energizerpower.com/au
2. Important Safety Information
Misusing or incorrectly connecting the ENA548 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.
Caution: Identify conditions or practices that may
damage the unit or other equipment.
WARNING
Keep children away from the ENA548. The
inverter generates the same potentially lethal AC
1
power as a normal household wall outlet.

Warnings and Cautions
The ENA548 housing may become uncomfortably
warm, reaching 60° C under extended high power
operation. During operation, keep away
from materials that may be affected by high
temperatures.
Do not use the ENA548 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 ENA548 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
be 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.

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
3

CAUTION: Output non-sinusoidal
Some chargers for small nickel-cadmium batteries
can be damaged if connected to the ENA548
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 ENA548
AC outlets. This will damage the inverter,
and the damage is not covered by warranty.
Do not connect any AC load which has its neutral
conductor connected to ground to the ENA548

Additional Safety Guidelines
•Do not insert foreign objects in the
ENA548 outlets or other openings.
•Never connect the inverter to power utility AC
distribution wiring.
•Do not use the ENA548 in temperatures over
40° C.
•Do not expose the ENA548 to water, rain,

5. Using the Inverter
Through its AC outlet, the ENA548 is capable
of powering most 240V AC devices that consume
500W or less. The ENA548 can also power or
charge most consumer electronics that have
USB power ports.
The ENA548 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.
7

1. Connect the DC cable port on the ENA548
and connect to a 12V cigarette lighter
receptacle.
2. Plug the device you want to operate into
the ENA548
3. When the inverter is not in use, unplug it from
the 12V outlet to prevent slight discharge of
the battery.
4. When using a device which consumes more
than 120W, connect the alligator clip cables
to the ENA548 and connect the clip end
directly to a 12V battery.
8

6. Inverter Operation
1. When properly 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 depletes, the voltage will start falling.
When the ENA548 senses that the input DC voltage
has dropped to 10.5V, the inverter automatically
shuts down and the light will turn RED, indicating a
fault. This prevents the battery from being
damaged. Turn off any devices that the ENA548 is
powering.
9

Important: Vehicle batteries are designed to provide
brief periods of very high current needed for engine
starting. They are not intended for constant deep
discharge. Regularly operating the ENA548 from a vehicle
battery until low-voltage shutdown will shorten the life of
the battery.
•If an AC product rated higher than 500W is
plugged into the ENA548, the inverter will
shut down. The LED light will alternate from
GREEN to RED continuously.
•If the ENA548 exceeds a safe operating
temperature, due to insufficient ventilation or a
high-temperature environment, it automatically
shuts down. The RED FAULT light comes on.
•Should a defective battery charging system cause
the battery voltage to rise to dangerously high
levels, the ENA548 automatically shuts
down. The RED FAULT light comes on.
10

CAUTION
Although the ENA548 incorporates protection
against over-voltage, it may still be damaged
if the input voltage exceeds 16 V.
•In the event of an overload, low battery voltage or
overheating, the ENA548 automatically shuts
down.
Battery Operating Time
Operating time will vary depending on the charge
level of the battery, its capacity and the power level
drawn by the particular AC load, USB load, or
combination of both.
When using a vehicle battery as a power source, it is
strongly recommended to start the vehicle every hour
or two to recharge the battery before its capacity drops
too low. The ENA548 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.
11

Interference with Electronic Equipment
Generally, most AC products operate with ENA548
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 and AM-FM radios
have inadequate internal power supply filtering and
will “buzz” slightly when powered by the ENA548
Generally, the only solution is an audio product
with a higher quality filter.
Television interference
The ENA548 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
ENA548 and the TV, antenna and
cables.
•Adjust the orientation of the
ENA548 television, antenna and
cables.
•Maximize TV signal strength by using a better
antenna and use shielded antenna cable where
possible. 12
