Misusing or incorrectly connecting the EN548 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.

WARNING
Keep children away from the EN548. The
inverter generates the same potentially lethal AC
power as anormal household wall outlet.

Warnings and Cautions
The EN548 housingmaybecome uncomfortably
warm, reaching140°F(60°C) under extended high
power operation. During operation, keep away
from materials that may be aected by high
temperatures.
Do not use the EN548 in the presence of
flammable fumes or gases, such as in the bilge of a
gasoline powered boat, ornear propane tanks. Do
not use the EN548 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.
Use cautionwheninsertingan AC plug into the
three-prongACoutlet.The prongs of an AC plug can
become bent from misuse.If an AC plug is
improperly inserted into theAC outlet, abent prong
can slip outside the inverter and become ashock
hazard.
Grip theinverter carefullywhen inserting or
removingan AC plug.Keepyour ngers clear of the
AC outlet. Ensure that your ngers do not contact
the prongsof an AC plug when the plug is
partiallyinside theinverter.
WARNING: Shock hazard

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. 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

rechargeable flashlights, some rechargeable
shavers, and night lights that are plugged
directly into an AC receptacle to recharge.
CAUTION
Do not connect live AC power to the EN548
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 EN548
•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: Output non-sinusoidal
Some chargers for small nickel-cadmium batteries
can be damaged if connected to the EN548
Do not use the inverter with the following
appliances:
•Small battery-operated appliances like

Additional Safety Guidelines
•Do not insert foreign objects in the
outlets or other openings.
•Never connect the inverter to power utility AC
distribution wiring.
•Do not use the in temperatures
over 100° F (40° C).
•Do not expose the to water, rain,
snow, or spray.
Failure to follow these safety guidelines may cause
personal injury and/or damage to the EN548
It may also void your product warranty.
•Overload protection with automatic shutdown
•Low battery voltage shutdown
•High-input voltage protection with automatic
shutdown
•Overheat protection with automatic shutdown
•Output short circuit protection.

EN548
The
EN548
AC output waveform, called
“modified sine wave” is designed to function
similarly to the sine wave shape of utility power.
Most devices are not affected by a "modified sine
wave", you may need to consult with the manufacturer
of the device you wish to run prior to connection
with inverter.
Through its AC outlet, the is capable
of powering most 120V AC products that use
500W or less. The
EN548
can also power or
chargemost consumer electronics that have
USB power ports.
5.Using the Inverter

8
1. Plug a DC cable into the DC cable port on the
EN548 and connect to a 12V cigarette lighter
receptacle.
2. Plug the device you want to operate into the
EN548
3. When the inverter is not in use, unplug it from the
12V outlet to prevent slight discharge of the
battery.

9
1.Whenproperly connected to a 12V outlet, the
light will glow GREEN, 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 EN548 senses that the voltage
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
EN548 is powering.
