2 Important Safety Information

Misusing or incorrectly connecting theXR400/750
may damage the equipment or create hazardous
conditions for users. Read the following safety
instructions and pay special attention to all Caution
and Warning statements in the guide.
Warnings identify conditions that may result in
personal injury or loss of life.
Cautions identify conditions or practices that may
damage the unit or other equipment.

WARNING

Keepchildren away from the XR400 / XR 750. The

nvertergenerates the same potentially lethal AC

i
power as a normal household wall outlet.

1

Warnings and Cautions

The XR400 / XR750 housing may become

uncomfortably warm, reaching 140° F (60° C) under
extended high power operation. During operation,
keep it away from materials that may be affected by
high temperatures.

Do not use the XR400 / XR750 in the presence of

flammable fumes or gases, such as in the bilge of a
gasoline powered boat, or near propane tanks. Do

not use the XR400 / XR750 in an enclosure

containing automotive-type, lead-acid batteries.
These batteries, unlike sealed batteries, vent
explosive hydrogen gas, which can be ignited by
sparks from electrical connections.

WARNING: Shock hazard

Use caution when inserting an AC plug into the
three-prong AC outlet. The prongs of an AC plug
can become bent from misuse. If an AC plug is
improperly inserted into the AC outlet, a bent prong
can slip outside the inverter and become a shock
hazard.
Grip the inverter carefully when inserting or
removing an AC plug. Keep your fingers clear of
the AC outlet. Ensure that your fingers do not
contact the prongs of an AC plug when the plug is
partially inside the inverter.

2

CAUTION: Risk of Fire.

Do not replace any vehicle fuse with a rating higher
than recommended by the Vehicle Manufacturer.
Ensure that the electrical system in your vehicle
can supply this product without causing the vehicle
fusing to open. This can be determined by making
sure the fuse in the vehicle which protects the outlet is
rated higher than 8 amperes. Information on the
vehicle fuse rating is typically found in the vehicle
operator’s manual. If a vehicle fuse opens repeatedly,
do not keep on replacing it. The cause of the overload
must be found. On no account should fuses be
patched up with tin foil or wire as this may cause
serious damage elsewhere in the electrical circuit or
cause re.

2

CAUTION: Output non-sinusoidal

Some chargers for small nickel-cadmium batteries

can be damaged if connected to the XR400 / XR750

Do not use the inverter with the following
appliances:

• Small battery-operated appliances like
rechargeable flashlights, some rechargeable
shavers, and night lights that are plugged
directly into an AC receptacle to recharge.

• Battery chargers used in hand power tools.
These chargers display a warning label stating
that dangerous voltages are present at the
charger battery terminals.

CAUTION

Do not connect live AC power to the XR400 / XR750
AC outlets. This will damage the inverter,
and the damage is not covered by warranty.
Do not connect any AC load that has its neutral
conductor connected to ground to the

XR400 / XR750

Additional Safety Guidelines

• Do not insert foreign objects in the
XR400/750 outlets or other openings.

• Never connect the inverter to power utility AC
distribution wiring.

• Do not use the
over 100° F (40° C).

• Do not expose the
snow, or spray.

Failure to follow these safety guidelines may cause
personal injury and/or damage to the

CAUTION: Reverse polarity damage

When plugging in the DC cable, ensure that the plug

aligns with the DC cable port. Failure to do so will

result in reverse polarity and a blown fuse.

1. Plug a DC cable into the DC cable port on the

XR400/750 and connect to a 12V battery.
Observe correct polarity.

2. Plug the device you want to operate into the

XR400/750

3. When the inverter is not in use, unplug it from the

12V outlet to prevent slight discharge of the
battery.

when the
light will glow BLUE, indicating the inverter is
ready.

2. Plug the product(s) you want to operate into the

AC outlet or USB port and switch them on (if
necessary).

Operating Guidelines

• As the battery is used, its voltage begins to fall.

When the XR
at its DC input has dropped to 10.5V, the inverter
automatically shuts down and the light glows RED,
indicating a fault. This prevents the battery from
being damaged. Turn off any devices that the

Important:

brief periods of very high current needed for engine
starting. They are not intended for constant deep discharge.
Regularly operating the XR400/750 from a vehicle

life of the battery.

• Should a defective battery charging system cause

the battery voltage to rise to dangerously high
levels, the XR400/750 automatically shuts

CAUTION

Although the XR400/750 incorporates

protection against over-voltage, it may still be

damaged if the inputvoltage exceeds 16 V.

• In the event of an overload, low battery voltage or

overheating, the XR400 / XR750 automatically

shuts down.

Battery Operating Time

Operating time will vary depending on thecharge
level of thebattery,its capacityand thepower level
drawn by theparticular ACload, USBload, or
combination of both. With a typicalvehicle battery
and a 80Wload, anoperating timeof 4 to 5 hours or
more can beexpected.

When using a vehicle battery as apower source,it is
strongly recommended to start thevehicle everyhour
ortwotorechargethebatterybefore its capacity drops
too low. The XR400/750 can operate while the

engine is running, but the normal voltage drop that
occurs during starting of the engine may trigger the
inverter’s low voltage shutdown feature.

10

Interference with Electronic Equipment

Generally, most AC products operate with XR400/750
just as they would with household AC power.
Below is information concerning two possible
exceptions.

Buzzing sound in audio systems and radios

Some inexpensive stereo systems andAM-FM radios
have inadequate internal power supplyfiltering and
will “buzz” slightly whenpowered bythe XR400
/750. Generally,the onlysolutionis an audioproduct
witha higher qualityfilter.

Television interference

The XR400 / XR750 is shielded to minimize its

interference with TV signals. However, with weak TV
signals interference may be visible in the form of lines
scrolling across the screen. The following should
minimize or eliminate the problem:

• Increase the distance between the XR400/750
and the TV, antenna and cables.

• Adjust the orientation of the XR
television, antenna and cables.

• Maximize TV signal strength by using a better
antenna and use shielded antenna cable where
possible.

7 Troubleshooting

PROBLEM: AC product will not operate, no inverter
lights are ON.

Possible cause Solution

Battery is defective. Check battery and replace if

Loose connections. Check connections.

required.

PROBLEM: Measured inverter output is too low.

Possible cause Solution

Standard “average­reading” AC voltmeter
used to measure output
voltage, resulting in an
apparent reading 5 to 15 V
too low.

Inverter’s “modified sine
wave” output requires “true
RMS” voltmeter for accurate
measurements.

12

Possible cause Solution

Battery voltage is too low. Recharge battery.

PROBLEM: AC product will not operate, RED FAULT

light ON.

Possible cause Solution

AC product(s) connected
are rated at more than the
inverter’s continuous
power rating; overload
shutdown has occurred.

AC product is rated less
than the inverter’s
continuous power rating;
high starting surge has
caused overload
shutdown.

Use a product with a power
rating less than the inverter’s
continuous power rating.

Product exceeds inverter’s
surge capability. Use a product
with starting surge power
within the inverter’s capability.

Battery is discharged. Recharge battery.

The inverter has over
heated due to poor
ventilation and has shut
down.

Unplug inverter from DC socket
and allow to cool for 15 minutes.
Remove objects covering unit.
Move the inverter to a cooler
place. Reduce load if continuous
operation is required. Restart.
