Power tool operates at incorrect speed
Possible Cause:
- Caused by the purely inductive load
Solution:
- Operate a small lamp or a similar
Note about Modified Sine Wave Inverters
A modified sine wave inverter has a waveform more like a square wave, but with an extra step or so. A modified sine wave inverter will work fine with most equipment, although the efficiency or power will be reduced with some.
Motors, such as refrigerator motor, pumps, fans etc will use more power from the inverter due to the fact that a modified sine wave has a lower efficiency than that of pure sine wave. Most motors will use about 20% more power.
Some fluorescent lights may not operate quite as bright, or may buzz.
Electronic timers and/or digital clocks will often not operate correctly. Many appliances get their timing from the line power, and because the timing of a modified sine wave signal may be slightly different than that of a pure sine wave, clocks and timers may run faster or not work at all.
Note: Some stereo systems and radios may emit a buzzing sound from their speakers when operated from the inverter. This buzzing occurs because the radio or electronic device does not filter the modified sine wave produced by the inverter adequately.
Television interference may occur with some TV signals, even though this inverter is designed to minimize such interference. If a disturbance occurs in a weak TV signal, you may try the following to correct the problem:
-Place the TruePower inverter far away as possible from the television, the antenna cables and the antenna as well. Use an extension cable from the inverter to the TV if necessary.
-Make sure the TV antenna provides a snow free signal when operated on a source other than the inverter. Additionally, we recommend the use of a high quality, shielded antenna cable.
-Coil the TV power cord as well as the input power cables running from the battery to the inverter.
-Attach an AC interference filter or similar filter product between the inverter and televisions power cord. This type of filter is available at most electronic supply stores.
-Try a different Television set as different models and manufacturers vary in their vulnerability to interference.

Personal Safety Precautions Continued
5.Be extra cautious to reduce the risk of dropping a metal tool onto a battery. It may spark or
6.Remove all personal metal items such as rings, bracelets, necklaces, watches and jewelry when working near a battery. A battery can produce a short circuit high enough to weld a ring or any metal, causing serious burns.
7.Never charge or invert power from a frozen battery.
*WARNING: Restrictions on Use- The TruePower inverter shall not be used in connection with life support systems or other medical equipment devices.
Preparing for Installation
Read this entire installation section if you plan a hardwire installation from beginning to end.
WARNING: This devise is not Ignition Protected
Avoid serious injury or death from or explosion. Do not install in compartments containing gasoline fueled engines or gasoline tank, or in areas where ignition protected equipment is required.
WARNING: Do not mount the inverter above or below your batteries.
WARNING: Electrical shock and fire hazards
On Board Solutions, a ProMariner Company recommends all wiring be done by qualified personnel. Disconnect all AC and DC power sources to prevent accidental shock. Disable and secure all AC and DC disconnect devices and automatic generator starting devices. It is the installer’s responsibility to ensure compliance with all the applicable installation codes and regulations.
WARNING: Installation Precaution
The TruePower inverter should be mounted on a flat horizontal surface or a vertical surface with the front panel and label facing the user. In no case should the front or rear endcaps be facing in an upward or downward position. This allows proper ventilation and product safety of the unit as intended by design.
WARNING: Fire Hazard
Do not cover or obstruct the ventilation openings. Do not install this equipment in a compartment with limited airflow; Overheating may result.
