WARNING! Do not connect the 12VDC model to a 24VDC battery. The unit will be destroyed immediately! WARNING! Operation of the inverter without a proper ground connection may result in an electrical safety hazard WARNING! Shock Hazard! Before proceeding, carefully check the AEP-700 inverter is NOT connected to any batteries and is disconnected from any electrical source. Do not connect the output terminals of the AEP-700 to an incoming source at this time.

wood particles or other filings/shavings are present that may be pulled into the unit when the cooling fan is operating. 2-3-6 Close to Batteries: Avoid excessive cable lengths but do not install the AEP-700 Inverter in the same compartment as batteries. Use the recommended wire lengths and sizes (see section 2-6). Avoid mounting the AEP-700 Inverter where it may be exposed to the gases produced by the battery. Prolonged exposure to these corrosive gases will damage the AEP-700 Inverter. 2-4 Quick Hook Up and Testing: 2-4-1 Unpack and inspect the power inverter, verifying that the power switch in the OFF position. 2-4-2 Connect the cables to the power input terminals on the rear panel of the power inverter. The red terminal is positive (+) and black terminal is negative (-). Insert the cables into the terminals and tighten the nut to securely clamp the wires . 2-4-3 Before proceeding, confirm that your cable is connected from the negative terminal of inverter to the negative output of your power source. 2-4-4 Connect the cable from the positive terminal of the inverter to the positive terminal of the power source. Make a secure connection. CAUTION! Reverse polarity connection will blow a fuse in the inverter and may cause damage. Damage caused by reverse polarity connection is not covered by our warranty WARNING! You may observe a spark when you make this connection as current may flow to charge the capacitors in the inverter. Do not make this connection in the presence of flammable fumes. Explosion or fire may result!

display shows the word “ASIAN” for twice. After that, you will hear a continuous tone from internal alarm. Finally, the AC voltage shows on the display, signaling that the inverter has done the start up. 2-4-6 Set the power switch to the OFF position; the device shut down completely. 2-4-7 Please use a power meter to accurately measure the true output R.M.S. voltage of inverter. 2-5 AC Safety Grounding: During the AC wiring installation, AC input and output ground wires are connected to the inverter. The AC input ground wire must connect to the incoming ground from your AC utility source. The AC output ground wire should go to the grounding point for your loads (for example, a distribution panel of bus chassis). 2-6. Making DC Wiring Connections: Follow this procedure to connect the battery cables to the DC input terminals on the AEP-700 Inverter. Your cables should be as short as possible (ideally, less than 10 feet / 3 meters) and large enough to handle the required current in accordance with the electrical codes or regulations applicable to your installation. Cables that are not an adequate gauge (too narrow) or are too long will cause decreased inverter performance such as poor surge capability and frequent low input voltage warnings and shutdowns. WARNING! Do not operate the power inverter without connecting it to ground. Electrical shock hazard may result. WARNING! Make sure that all DC connections are tight (torque to 9-10 foot pounds). Loose connections will overheat and could result in a potential hazard

inverter to the batteries. The longer and narrower these cables, the greater the voltage drop. Increasing your DC cable size will help improve the situation. We recommend the following cables for optimum inverter performance. Use only high quality copper wiring and keep cable length short (from 3-6 feet).

The installation of a fuse must be on positive cable. Failure to place a fuse on “+ “cables running between the inverter and battery may cause damage to the inverter and will void warranty.

To operate the power inverter, turn it on using the ON/OFF switch on the front panel. The power inverter is now ready to deliver AC power to your loads. If you are operating several loads from the power inverter, turn them on separately after the inverter has been turned on. This will ensure that the power inverter does not have to deliver the starting currents for all the loads at once. 2-7-1 Controls and indicators: The ON / OFF switch turns the control circuit in the power inverter on and off. The AEP-700 Inverter operates from an input voltage ranging from: 10.5 to 15.0 VDC for 12VDC models 21.0 to 30.0 VDC for 24VDC models 42.0 to 60.0 VDC for 48VDC models

The power inverter may overheat because it has been operated at power levels above its rating or because it has been installed in a location which does not allow it to dissipate heat properly. The power inverter will automatically restart, once the temperature has decreased.

The overload indicator indicates that the power inverter has shut itself down due to the output being overloaded. The inverter must be manually restarted. Turn off the AEP-700 inverter, correct the fault condition, then, turn the AEP-700 inverter back on. 2-8 Output Power: The AEP-700 inverter will operate most AC powered devices within its power rating. When deeming whether a microwave oven can be operated by the AEP-700 inverter, remember that the power commonly advertised for microwave ovens is the cooking power, not the power actually consumed by the microwave oven. The microwave oven will consume 40% to 100% more than its advertised cooking power. Check the rating sticker on the back of the oven to determine its actual power requirements. The AEP-700 inverter will operate small microwave oven (0.2 to 0.3 cubic foot capacity) that draws about 780 watts. It will provide 3 minutes of cooking time. Some induction motors used in refrigerators, freezers, pumps and other motor operated equipment require very high surge currents to start. The AEP-700 may not be able to start some of these motors even though their rated current requirement is within the power inverter. If the motor will not start, observe the battery voltage indicator while trying to start the motor. If the battery voltage indicator drops below 11 volts while inverter is attempting to start the motor, this may be the cause. Ensure that the battery connections are good and the battery is fully charged. If the connections are good and the battery is fully charged, but the voltage still drops below 11 volts, you may need to use a larger battery.

The AEP-700’s cooling fan operates by detecting output power and over temperature conditions of the inverter. Upon starting the inverter, with the output power is under 1/2 capacity (300W), the cooling fan remains off, complying with energy savings specifications. After the output power exceeds 1/2 capacity (300W), the cooling fan will turn on to decrease the internal temperature. If the ventilation opening is obstructed, the inverter will enter over temperature protection mode (OTP). The cooling fan will continue working to drop the inner temperature. When the internal temperature decreases sufficiently, the inverter will turn on automatically. 3. Maintenance: Very little maintenance is required to keep your inverter operating properly. You should clean the exterior of the unit periodically with a dry cloth to prevent accumulation of dust and dirt. At the same time, tighten the Screws on the DC input terminals. 4. Troubleshooting Guide: A common problem with inverter operation is television interference. Operation of the power inverter can interfere with television reception on some channels. In this situation, the following steps may help to alleviate the problem: � Make sure that the chassis ground lug on the back of the power inverter is solidly connected to the ground system of your vehicle, boat or home. � Do not operate high power loads with the power inverter while watching television. � Make sure that the antenna feeding your television provides an adequate (“snow free”) signal and that you are using good quality cable between the antenna and the television. � Move the television as far away from the power inverter as possible. � Keep the cables between the battery and the power inverter as short as possible and twist them together about 2 to 3 twists per foot. This minimizes radiated interference from the cables.

6-1 General Safety Precautions 6-1-1 Do not expose the AEP-700 Inverter to rain, snow, spray, bilge or dust. To reduce risk of hazard, do not cover or obstruct the ventilation openings. Do not install the AEP-700 Inverter in a zero-clearance compartment. Overheating may result. 6-1-2 To avoid the risk of fire and electronic shock, make sure that existing wiring is in good electrical condition and that wire size is not undersized. Do not operate the AEP-700 Inverter with damaged or substandard wiring. 6-2 Precautions When Working with Batteries 6-2-1 If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately flush with running cold water for at least 20minutes and seek medical attention immediately. 6-2-2 NEVER smoke or allow a spark or flame in the vicinity of battery or engine compartment. 6-2-3 Do not drop a metal tool on the battery. The resulting spark or short-circuit on the battery or other electrical part may cause an explosion. 6-2-4 Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery. A lead-acid battery produces a short-circuit current high enough to weld a ring other metal to the skin, causing a severe burn. WARNING! Before installing and using your AEP-700 inverter, be sure to read and save these safety instructions.
