Warnings & Caution
Use of the device in life support applications where failure of the device can
reasonably be expected to cause the failure of the life support equipment or to
significantly affect its safety or effectiveness is not recommended. Do not
use the device in the presence of a flammable anesthetic mixture with air,
oxygen or nitrous oxide, and also not near flammable materials, fumes or
gases. Since the device requires adequate ventilation during operation, do
not block fan or cooling vents and do not cover the device. Do not operate
near car heating vents or in direct sunlight. Keep the device dry at all times
and disconnect when not in use. Turn OFF connected equipment before (!)
starting your engine. DO NOT plug a surge protector, line conditioner or UPS
system into the device. If you attach AC extension cords, use the heaviest
practical gauge. Before connecting a battery charger or adapter, check its
manual to make sure that the technical specifications of the device (including
output waveform) fall within the recommendations of the external battery
charger or adapter.

Determine Battery Capacity
Battery type and battery size strongly affect the performance. Therefore, you
need to identify the type of loads your inverter will be powering and how much
you will be using them between charges. Once you know how much power
you will be using, you can determine how much battery capacity you need.
Technaxx recommends that you purchase as much battery capacity as
possible.
CAUTION: Risk of inverter damage.
The inverter must only be connected to a battery that has a nominal output
of 12V.
Not operate if connected to a 6/24V battery.
Voltage converter installation
Install the power inverter with suitable screws (not included):
in sturdy and even locations
on clean, dry and non-flammable surfaces,
in well ventilated areas.
Please be sure not to cover the vents.
Connecting the inverter
This Inverter has two DC cable connections, one positive and one negative.
The order of steps in the following procedure minimizes the danger of sparking
near the battery bank.
Prepare all cable set ends with ring terminals at the battery ends.
Select the OFF position on the inverter.
Remove the red positive(+) screw connector cap.
Slide the red positive(+) cable lead onto the red positive(+) screw connector
stud. Tighten the screw connector cap securely.
Remove the Black negative(-) screw connector cap.
Slide the Black negative(-) cable lead onto the Black negative(-) screw
connector stud. Tighten the screw connector cap securely.
Securely connect the red positive (+) cable lead to the positive (+) terminal
of the battery or power source.
Page 6
Securely connect the black negative (-) cable lead to the negative (-)
terminal of the battery or power source.
Connect a 0.75mm² wire or larger insulated wire between the chassis
ground connector on the Inverter and a clean electrical grounding point on the
vehicle. This will minimize possible electrical noise interference when using
TVs or radios.
Note: Sparking is normal for first connection.
Operation
Before using the power inverter determine your
equipment’s total watts!
Do not connect more watt than the Output Power (maximum continuous
watt) of the device ( see technical specifications).
Determine Total Wattage Required, Watt ratings are usually listed in
equipment manuals or on nameplates. If your equipment is rated in Amp,
multiply that number times AC utility voltage to determine watts.
(Mathematic example: a drill requires 1.5A 1.5A x 230Volt = 345Watt. No
problem to use the drill.)
Remember the vehicle‘s battery will be discharged when the vehicle is not
running.
To Determine DC Battery Amps Required, divide the total wattage
required (from above) by the nominal battery voltage to determine the DC
amps required. 345 Watt : 12V = 28.75A DC.
To Estimate Battery Amp-Hours Required multiply the DC amps required
(from above) by the number of hours you estimate you will operate your
equipment exclusively from battery power before you have to recharge your
batteries with utility- or generator-supplied AC power. Compensate for
inefficiency by multiplying this number by 1.2. This will give you a rough
estimate of how many amp-hours of battery power (from one or several
batteries) you should connect to your inverter/charger.
28.75A DC x 0.5h runtime x 1.2 inefficiency rating = 17.25 amp-hours.
Page 7
To Estimate Battery Recharge Required given Your Application You must
allow your batteries to recharge long enough to replace the charge lost during
inverter operation or else you will eventually run down your batteries.
To estimate the minimum amount of time you need to recharge your batteries
given your application, divide your required battery amp-hours (from above) by
your Inverter/Charger’s rated charging amps (depending on the ON/OFF
settings). 17.25 amp-hours / 40A inverter/charger rating = 0.43h recharge
Operation
Turn ON the inverter:
Turn ON/OFF switch on the front panel. The GREEN LED indicator light will
light verifying the inverter is receiving power.
Turn OFF the inverter:
Turn ON/OFF switch on the front panel. When you have confirmed that the
appliance to be operated is turned off, plug an appliance cord into one of the
230V AC outlets on the front panel of the inverter.
Turn Inverter ON/OFF Switch to the ON position
Turn the appliance ON.
To disconnect, reverse the above procedure.
Power switch can be off when you only use the USB output ports.
Note: If you are going to operate several loads from the inverter, turn them on
separately after you have turned the inverter on. This will ensure that the
inverter does not have to deliver the starting current for all the loads at once.

Using the Inverter to Operate a TV or Audio Device
The inverter is shielded and filtered to minimize signal interference. Despite
this, some interference may occur with your television picture, especially with
weak signals. Below are some suggestions to try and improve reception.
Make sure the television antenna produces a clear signal under normal
operating conditions (i.e. at home plugged into a standard 230V AC wall
outlet). Also, ensure that the antenna cable is adequately shielded and of
good quality.
Try altering the position of the inverter, antenna cables, and television power
cord. Add an extension cord from the inverter to the TV so as to isolate its
power cord and antenna cables from the 12 volt power source. Try coiling the
television power cord and the input cables running from the 12 volt power
source to the inverter.
Affix one or several “Ferrite Data Line Filters” to the television power cord.
Ferrite Data Line Filters can be purchased at most electronic supply stores.
Try grounding the inverter with a minimum (0.75mm²) wire, using as short a
length as possible.
Protective Features
Low Voltage Alarm (Red LED on Inverter)
This state is not harmful to the Inverter, but could damage the power source.
The Inverter shuts off when the input voltage drops to 10.5 volts and an
audible alarm sounds same time. When ample power is supplied, the Inverter
may then be turned back on.
Over-Voltage Protection (Red LED on Inverter)
The Inverter will automatically shut down when the input voltage exceeds
15.8±0.5V DC.
Page 9
Overload Protection (Red LED on Inverter)
The Inverter will automatically shut down if the continuous draw exceeds its
maximum wattage rating. When the Inverter is at or near maximum output, an
alarm will sound. When the alarm sounds you need to disconnect the device(s)
to bring the Inverter output down to an acceptable level.
If you continue to use the Inverter at or near the maximum output, it will
eventually overheat and shut down. If you exceed the maximum Inverter
output, the alarm will sound and the Inverter will automatically shut down. The
red fault indicator will light and the alarm will continue to sound. The Inverter
must be reset after an overload condition.
Temperature Protection
The Inverter is equipped with a cooling fan. Depending upon the load output
and the temperature of the Inverter, the cooling fan will turn on and off as
required to cool the Inverter if needed. If the temperature reaches
approximately 80°C the Inverter will shut down automatically. Turn off the
Inverter and allow it to cool for a minimum of 15 minutes. Before starting up
again, verify the total wattage of the devices being powered.
To Reset the Inverter
1. Turn off the Inverter using the ON/OFF switch on the Inverter, depending
upon how the Inverter was controlled.
2. Unplug all devices.
3. Turn the Inverter back on using the ON/OFF switch on the Inverter. Before
devices are reconnected, verify the total wattage of the devices to ensure they
are less than the rating of the Inverter.
