STP-120 Power Inverter STP-120 Power Inverter Warnings & Cautions To reduce the risk of fire, electric shock, explosion or injury: • • • • • • Do not connect to AC distribution wiring. Remove appliance plug from outlet strip or turn off inverter before working on the appliance. Power strips with switches and circuit breakers only interrupt power to the “hot” receptacle terminals. The “neutral” terminals remain powered with respect to the ground terminals. Not approved for ignition protected areas.
STP-120 Power Inverter Troubleshooting Common power problems Possible causes Recommendations Battery voltage Recharge battery or check DC below 9.5 – 10.5 power supply volts Equipment being Reduce load to maximum of operated draws too 120 watts much power Inverter in thermal Allow the inverter to cool. Be shutdown condition sure there is adequate ventilation around the unit.
STP-120 • • • • • • • • Power Inverter This inverter will not operate high wattage appliances that produce heat such as hair dryers, microwave ovens and toasters. Do not use with a positive ground electrical system. Reverse polarity connection will result in a blown fuse and may cause permanent damage to the inverter. The majority of cars, trucks, RVs and boats in the U.S. are negative ground. This inverter is not tested for use with medical devices. Do not open the inverter.
STP-120 Power Inverter Protective Features The inverter monitors these conditions: Low Battery Voltage – This condition is harmful to the inverter, but could damage the power source, so the inverter will automatically shut down when the input voltage drops below 9.5 – 10.5 volts DC. Input Voltage Too High – The inverter will automatically shut down when the DC input exceed 15 volts. Thermal Shutdown – The inverter will automatically shut down when the unit becomes over heated.
