4. As the battery pack becomes nearly discharged, or “empty”, a
low voltage warning will sound. This will give you time to shut
down a computer, for example. If this warning is ignored, the
inverter will switch off automatically a few minutes later to
prevent battery damage. See below - Automatic Protection:
Overload, Overheating and Low Battery for details.
5. Fully recharge xPower1500’s battery pack as soon as possible
after each use. See Section 7.
Automatic Protection: Overload, Overheating
and Low Battery
xPower1500 has built-in protection against output overload and from
overheating. If an AC product rated higher than 1350 watts (or which
draws excessive surge power at start up) is connected, or if the
inverter exceeds a safe temperature, it will automatically shutdown.
The green POWER light will go off and the red FAULT light will
switch on. To reset, unplug the product and turn the AC Outlets
Switch off for 5 seconds, then turn it back on. Normal operation
should resume. If not, turn the AC Outlets Switch off again and allow
xPower1500 to cool for several minutes. While AC power is off, press
the Battery Status Switch to make sure the charge level is sufficient.
If the battery pack is allowed to discharge excessively, damage may
occur. To prevent this, xPower1500 has a built-in audible warning that
alerts you when the battery pack is nearly discharged and that
recharging is needed. If this warning is ignored, xPower1500 will
automatically switch off the AC Outlets and the red FAULT light will
illuminate when the battery pack reaches “empty”. The FAULT light
will remain on until the AC Outlet’s Switch is turned off. Promptly
recharge xPower1500 to help maintain the internal battery pack. See
Section 7.
Interference with Electronic Equipment
Buzzing Sound in Audio Systems
Some inexpensive stereo systems and “boom-boxes” will emit a
buzzing sound from their loudspeakers when operating from the
AC output of xPower1500. This is because the power supply in
the equipment does not adequately filter the modified sine wave
produced by xPower1500. Unless the stereo can be operated
directly from xPower1500’s 12-volt DC Power Socket, the only
solution is a sound system with a higher quality internal power
filter.

8. Take the other end of the jump-start cables and connect the black
negative (-) clamp to xPower1500’s negative High Power DC
Terminal (black). You are now ready to start the engine.
9. If the vehicle fails to crank, disconnect the jump-start cables in
reverse order of steps 5-8. Ensure that the contact areas are
clean, then repeat steps 5 through 8.
10. After the vehicle is started and while the cables are still
connected, it is a good idea to run the motor at fast idle for 5
minutes to fast-charge xPower1500’s battery pack. After
recharging, remove the jump-start cables in the reverse order of
steps 5-8.
Jump-Starting via a Vehicle’s Lighter Plug
Socket
The following simple procedure is often sufficient to start a vehicle
when its battery has sufficient power to “crank the engine” slightly,
but not start it.
1. Connect your vehicle’s cigarette lighter socket to xPower1500’s
DC Power Socket using the DC Charging Cable. You may need to
switch the ignition key to the “accessory” position to supply
power to the lighter socket. Be sure to also turn off all
accessories that may be running from the vehicle’s battery.
2. Wait 15 minutes while xPower1500 partially charges your
vehicle’s battery, then remove the DC Charging Cable before
attempting to start the engine.
3. If your vehicle does not start, attempt to jump-start as described
in the previous section - Jump-Starting Directly to the Battery.
CAUTION:
Do not attempt to start your vehicle while the DC
Charging Cable is connected to the vehicle’s 12-volt outlet or
lighter socket. Remove the DC Charging Cable first, then start
your vehicle. This will prevent the fuse protecting the vehicle’s
12-volt outlet from blowing.
