Purkeys’ Invert™ Pure Sine Wave inverters provide reliable
12 VDC to 110 VAC power in heavy-duty vehicles. ey are available in 1500
and 2000 watts.
GENERAL INFORMATION
DynaBalance™ Monitoring Technology
e Invert comes with a controller that measures input voltage and input
current (even under load) to dynamically estimate the battery’s state of
charge. is enables the controller to indicate available battery capacity and
turn o when the battery’s state of charge drops to turn-o point.
Inverters that do not have this functionality can turn o too late if the inverter
is only supplying a small amount of power, or too soon when the inverter is
supplying high power (such as when powering a microwave).

GENERAL SAFETY
Explosion Hazard:
Do not use the inverter near ammable fumes or gases. Do not use the
inverter in an enclosure containing automotive-type, lead-acid batteries, as
these batteries, unlike sealed batteries, vent explosive hydrogen gas, which can
be ignited by sparks from electrical connections.
Crash Hazard:
Drivers should not congure or troubleshoot the inverter while they are
driving the vehicle.
Shock Hazard:
Keep children away from the inverter; it generates the same potentially deadly
AC power as a normal household wall outlet.
Heated Surfaces:
e inverter housing may become uncomfortably warm, reaching 140˚ F (60˚
C) aer extended operation. Ensure that there are at least 2 inches (5 cm) of
space around the inverter. During operation, keep it away from ammable
materials.
Additional Safety Guidelines:
• Do not insert foreign objects into the inverter outlets or ventilation
openings.
• Never connect the inverter to power utility AC distribution wiring.
• Do not use the inverter in temperatures over 100˚ F (40˚ C)
• Do not expose the inverter to water, rain, snow, or spray.
• Do not use a 24 volt jumpstarter with the inverter connected to the
batteries.
is guide contains important information regarding safety and operation
of this product. Before use, read and understand all cautions, warnings, and
instructions. Failure to do so could result in injury and/or property damage. It
may also void your product warranty.

• Ensure the inverter negative DC input terminal or the battery negative
terminal is connected to earth ground if the inverter is used outside your
vehicle.
• Do not install in the engine compartment—install in a well-ventilated
area.
• Do not use with positive grounded electrical systems (the majority of
modern vehicles use negative grounded electrical systems).
• Observe correct polarity when connecting the inverter DC input
terminals to the battery. Connect the battery positive to the positive
input connector of the inverter and the battery negative to the inverter
negative input terminal. A reverse polarity connection will result in a
blown fuse and may cause permanent damage to the inverter. Damage
due to reverse polarity is not covered under warranty.
• Do not use the inverter if it is wet.
• Do not connect in parallel with another AC source.
• Disconnect appliance plug from inverter AC outlet before working on
the appliance.
• e metal chassis of the inverter and the ground terminal of the outlet(s)
are internally connected to the negative battery terminal on the inverter.
is means the metal chassis of the inverter and the AC load will
automatically be grounded.
• is inverter will not run high wattage applications that exceed the
output power limit or the surge power limit.
GENERAL CAUTIONS
To reduce the risk of re, electric shock, explosion or injury:

Precautions when working with batteries:
• Batteries contain very corrosive diluted sulphuric acid (electrolyte).
Precautions should be taken to prevent contact with skin, eyes, or
clothing.
• Batteries generate hydrogen and oxygen during charging, resulting in an
explosive gas mixture. Be sure to ventilate the battery area and follow the
battery manufacturer’s recommendations.
• Never smoke or allow ame near batteries.
• Be careful not to drop metal tools on the battery, as this could spark
or short circuit the battery or other electrical parts and could cause an
explosion.
• Remove metal items such as rings, bracelets, and watches when working
with batteries. Use caution when working with metal tools, as batteries
can produce a short circuit current high enough to melt/weld metals,
which can cause severe burn.
• If you need to remove a battery, always remove the ground terminal
from the battery rst.
• Do not insert objects into the air vents.

DRAFT
*On the 2000 watt inverter, each AC outlet has a 15 amp circuit breaker/on-o switch.
If the circuit breaker trips, reset the circuit breaker/switch by turning the switch
o, then back on. e switches can also be used to individually switch the three AC
outlets on or o.

INSTALLATION
Step 1: Select the best location and install the inverter in the cab or sleeper of
the tractor.
Step 2: Install the quick release clip
in a convenient location (i.e. the
interior wall of the tractor). It
can be installed in either of the
following ways:
• Use the provided velcro and
stick the clip to the selected
location.
• Use the provided athead
screws to mount the clip.
Step 3: Connect the cable to the REMOTE connection on the inverter, then to
the connection on the base of the controller.
*
* is ground stud is already connected internally to the battery ground stud, the
inverter housing, and the ground of the AC sockets; therefore, it does not need to
be connected in vehicle applications.

Installation Complete
Note: e inverter controller cable can be CAT5, CAT5e, or CAT6 and must
have male RJ45 connectors on both ends (shielded or unshielded are both
okay). e cable must be 8 position and 8 conductor (8p8c) and it cannot
be a cross-over cable. Most RJ45/Ethernet type cables will work as long as
the conductors are 24 gauge or larger.
We recommend :
• the conductors in the cable be 24 gauge or larger
• the cable be 16’ or shorter
HARNESS GAUGE RECOMMENDATIONS
1500 watt inverter: 150 amps with a
maximum voltage drop of 0.5 volts.
2000 watt inverter: 200 amps with a
maximum voltage drop of 0.5 volts.
e following tables show the maximum harness cable length
recommendations for both the 1500 and 2000 watt inverters.
