Safety Information
IMPORTANT
Read all the Cautions and Warnings before installing and using the power inverter. The inverter must
be properly installed. If you are not familiar with 12 volt high current wiring, it is recommended that you
have a professional automotive installer install the inverter.
WARNING
To prevent fire or shock hazard, do not
expose the unit to rain or moisture
This symbol is intended to
alert the user to the presence
of uninsulated “dangerous
voltage” within the product’s
enclosure that may be of
sufficient magnitude to
constitute a risk of electric
shock to persons.
This symbol is intended to
alert the user to the presence
of important operating and
maintenance (servicing)
instructions in the literature
accompanying the appliance.
CAUTION
The power inverter generates 115 VAC power from your 12 volt car battery. Treat the 115 VAC
output just like you treat the 115 VAC in your house. It is just as dangerous.
Do not connect the unit to AC distribution wiring, such as your house wiring.
Keep the unit away from water. Do not allow water to drip or splash onto the power inverter.
Keep the unit in cool environments. Ambient air temperature should be between 32° and 75° 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.
With heavy use, the unit will become warm and possibly hot. So, keep it away from any heat sensitive
materials.
Make sure the opening to the fan and vent holes are not blocked.
Do not open the unit. High voltages are inside.
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.

Introduction
Congratulations on your purchase of a Sima power inverter. It provides 115 VAC anywhere you have
12 volts DC in your car, truck, RV or boat. It is designed to be easy to use and to provide years of
dependable service.
Key Features
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
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.
CAUTION: There are a few battery chargers that are not compatible with modified
sine wave operation. These are typically small rechargeable, battery operated
devices like razors and flashlights that can be plugged directly into an AC
receptacle to recharge. Some chargers for battery packs used in power tools also
should not be used with an inverter. These chargers typically have a warning
label indicating that dangerous voltages are present at the battery terminals.
Only a true sine wave inverter should be used with these types of appliances.
Damage to the device could result if you attempt to use them with any type of
modified sine wave inverter.
Do not use the Sima power inverter with the above devices.
Package Includes

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. It is very important that the unit be secured using the proper sized mounting hardware (not
included) to keep the unit from moving around or becoming loose in emergency situations.
The power inverter should be placed with space around the unit for proper ventilation. Do not block
the air entrance to the fan or block the exhaust holes located on the side or bottom of the unit.
The unit must be mounted in a dry, cool area. Do not allow water to drip or splash onto the inverter.
The ambient air temperature should be between 32° F and 75° F.
The unit must not be mounted in an area with batteries or in any area capable of storing flammable
liquids such as gasoline.
To minimize cable lengths, the unit should be mounted as close as possible to the battery, but not in
the same compartment. If you have a choice, it is better to run longer AC wires than DC cables.
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
