500 Watt DC to AC Power Inverter Conver ts 12 V D C B a t t e r y P o w e r to 110V A C H o m e P o w e r O W NER' S M A NU A L – SAVE THESE INSTRUCTIONS – The recommended source of power is a 12-volt deep-cycle battery due to their high reserve power capacity. Automotive batteries are recommended for only a short period of time of an hour or less.
The advanced surge capacity of the PI-1500 power inverter gives it the means to start most electrical devices including: color televisions, TV/VCR/DVD combinations, small microwaves, refrigeration electric coolers, small air conditioners. Warning: Handling the cord on this product or cords associated with accessories sold with this product, may expose you to lead, a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
• Do not place the inverter in direct sunlight. The ideal air temperature for operation is between 30º and 105ºF. • Keep the inverter well ventilated in order to properly disperse heat generated while it is in use. • While in use, make sure there are several inches of clearance around the top and sides of the inverter. • Do not use the inverter near flammable materials. • Do not place or install the inverter in areas such as battery or engine compartments where fumes or gases may accumulate.
• If you are powering the inverter with an automobile or marine battery, start the engine every 30 to 45 minutes and let it run for about 10 minutes to recharge the battery. • If you hear a continuous alarm or automatic shut down, turn the inverter OFF immediately. Do not restart the inverter until the source of the problem has been identified and corrected. • Disconnect the inverter when not in use in order to avoid battery drain.
In the event of a power overload, the inverter is designed to automatically shut down. This safety feature prevents damaging the inverter while testing devices and equipment within the 1500-watt range. If a device will not operate properly when first connected to the inverter, turn the inverter rocker switch ON (I), OFF (O), and ON (I) again in quick succession. If this procedure is not successful, it is likely that the PI-1500 inverter does not have the required capacity to operate the device in question.
2. Place the back of the PI-1500 with the mounting bracket against a secure and flat surface. 3. Attach the inverter to the flat surface using corrosion resistant screws. Inverter Features: A. ON/OFF Rocker Switch – Turns inverter on and off. B. LED Indicator Light – (Green = power ON, Red = Overload, interruption in power). C. Two, 110V GFCI AC Outlets D. One Pair, 12-Volt Power Cords E. Two, High Speed Cooling Fans – keeps inverter cool. The speed of the fan is faster as the load increases.
Grounding the PI-1500 To avoid electrical shock, it is necessary to ground the PI-1500 Inverter as well as the device powering it. The inverter should be grounded using #8 AWG copper wire (not included). Note: Do not turn on the inverter or the power source until the inverter and the power source are grounded. 1. Turn off the PI-1500. 2. Locate the chassis ground screw underneath the negative terminal on the left side of the inverter. Unscrew the two hex nuts and one washer. 3.
Connecting Inverter Cables The inverter and the power source must be in the OFF mode. Inverter Connection: 1. Locate the positive and negative plastic terminals located on the left side of the inverter. Using a flathead or standard screwdriver, unscrew the positive (red) and negative (black) terminal screws just enough to be able to insert the bare end of the connector cables. 2.
Connecting Your PI-1500 To Turn ON: 1. Push the rocker switch, located on the right side, to the “ON” (I) position. The LED indicator light should glow GREEN verifying the inverter is receiving power and can deliver power to your device. (A brief audio alarm may sound or red LED may flash. This is normal.) 2. Turn on the power source or device to be powered. Note: If more than two devices are to be powered, start one device at a time to avoid a power surge and overloading the inverter.
Using GFCI Outlet The GFCI (Ground Fault Interrupter) must be tested before each use. To test: 1. Turn the inverter ON. 2. Push the "Reset" button located on the GFCI receptacle, first to assure normal GFCI operation. 3. Plug a nightlight (with an "ON/OFF" switch) or other product (such as a lamp) into the GFCI receptacle and turn the product "ON." 4. Push the "Test" button located on the GFCI receptacle. The nightlight or other product should go "OFF." 5. Push the "Reset" button, again.
inverter to reset. To reset: press the “TEST” button (stops flow of electricity to outlet) on the outlet face. Next, press the “RESET” button (restores flow of electricity to outlet) on the outlet face. LEDs and Audio Alarms Green – Power On Red Light and/or Audio Alarm Current Overload – Red LED glows for a short time and inverter shuts down. Current load too high for inverter. Reduce current demand. Voltage Overload – Red LED glows and inverter shuts down. Voltage range of 15.5V ± 0.
power consumption. When the inverter is OFF, no lights appear. 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 115V AC wall outlet).
Blown Fuse A blown fuse is usually caused by reverse polarity or a short circuit within the device or equipment being operated. If the fuse blows, take the inverter to a qualified technician for repair. Power Source Your average automobile or marine battery will provide an ample power supply to the inverter for 30 to 45 minutes even when the engine is off. The actual length of time the inverter will function depends on: 1. Age and condition of the battery. 2.
Safety Features The LED Indicator light will turn from GREEN to RED and the inverter will automatically turn itself off when: 1. The power input from the battery drops to approximately 10 volts. (When the power input drops to approximately 10.5 volts, an alarm will sound for an extended period). 2. The power input from the battery exceeds 15.5 volts. 3. The continuous load demand from the equipment or device being operated exceeds 1500 watts. 4. The case temperature exceeds 140 ºF.
STAGE 2: The inverter then converts the 145-volts DC into 110-volts AC (household voltage) using advanced MOSFET transistors in a full bridge configuration. A "modified sine wave" waveform is generated by this conversion. Troubleshooting PROBLEM: Low or No Output Voltage Reason/Solution 1. Poor contact at terminals. Unhook and rehook the 12-volt connections. 2. Using incorrect type of voltmeter to test output voltage. Use a true RMS reading meter. PROBLEM: Red LED On Reason/Solution 1.
PROBLEM: Audible Alarm On All The Time Reason/Solution 1. Input voltage below 11 volts. Recharge or replace battery to maintain adequate power input. 2. Poor or weak battery condition. Recharge or replace battery. PROBLEM: Device Does Not Work Reason/Solution 1. Device does not turn on. Try turning the inverter ON, then OFF, then ON again. Contact the device manufacture for start up surge and/or if the device is compatible with a modified sine wave.
