20
min. for every 2-3 hours of using the AC inverter. This allows the battery to recharge.
Please remember to connect the "+" wire to the "+" terminal and the "-" wire to the "-"
terminal if you choose to use an adapter for a direct connection between the AC inverter
and the battery terminals. IF YOU CONNECT THE WIRES TO INCORRECT TERMINALS,
THE POLARITY WILL BE REVERSED AND THIS WILL DAMAGE THE INVERTER.
REVERSED POLARITY WILL INSTANTLY VOID YOUR INVERTER'S WARRANTY.
Please remember to disconnect the AC inverter before connecting the battery charger in
order to replenish your battery. Failure to disconnect the inverter prior to connecting a
charger may result in an input spike that will damage the inverter.
CONNECTING THE INVERTER'S INPUT TO A BATTERY CHARGER WILL VOID THE
WARRANTY AND MAY DAMAGE THE INVERTER.
Make sure the voltage never exceeds 15VDC (12V-version) or 30VDC (24V-version).
CONNECTING THE INVERTER TO A DC POWER SOURCE SUPERIOR TO 15VDC
(12V-version) or 30VDC (24V-version) WILL VOID THE WARRANTY AND MAY DAMAGE
THE INVERTER. THE INVERTER WILL BE SHUT DOWN AUTOMATICALLY.
Pay attention when connecting a device to a PI. The manuals of many devices list the
nominal power and NOT the startup power. The PI's are protected against overload and
this can cause the connected devices to start up with difficulty or not at all. Read the
manual of the device to know the peak power or consult the manufacturer.
The PI of the type ...MN/...BN has a modified sine output (viz. square wave). Read the
manual of your PI. This means that a 300W device may experience difficulties starting up
or may not work at all when connected with e.g. a PI300...N.
7. ADDING EXTENSION CORDS
We recommend that the buyer refrain from using an extension cord between the
DC power source and the inverter's DC input. Connecting an extension cord to the
DC input will create a voltage drop which, in turn, entails reduced efficiency.
Instead, we recommend using an extension cord to link the AC output and the AC
appliance. You can use up to 100ft (30m) of high-quality extension cord. A longer
cord may result in reduced power.
