This occurs because the power supply in the electronic device does not adequately filter the modified sine wave produced by the inverter. The only solution to this problem is to use a higher quality sound system that incorporates a higher quality power amplified supply. Television Interference The Inverter is shielded to minimize interference with TV signals. However, in some instances, some interference may still be visible, particularly with weak TV signals. Try the following corrective measures: • Position the inverter as far as possible from the television, the antenna and the antenna cables. Use an extension cable, if necessary. • Adjust the orientation of the inverter, the antenna cables and the TV power cord to minimize interference. • Make sure the antenna feeding the television provides an adequate (“snow free”) signal and that high quality, shielded antenna cable is used. • Do not use the inverter to operate high-power appliances or tools at the same time you are using it to operate the TV. • Make sure the inverter’s case is properly grounded (refer to the “Permanent Installation Procedure” section of this Instruction Manual). Fault Protection and Troubleshooting Guide INVERTER POWER SWITCH TURNED ON Trouble/Indication Possible Cause Suggested Remedy No AC output — red LED lit DC input is below 10 volts Recharge or replace battery. Excessive appliance load — thermal shutdown Turn unit OFF. Reduce the load, wait for the inverter to cool down, then turn the unit ON again. No AC output — green LED not lit Fuse(s) open Check DC input — fuse(s) in vehicle. Replace the fuse with one of the same type and rating if necessary. Low battery alarm sounds continuously Low battery voltage Recharge battery. Remove load from the inverter while recharging battery. Bad connection or wiring Tighten all DC connections. Motorized power tool will not start Excessive start-up load If appliance does not start, appliance is drawing excessive voltage and will not work with inverter. Motorized power tool does not operate at correct speed Purely inductive load Make the load not purely inductive. Operate an incandescent lamp at the same time as motor. Television/radio interference Snow in picture, “buzzing” sound Keep inverter and antenna distant from each other. Use shielded antenna. Connect antenna to amplifier. Resetting the Unit When a thermal shutdown problem occurs, WARNING: To reduce the risk of injury or property damage: If the appliance momentarily, turn off the appliance and disconnect 11 90550750 VEC049DCB GOOD ONE.qxp 6/5/09 1:46 PM Page 12 CARE AND MAINTENANCE Storage 1. Ideal storage temperature range is 50-68°F (10-20°C). 2. Store and use the inverter in a cool, dry place with adequate ventilation. 3. Avoid locations that are exposed to heating units, radiators, direct sunlight or excessive humidity or dampness. Fuse Replacement This inverter is equipped with multiple internal fuses. Normally, these fuses will not “blow” unless there is a serious problem inside the unit. Internal fuses are replaceable; however, only trained personnel should attempt fuse replacement. Refer to the “Service Information” section of this Instruction Manual. Preventive Maintenance Inverters require minimal maintenance. For optimum performance, the manufacturer recomments periodically performing the following preventive maintenance. 1. Turn OFF the inverter using the front panel ON/OFF Power Switch. 2. Remove the DC power fuse. 3. Check and tighten all electrical connections, including the ground. 4. Using a non-metallic vacuum cleaner hose, vacuum the air slots and fan area. 5. Clean the outside of the unit using a damp (not wet) cloth. 6. Wipe unit surfaces thoroughly with a dry cloth. 7. Re-insert the fuse and resume operation.
