GENERAL INFORMATION
Important Safety Instructions
To ensure reliable service, your power inverter must be installed and used properly. Please read the installation and
operating instructions thoroughly prior to installation and use. Pay particular attention to the WARNING and CAUTION
statements advice against certain conditions and practices that may result in damage to your inverter. The WARNING
statements identify conditions or practices that may result in personal injury.
Read All Instructions Before Using This Power Inverter!
WARNINGS
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, EXPLOSION OR INJURY
1. Do not connect to AC distribution wiring.
2. Remove appliance plug from outlet strip or turn off inverter before working on the appliance. Multiple outlet
power strips with switches and circuit breakers only interrupt power to the “hot” receptacle terminals. The
“neutral” terminals remain powered with respect to the “ground” terminal.
3. Do not make any electrical connections or disconnections in areas designated as IGNITION
PROTECTED. This includes 12 Volt DC cigarette plug connections, and terminal connections.
4. This is not a toy.
5. DO NOT install object into air vents.
CAUTIONS
1. Do not use with positive ground electrical systems. (All late model tractors or trucks have negative ground
systems) Reverse polarity connections will result in a blown fuse and may cause permanent damage to the
inverter.
2. This inverter will not operate high wattage appliances over the output power limit or surge power limit.
3. Grounding the neutral will cause the inverter to shut down. Do not operate this inverter if it is wet. Do not install
in the engine compartment –please install in a well-ventilated area.
4. This inverter is not tested for use with medical devices.

IMPORTANT CABLE INFORMATION
Substantial power loss and reduced battery operating time results from inverters installed with cables that are not able to
supply full power. Symptoms of low battery power can result from cables that are either excessively long or an insufficient
gage. The installer /operator should be especially aware of the requirements to maintain secure, tight, water-resistant
electrical connections and to provide strain relief for the DC cables and the appliance wiring. Cable insulation must be the
appropriate type for the environment. The inverter harness supplied by Purkeys Fleet Electric was specifically designed
for each tractor model. This harness meets or exceeds all requirements for safe and effective inverter operation.
INTRODUCTION
Your new power inverter is an advance designed DC to AC inverter. With proper care and appropriate usage, it will give
you years of dependable service. This inverter is designed with a universal protection circuit that provides added safety
features, automatic shutdown, earth fault protection and a low battery alarm to prevent damage to your battery system.
This power inverter is configured with the latest low interference technology (L.I.T.), Universal Protection Circuit (UP-
-Circuit) and Soft Start circuit to improve the inverter operation.
UP-Circuit provides full automatic inverter and battery pack protection. This includes overheat protection, battery pack
protection; overload protection, short circuit protection and earth fault protection.
L.I.T. greatly improves the interference problems of common power inverters. You now will enjoy a clean and powerful
AC source.
Soft Start Circuit provides three major features. First, a gradual voltage ramp-up during inverter start--up. This
eliminates failed cold starts under load. Second, output that momentarily dips in the voltage and quickly recovers. This
eliminates most shutdowns from momentary overloads. Last, the inverter automatically re-starts when an overload that
caused the inverter to shutdown is removed.
PROTECTIVE FEATURES OF THE INVERTER
OVER TEMPERATURE PROTECTION –If the temperature inside the inverter is too high, the unit will automatically
shut down. Allow the unit to cool for at least 15 minutes before restarting after a heat –related shutdown. Unplug
unit while cooling.

LOW BATTERY VOLTAGE PROTECTION –This condition is not harmful to the inverter but could shorten battery life.
The inverter automatically shuts down when the input voltage drops to 11.5 volts.
OVER VOLTAGE PROTECTION –The inverter will automatically shut down when the input voltage exceeds 15.5 volts DC.
Input voltage exceeding 16 volts could damage the inverter.
OVERLOAD PROTECTION –The inverter will automatically shut down when the continuous draw exceeds rated watts.
SHORT CIRCUIT PROTECTION –This inverter will shut down. Remove the short circuit and restart the inverter.
EARTH FAULT PROTECTION –This inverter complies with the standard current leakage allowance. When large current
leakage to earth terminal occurs, the protection circuit will activate and shut down the inverter, which prevents electric
shock. To restart the inverter, turn it off. Then unplug the fault AC appliance and turn the inverter back on.
LOW BATTERY ALARM –An alarm will sound when the voltage from the battery pack drops to 11.0 volts. This is an
indication that the battery pack needs to be recharged or there is excessive voltage drop in the input cables. NOTE: It is
normal for the alarm to sound while the unit is being connected to or disconnected from the power source. This is not
indicative of problems.
WAVE FORM –This inverter is a Modified/Quasi wave sine. Some devices like medical equipment may require a PURE
SINE WAVE inverter. Please check with us to verify.

OPERATING ENVIRONMENT
For best operating results, the inverter should be placed on a flat surface such as a floor, wall or other solid surface. The
inverter should only be used in locations that meet the following criteria:
DRY-Do not allow water and/or other liquids to come in contact with the power inverter.
Cool-Ambient air temperature should be between 30 degrees F and 105 degree F. Do not place the inverter on or near
a heating vent or any piece of equipment that is generating heat above room temperature. Keep the power inverter
away from direct sunlight if possible.
Ventilated- Keep the area surrounding the power inverter clear to ensure free air circulation around the unit. Do not
place items on or over the power inverter during operation.
Safe- Do not use the power inverter near flammable materials or in any locations that may accumulate flammable fumes
or gasses.
Mounting- The power inverter can be operated in any position, however if mounted on a wall, mount it horizontally so
the indicators, switch, outlets and terminals blocks located on the front panel are visible and accessible.

CHASSIS GROUND OR FAULT GROUND CABLE- The chassis ground lug is used to connect the chassis of the inverter to
the DC grounding point as required by regulations. Installing the grounding cable is a protective measure used to provide a
path for fault currents. The inverter has 12 volt positive and negative connected to the electronics inside the inverter. If the
positive cable somehow came in contact with the chassis of the inverter, the ground cable would conduct the fault currents
long enough to cause the over current protection (fuse or breaker) to interrupt the circuit between the inverter and the
battery. (Should be Zero volts)
R-TERMINAL OR REMOTE SENSE STUD- The R-Terminal or Remote Sense stud is used to be able to tell the inverter if
the engine is running or off. (Should be 7 to 14 volts when the engine is running and zero volts when the engine is off.)
