1 INTRODUCTION
Thank you for purchasing a Vanner 300 Watt VLT SERIES Inverter. We are confident that you will be
satisfied with the inverter’s performance and its many features. With proper installation and care, you can
look forward to years of service from this high performance product.
This document will describe the operation, technical specifications and installation procedures.
2 IMPORTANT SAFETY INSTRUCTIONS
Electrocution hazard exists
Fire hazard exists
A potentially dangerous condition
Explosive hazard exists
Corrosive hazard exists
To get the most out of the power inverter, it must be installed and used properly. Please read the
instructions in this manual before installation. Keep this manual for future reference.
General Safety Precautions
Do not expose the inverter to rain, snow, spray, or dust. To reduce risk of hazard, do not obstruct
the ventilation openings. Do not install the inverter in a zero-clearance compartment. Overheating may
result.
To avoid a risk of fire and electric shock, make sure the wiring is in good electrical condition
and is proper gauge. Do not operate the inverter with damaged or substandard wiring.
This equipment contains components that can produce arc or sparks. To prevent fire or
explosion, do not install in compartments containing batteries or flammable materials or in locations which
require ignition protected equipment This includes any space containing gasoline-powered machinery,
fuel tanks, or joints, fittings, or other connection between components of the fuel system

Precautions When Working With Batteries
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters
eye, immediately flood eye with running cold water for at least 20 minutes and get medical attention
immediately.
Never smoke or allow a spark or flame in vicinity of battery or Engine.
Do not drop a metal tool onto the battery. The resulting spark or short-circuit on the battery or
other electrical part may cause an explosion.
Remove personal metal items such as rings, necklaces, and watches when working with a lead-
acid battery. A lead-acid battery can produces a short-circuit current high enough to weld a ring or the like
to metal, causing severe burns.

3.2 Front Panel
ON / OFF Control Switch
The ON/OFF Switch must be in the ON position when using Remote Control.
Remote Control Terminal
A green two-terminal connector located on the front panel allows remote ON/OFF control of the inverter
by a customer-supplied ON/OFF switch.
Standard Operation (Not using remote control): The inverter is shipped with a jumper connecting
terminals Vout and Vin. With the jumper in place (remote control not being used) the inverter is fully
functional using the ON/OFF Control Switch located on the front of the inverter.
Remote Control via customer-supplied SPST switch: If it is desired to remotely control the inverter from a
customer-supplied remote switch, remove the jumper connecting terminals Vout and Vin. Supply a 12v
(24v signal on 24v units) continuous signal to terminal Vin to turn the inverter ON. The source of the 12v
signal can be battery voltage for single-wire remote control or terminal Vout for two-wire-remote-control.
The most common remote control wiring arrangement uses a "hot in run" circuit from the vehicle fuse
panel for the 12v signal. This arrangement automatically turns the inverter ON when the vehicle is ON
and automatically turns the inverter OFF when the vehicle is OFF.
Green Connector Details: Terminal Vout is current limited, therefore if terminal Vout is used as the source
for the remote control signal, a fuse is not required in the remote control circuit. If Vout is not used as the
remote control signal, use a 5 amp fused circuit for the remote control signal.
The green connector can be removed from the inverter by pulling the connector outward. The two
upward facing screws are used to tighten the compression terminals for attachment of the signal wire(s).

AC Output GFCI Duplex Receptacle
The AC output neutral conductor is connected to AC ground and inverter chassis ground inside
the inverter. This conforms to National Electrical Code requirements that separately derived AC
sources (such as inverter and generators) have their neutral conductors tied to ground in the
same way that the neutral conductor from the utility is tied to ground at the AC breaker panel.
Do not connect AC neutral to AC ground downstream of the GFCI. This would cause the GFCI to
trip.
Never connect the inverter output to another AC power source such as a generator or utility power.
The inverter would be destroyed.

4 INSTALLATION
4.1 Inverter Installation Considerations
Mounting: Locate a flat secure, dry, horizontal or vertical surface large enough to mount the inverter.
The location should be as close to the battery as practical, usually within six feet, but not in the same
compartment and should provide adequate ventilation while the inverter is operating. The location
must be clean, dry and free from road spray, dripping water or other moisture contamination.
Cooling Fan Clearance: The mounting location must allow unobstructed airflow for cooling. Allow a
minimum clearance of 3 inches on the front and back of the inverter. The Cooling Fan is
thermostatically controlled. Obstruction of the fan exhaust or the front intake vents will diminish the
inverter output capacity due to overheating.
4.2 DC Wiring Considerations
Do not connect the 12V model to a 24V battery. The unit will be destroyed immediately.
Operation of the inverter without a proper ground connection may result an electrical safety hazard.
Damage caused by reversed polarity will void warranty.
A DC FUSE IS REQUIRED to protect the DC cables in case of a short circuit. The wiring of
the inverter installation should conform to the National Electric Code (NEC) and any other state or
local codes in effect at the time of installation. Article 551 of the NEC requires any DC cable from a
battery, which measures longer than 18 inches along its length, be protected by a fuse.
BE AWARE, as a large number of capacitors become charged upon completion of the DC
circuit, THERE WILL BE A LARGE SPARK when the last battery connection is made. The spark is
normal and will occur every time the batteries are connected. It is advisable to make the last DC
connection at the inverter, not at the battery, to reduce the risk of battery explosion.
To minimize electromagnetic radiation that could interfere with sensitive electronics, route the AC
output wiring and DC power wiring with as much physical separation as possible from low voltage
wiring such as audio and video signal wires. Route the DC positive and negative cables as close
together as possible and use cable ties to keep them together.
If passing through steel or other ferrous metal walls, the DC input cables need to pass through the
same hole to prevent causing a transformer effect. If two holes are required, cut a slot to connect the
two holes to prevent heating of the ferrous metal.
Proper DC cable size is critical for the performance and safe operation of the inverter
system. The DC Cable and Fuse Sizing Chart shows the minimum cable sizes recommended. These
sizes allow a ½ volt maximum voltage drop at maximum inverter capacity and will insure optimum
inverter performance. DC cable to be used with these fuse sizes should be minimum insulation
temperature rating of 105°C and voltage rating of 600V.
DC cables should be as short as possible.
Do not use the vehicle chassis as the DC negative conductor. The negative cable should be the same
size as the DC positive cable and should be connected directly to the battery negative terminal.

4.3 DC Wiring Installation Procedure
Verify the Power ON/OFF Switch is in the OFF position before connecting inverter to the battery.
Route the negative DC cable to the battery. Verify cable polarity before proceeding. The fuse will be
blown and inverter may be damaged if the DC cables are reversed. Route the positive DC cable to
the fuse and then to the battery. Protect cables with loom and use grommets or other appropriate
means where cables may contact hard, sharp edges.
Connect Chassis Ground Bonding Lug to the vehicle chassis and/or earth ground using 12AWG or
larger copper wire. (The wire must be sized to safely carry DC current as needed to blow the DC fuse
located near the battery in the inverter’s positive DC input cable.)
