1 Introduction
Thank you for urchasing a Vanner 300 Watt VLT SERIES Inverter. We are confident that you will be
satisfied with the inverter’s erformance and its many features. With ro er installation and care, you can
look forward to years of service from this high erformance roduct.
This document will describe the o eration, technical s ecifications and installation rocedures.
2 Important Safety Instructions
Electrocution hazard exists
Fire hazard exists
A otentially dangerous condition
Ex losive hazard exists
Corrosive hazard exists
To get the most out of the power inverter, it must be installed and used ro erly. Please read the
instructions in this manual before installation. Kee this manual for future reference.
2.1.1 General Safety Precautions
Do not ex ose the inverter to rain, snow, s ray, or dust. To reduce risk of hazard, do not obstruct
the ventilation o enings. Do not install the inverter in a zero-clearance com artment. Overheating may
result.
To avoid a risk of fire and electric shock, make sure the wiring is in good electrical condition
and is ro er gauge. Do not o erate the inverter with damaged or substandard wiring.
This equi ment contains com onents that can roduce arc or s arks. To revent fire or
ex losion, do not install in com artments containing batteries or flammable materials or in locations which
require ignition rotected equi ment This includes any s ace containing gasoline- owered machinery,
fuel tanks, or joints, fittings, or other connection between com onents of the fuel system

2.1.2 Precautions When Working With Batteries
If battery acid contacts skin or clothing, wash immediately with soa 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 s ark or flame in vicinity of battery or Engine.
Do not dro a metal tool onto the battery. The resulting s ark or short-circuit on the battery or
other electrical art may cause an ex losion.
Remove ersonal metal items such as rings, necklaces, and watches when working with a lead-
acid battery. A lead-acid battery can roduces a short-circuit current high enough to weld a ring or the like
to metal, causing severe burns.

3.1.2 Front Panel
3.1.3 ON / OFF Control Switch
The ON/OFF Switch must be in the ON osition when using Remote Control.
3.1.4 Remote Control Terminal
A green two-terminal connector located on the front anel allows remote ON/OFF control of the inverter by a
customer-su lied ON/OFF switch. The connector can be removed from the inverter by ulling the connector
outward. The two u ward facing screws are used to tighten the com ression terminals for attachment of the
signal wire(s). Torque to 4 lb-in max.
Standard O eration (Not using remote control): The inverter is shi ed with a jum er connecting terminals Vout
and Vin. With the jum er in lace (remote control not being used) the inverter is fully functional using the
ON/OFF Control Switch located on the front of the inverter.
Single Wire Remote Control
Remote Control via customer-su lied SPST switch: If it is desired to remotely control the inverter from a
customer-su lied remote switch, remove the jum er connecting terminals Vout and Vin. Su ly 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.
A common remote control arrangement uses a "hot in run" circuit from the vehicle fuse anel for the voltage
signal. This arrangement automatically turns the inverter ON when the vehicle is running and automatically turns
the inverter OFF when the vehicle is turned OFF.
Vin Details
Vin will draw a roximately 0.15 am s continuous while holding the inverter ON. If Vout is not used as the remote
control signal, use a 5 am fused circuit for the Vin remote control signal.
Vout Details
When using Vout as the remote control voltage source, install a 2 am fuse within 12” of the inverter.
The inverter will be damaged if Vout comes into contact with battery negative

3.1.7 Rear Panel
3.1.8 Fan
Do not obstruct the rear fan exhaust or front ventilation intake o enings. Allow at least 3 inches of clearance for
airflow.
3.1.9 DC In ut Terminals
DC In ut terminals are Anderson Power Claw for use with Anderson PP75 Power ole Connectors. Included
se arately are two Anderson #1300 DC In ut Connectors with #5900 Contactors for use with 6 GA wire and
#5912 Bushings for use with 8GA wire.
Connect DC In ut Terminals to a 12v battery (24v battery for 24v units). (+) is ositive,(-) is negative. Reverse
polarity connection will blow the internal fuses (cannot be replaced) and may cause
permanent damage to the inverter.
3.1.10 Chassis Ground Bonding Lug
Connect Chassis Ground Bonding Lug to vehicle chassis using 12AWG or larger co er wire.
WARNING!
O erating the inverter without a ro er ground
connection may cause an electrical hazard.

4 Installation
4.1.1 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 ractical, usually within six feet, but not in the same
com artment and should rovide adequate ventilation while the inverter is o erating. The location must
be clean, dry and free from road s ray, dri ing 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 out ut
ca acity due to overheating.
4.1.2 DC Wiring Considerations
Do not connect the 12V model to a 24V battery. The unit will be destroyed immediately. O eration
of the inverter without a ro er ground connection may result an electrical safety hazard. Damage caused
by reversed olarity will void warranty.
A DC FUS IS R QUIR D to rotect 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 rotected by a fuse.
B AWAR , as a large number of ca acitors become charged u on com letion of the DC circuit,
TH R WILL B A LARG SPARK when the last battery connection is made. The s ark 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 ex losion.
To minimize electromagnetic radiation that could interfere with sensitive electronics, route the AC out ut
wiring and DC ower wiring with as much hysical se aration as ossible from low voltage wiring such as
audio and video signal wires. Route the DC ositive and negative cables as close together as ossible
and use cable ties to kee them together.
If assing through steel or other ferrous metal walls, the DC in ut cables need to ass through the same
hole to revent causing a transformer effect. If two holes are required, cut a slot to connect the two holes
to revent heating of the ferrous metal.
Proper DC cable size is critical for the erformance and safe o eration 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 dro at maximum inverter ca acity and will insure o timum inverter
erformance. DC cable to be used with these fuse sizes should be minimum insulation tem erature
rating of 105°C and voltage rating of 600V.
DC cables should be as short as ossible.
Do not use the vehicle chassis as the DC negative conductor. The negative cable should be the same
size as the DC ositive cable and should be connected directly to the battery negative terminal.

4.1.4 DC Wiring Installation Procedure
Verify the Power ON/OFF Switch is in the OFF osition before connecting inverter to the battery.
Route the negative DC cable to the battery. Verify cable olarity before roceeding. The fuse will be
blown and inverter may be damaged if the DC cables are reversed. Route the ositive DC cable to
the fuse and then to the battery. Protect cables with loom and use grommets or other a ro riate
means where cables may contact hard, shar edges.
Connect Chassis Ground Bonding Lug to the vehicle chassis and/or earth ground using 12AWG or
larger co er 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 ositive DC in ut cable.)
