Use proper size wiring. High power inverters can draw many amps from the 12v source and can melt wires if not fused and sized properly.

• Under Voltage Protection turns the unit off to protect the battery from being over discharged The Sima power inverter produces a modified sine wave output which is suitable for most AC loads. This includes lights, appliances, motors, TVs and most electronics.
Overview of the Power Inverter The Sima power inverter is an electronic device that converts the low voltage 12 volt from a battery or other power source to 115 VAC to run standard household appliances. (See the section on How it Works to learn more about the technology used in the Sima power inverter.)
Installation Installation Overview There are three basic steps you need to follow when installing the power inverter. 1) Mounting: Mount the inverter securely 2) Wiring: Wire the inverter to a 12 volt source 3) Testing: Test for proper operation Step #1: Mounting the Inverter The power inverter should be secured to a solid flat surface capable of handling the weight of the unit.
Remember to recheck all connections every few months of operation. SPV-8, SPV-10 and SPV-15 - Strip ½” of insulation off of the wire and insert into the terminal on the inverter. Do not tin the wire. Tighten the set screw securely using a proper size screwdriver.
Remote On/Off Jack The SPV-8, SPV-10, SPV-15 and SPV-25 contain a jack which interfaces with an optional remote on/off switch. Contact Sima for additional information. CAUTION: Do not plug a telephone into this jack as damage or improper operation may occur.

If the inverter does indicate proper voltage, 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. Turn the power switch on the power inverter on so the VOLTAGE meter indicates between 12 and 14 volts.
Operation Equipment Power Usage It is important to use only products that draw less than the power rating of the power inverter. Use of products greater than the rated power rating may either cause the protection circuitry of the power inverter to shut down or the fuse to blow.
the charge in your car’s battery. In addition, the power inverter will also draw a small current, less than 0.1 amp, when turned off and not operating. Therefore, it should be disconnected from your car’s battery if your vehicle will not be used for more than a day. The following chart shows typical operation time for two typical car batteries with the engine not running for various loads.
Under Voltage Mode The amber segments will light and the power inverter will begin to beep if the battery voltage drops below about 10.5 volts. When the voltage reaches about 10 volts, the power inverter will shut off protecting your battery from being completely discharged. Note, it is normal for the unit to emit a short beep when first connected to the power source.
How the Inverter Works The Sima power inverter has two electronic sections. The first section converts 12 volts DC to approximately 160 volts DC using modern high frequency conversion techniques that uses small lightweight efficient transformers. The second section converts the 160 volts DC to 115 VAC using high efficiency power MOSFET transistor devices.
