User manual SIMA STP-600

[. . . ] Date Purchased ___________ ___________ This package Includes STP-325 Power Inverter Cable with Alligator clips ­ 30" Cable with cigarette lighter adapter Instruction manual (this document) Key Features The STP-325 is designed for high-efficiency operation to provide the most output with the least battery power usage. Advanced protection · Thermal Protection shuts the unit off to guard against the unit getting too hot · Overload Protection protects the unit from excessive loads · Under Voltage Protection turns the unit off to protect the battery from being over discharged This Sima power inverter produces a modified sine wave output which is suitable for most AC loads. CAUTION: There are a few battery chargers that are not compatible with modified sine wave operation. [. . . ] 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-325 will also draw a small current - less than . 25 amps when not operating, so it should be disconnected from your car's battery if your vehicle will not be used for a few days. CAUTION: The power inverter must be mounted securely in any type of moving vehicle. In an emergency situation, if the power inverter is not securely mounted, it could cause bodily injury Lights and Alarms Power Indicator (Green) This 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. Connection to Power Source The STP-325 requires connection to a standard 12 volt DC power source such as the batteries found in most cars, trucks, RVs and boats. The power source must provide between 11 and 15 volts Dc and be able to provide sufficient current to power the load. When the load exceeds 150 watts, use the cables with alligator clips for direct connection to the 12 volt battery. To prevent explosion from the battery gasses, when connecting jumper cables, always connect the wires to the inverter first. Overload Fault Indicator (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 To connect the STP-325 to your 12 volt battery (Figure1): 1. Connect the red (+) wire to the positive (+) terminal on the STP-325 and the black (-) wire to the negative (-) terminal. Connect the red (+) alligator clip to the positive (+) battery terminal and the black (-) alligator clip to the frame or engine of the vehicle. An under-voltage fault (beep) An under voltage fault can occur when the input voltage reaches about 10. 2 volts. The STP-325 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-325 internal circuitry gets too hot due to overload or improper air circulation. The STP-325 will turn off the green power light. Fuse Replacement Cigarette Plug fuse (see figure 3) If you overload the STP-325, it is possible to blow the fuse in the cigarette plug. 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. Always determine why the fuse blew and remedy the problem before using the STP-325 again. Figure 2 Figure 1 Unit fuse (see figure 4) If the fuse blows, disconnect both power leads from the battery. Always determine why the fuse blew and remedy the problem before using the STP-325 again. To connect the STP-325 using the cigarette plug adapter (Fig. 2): The STP-325 also comes with a cigarette lighter plug for easy connection to the power source, Use the cigarette lighter plug, only when powering loads less than 150 watts. [. . . ] 115 VAC Output voltage reads incorrectly. Load is trying to draw too much current. RF interference from power inverter How to calculate power usage. Most products have a power rating on them such as 45 watts. Thus . 9 amps x 115 = 104 watts. Turn on the STP-325 Plug the appliance you want to use into the 115 VAC power outlet on the STP-325 (see the chart below for suitable appliances to use with the STP-325). [. . . ]
