INTRODUCTION Power on Board Power Inverters are geared for maintaining today's modern life while traveling in Vans, RVs, automobiles, trucks, or vehicle that has 12 volt battery power supply and a means to recharge those batteries. This Maxx 1500 Inverter is supplied with: 1. On/Off switch 2. Triple Outlet 3. Dual LED indicators that indicate operation (POWER), shutdown (FAULT). 4. Cooling fan 5. A grounding terminal for electrical safety. 6. DC cable connectors 7. Internal protective circuits that include: • Automatic overload and over-temperature shutdown (activated if AC output exceeds maximum power) • Automatic AC short-circuit shutdown . RED FAULT LED lit. • Automatic low voltage audible alarm. • Automatic low-voltage shutdown. • Automatic high-input voltage shutdown. Maxx1500 Series - is a state-of-the art, highly efficient DC to AC power inverter that changes 12 volts DC from a battery to 120 volts AC, 60 Hz. With proper DC power, it can continuously deliver up to 1500 watts AC. All Power on Board inverters have two methods of preventing batteries from being completely discharged. When your batteries begin to drop in voltage, the inverter will sound an alarm. You can either turn off the inverter or leave it unattended. Further discharge will automatically turn off the inverter. If your battery does go to complete discharge, it's because some other appliances are drawing power from the battery.

TOUR OF MAXX 1500 - SERIES INVERTER AC power is supplied via three North American, household-type receptacles as shown in FIGURE 1. This allows the connection and operation of most 120 VAC- powered electrical and electronic appliances that use a standard plug. The rest of the front panel items are: One FAULT LED. When this lights, the inverter is shut down. One POWER LED that lights when the inverter is operating. One ON/OFF switch that shuts off all inverter functions. The ON/OFF switch can also be used to reset the inverter after the inverter shutsdown due to a fault condition such as overload, over temperature, short circuit or high voltage.

THEORY OF OPERATION The inverter changes 12 VDC into 120 VAC (120 VAC RMS), electrical power. This is accomplished in two stages. The first stage raises the 12 VDC input to 145 VDC through modern high-frequency conversion techniques. The output stage changes the 145-VDC to 120 VAC. The inverter's output stage uses multiple banks of metal- oxide semiconductor field-effect transistors (MOSFETs) to alternately apply opposite polarity to the AC outlet's HOT and NEUTRAL terminals. The AC output approximates a sine wave in shape. This is called Modified Sine Wave (MSW) and it has the same energy characteristics as the sine wave of commercial electrical power.

DO Not use inverters with the above types of equipment. The majority of portable appliances do not have this problem. Most portable appliances use separate transformers or chargers that plug into AC receptacles to supply a low-voltage DC or AC output to the appliance. If the appliance label states that the charger or adapter produces a low-voltage DC or AC output (30 volts or less), there should be no problem powering that charger or adapter. Check operating temperature of small motors. If the motor operates at much higher than normal temperature there may be an incompatibility problem. Discontinue use and compare temperatures while operating the appliance from commercial AC power.

DC CONNECTION PRECAUTIONS IMPORTANT CABLE INFORMATION Use cable information in Appendix A for determining gauge of cable. Use DC Inverter terminal connections on cable ends. The user must maintain secure, tight, electrical connections. Use correct gauge DC cabling to supply up to 150 amps, or maximum load. Keep cabling short to avoid voltage drop and reduced operating time. Inverters are supplied with a grounding terminal. Connect an insulated AWG 12 wire to this terminal and connect the other end to a solid electrical ground. This is an important safety wire that ensures proper grounding. DO NOT CONNECT THIS WIRE DIRECTLY TO THE NEGATIVE DC INPUT TERMINAL OF THE INVERTER, or Battery. At full 1500 watt load, the DC input requirements are up to 150 amperes at 12 volts DC. For most continuous-duty applications, multiple battery configuration and the use of deep-cycle batteries is a requirement. With vehicles using multiple batteries, inverters should be operated from one of the vehicles 12 volt batteries, so there's always one battery with adequate charge to start an engine.
DETERMINING BATTERY CAPACITY FOR EXTENDED RUN TIMES. I nverters must be supplied with a constant source of high current 12 volt DC from a battery or bank of batteries. To determine the minimum battery size that you will need to operate appliances from the inverter without a generator or alternator charging the battery, follow these steps: 1. Determine the wattage of each appliance and/or tool you will need to simultaneously ...
WARNINGS CONTINUED: DANGER OF EXPLOSION. BATTERY CHARGING, DISCHARGING AND ENGINE OPERATION PRODUCE EXPLOSIVE GASSES. MAKE SURE THE AREA AROUND THE BATTERY IS WELL VENTILATED AND NO BATTERY CHARGING IS OCCURRING. WEAR PROTECTIVE EYEWEAR WHILE CONNECTING TO NON-SEALED LEAD ACID BATTERY. Place the inverter as close to the battery supply a practical making sure the inverter is secure, dry, and cool. Make sure the length and gauge of cable are correct for the installation. (See Appendix A) ...

11. Make the connections to the FUSE HOLDER and battery terminal 12. Do not install fuse yet. 13. Connect the Negative cable ring terminal to the battery NEG terminal. 14. Insert the fuse into the fuse holder. There may be momentary sparking. 15. Check all connections and tighten any loose connections. 16. Turn ON the inverter and apply a test load to the AC outlets. Any questions please contact Power on Board Technical Support at: (954) 584-4446 EXT. 119 for professional direction. SERVICE AND REPLACEMENT PARTS FUSES It is recommended but not required since there is internal fuse protection that the user use an external inline ANL 300 fuse and fuse holder(not supplied). The fuse holder, and the ANL-300 fuse (not supplied) can be purchased at most electrical supply companies.It is also recommended that an Automotive Electrician be used to install this cable.

TROUBLESHOOTING - COMMON PROBLEMS POWER TOOLS AND MICROWAVE OVENS WON'T START: Read the information panel on each power tool carefully to accurately determine the tool's input wattage. The wattage output is sufficient to operate most power tools and microwave ovens but remember that the power needed to start the power tool may be as much as 2 to 6 times its continuous wattage requirements. "BUZZING" SOUND IN AUDIO SYSTEMS AND/OR SNOW IN TVS: Inverters are shielded to minimize interference with TV signals. Ensure that the TV antenna provides an adequate "snow free" signal and that the antenna cable is high quality and shielded without the inverter operating. The problem may not be with the inverter. However, in some cases, some interference may be visible, particularly with weak TV signals. Try the following corrective measures: • Position the TV and antenna further away from the inverter if it is the cause of interference. Adjust the antenna, or use shielded cable hookup (if possible) to an external antenna. • Do not operate high-power appliances or tools when you are watching TV.
