User manual SIMA STP-150

[. . . ] Ambient air temperature should be between 40o and 80o F. Keep out of direct sunlight and away from heating vents. Keep the unit away from flammable material or in any location which may accumulate flammable fumes or gases, such as the battery compartment of your car, boat, RV or truck. · · · Sima Products Corporation 140 Pennsylvania Avenue Bldg. #5 Oakmont, PA 15139 412-828-3700 http/www. simacorp. com · · · P/N 21683 03. 5 Health Advisory Sima Products does not authorize the use of the STP-150 with any products to be used in life support devices or systems. Model No. [. . . ] Do not use a 12V extension cord with this unit. Testing the Power Inverter Make sure the 12 volt power source is wired properly to the power inverter. With nothing plugged into the 115 VAC outlets, turn on the power switch of the STP-150. If the green power light does not come on, turn the power switch off and check your wiring and external fuse. With the inverter turned off, plug the appliance you want to use into the 115 VAC power outlet on the unit. The appliance should now be operational. Important: The STP-150 can draw up to 15 amps from your car's battery when operating. If you are using it for extended periods of time, you will want to operate your car occasionally to maintain the charge in your car's battery. The STP-150 will also draw a small current when not operating, so it should be disconnected from your car's battery if your vehicle will not be used for a few days. Lights and Alarms Power Indicator (Green light) The green light is illuminated when the inverter is turned on and is operating normally. If this light goes out, either the 12 volt power supply is missing (possible blown fuse) or some fault condition has occurred. These fault conditions include: output overload, output short circuit, low input voltage and over-temperature of the unit. This can happen if a device has a large start-up surge, if an appliance (like a drill or saw) is stalled or if the inverter does not have a circulating supply of cool air. Overload Fault (Red light) The red light is illuminated when a current overload fault is detected. An overload fault occurs when the power draw exceeds the inverter's maximum capability. An under-voltage fault (beep) An under-voltage fault can occur when the input voltage reaches about 10. 2 volts. The STP-150 will sound a continuous alarm and shut off when the input voltage drops to 9. 6v to protect your battery from being completely discharged. An over-temperature fault An over-temperature fault occurs when the STP-150 internal circuitry gets too hot due to overload or improper air circulation. The STP-150 will turn off the green power light and the unit will turn off. Fuse Replacement (see figure 2) If you overload the STP-150, it is possible that the fuse in the cigarette plug might blow. If this happens, unplug the cigarette plug from the power source, wait for the tip to cool and unscrew the metal tip on the plug. Remove the fuse and install a new fuse rated at 15 amps. Replace the tip and screw firmly but do not over tighten. Always determine why the fuse blew and remedy the problem before using the STP-150 again. Operation Equipment Power Usage It is important to use only products that draw less than 150 watts with the STP-150. Use of products greater than 150 watts may either cause the protection circuitry of the STP-150 to shut down or the fuse to blow. Repeated use of excessive power draw can cause failure of the STP-150. Most products have a power rating on them such as 45 watts. [. . . ] 1 * Note : Some products, such as televisions, draw a high surge current to start up. If the appliance does not operate and the inverter turns off, you may need a larger inverter. Check that the battery and the 12V wiring to the inverter is large enough to handle the current draw. You may need to turn the power switch on and off a few times to get the appliance "started".
