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
• Securely connect the black negative (-) cable lead to the negative (-) terminal of the battery or power source
• Connect a 2.00mm^2 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 × 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. 345Watt / 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
• 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 amphours (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: Hold ON/OFF Button on the front panel for 3 seconds. The GREEN LED indicator light will light verifying the inverter is receiving power

Turn OFF the inverter: Hold ON/OFF Button on the front panel for 3 seconds

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, hold the ON/OFF Button for 3 seconds
• Turn the appliance ON.

To disconnect, reverse the above procedure

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 230 volt 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 (0.75mm^2) wire, using as short a length as possible.

Protective Features

Low Voltage Alarm (Yellow 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.

Over-Voltage Protection (Yellow LED on Inverter) - The Inverter will automatically shut down when the input voltage exceeds 15.8 ± 0.5V volts DC

Overload Protection (Yellow 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 yellow 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^ 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.
