Definitions
- 10 - IQ SERIES OWNERS MANUAL
1.5 Definitions
1.5.1 Quasi Sine Wave:
Quasi Sine Wave Inverters are sometimes called "modified sine wave inverters" or "modified square wave
inverters." Quasi sine wave inverters produce an AC output wave different from the power produced by
the electric utility companies and rotating generators. Although this waveform has a higher peak voltage
than do square wave inverters, its peak voltage is not as high as a pure sine wave. Therefore, AC loads
containing power supplies might not always operate properly on the quasi sine wave inverters.
1.5.2 Load Demand Feature and Load Demand Mode:
The Load Demand Feature is an energy conserving feature which allows the inverter to enter the ‘Load
Demand Mode’ whenever the inverter is ON and the AC load has been less than 5 watts for
approximately 5 seconds. While in the ‘Load Demand Mode’ the inverter does not produce 120 volts AC
but instead produces pulses of reduced AC voltage, which the inverter uses to look for a load. When an
AC load greater than 5 watts is sensed, the inverter will turn fully ON to produce 120 Volts AC. The ‘Load
Demand Mode’ is often also described as ‘stand-by mode’ or ‘sleep mode’. While in the ‘Load Demand
Mode’ the inverter consumes approximately 140 milliamps of 12 volt DC power.
The Load Demand Feature can be turned OFF by setting Selector Switch 2 to the OFF position. This will
cause the inverter to remain fully ON, producing 120 Volts AC, whenever the inverter switch is ON and
regardless of AC load. It is desirable to do this when the device being powered draws less than 5 watts.
An example of such a device is a plastic pipe fusion machine, which draws less than 5 watts during the
‘coupling cooling time’. With the Load Demand Feature turned OFF and operating no AC load the
inverter consumes approximately 1.8 amps of 12 volt DC power.
1.5.3 Automatic Transfer Switch:
The Transfer Switch is a standard feature provided on all IQC models. The Transfer Switch automatically
allows input power, from an external AC power source such as shore power or a generator, to pass
through the inverter output circuit and be used to operate inverter loads.
1.5.4 Automatic Power Management:
The IQC’s AC Input 1 is the source of AC power for battery charging and also may provide passthrough
power for AC loads. The Automatic Power Management (APM) circuit monitors total AC amps on the
IQC’s AC Input 1 and reduces the battery charger’s AC power consumption when necessary so that total
AC1 amps do not exceed the APM Setting. The APM circuitry does not limit AC power passing through to
AC loads. The default APM Setting is 30 amps. By using the optional D07934 Remote APM Panel the
APM Setting can be adjusted to lower values. (More details can be found in the Automatic Power
Management description of operation.)
1.5.5 Ambulance Mode:
The primary purpose of Ambulance Mode is to prevent the inverter from coming ON and running down
the ambulance’s battery when the shore power cord accidentally becomes unplugged.
In Ambulance Mode the IQC performs similar to Vanner’s 20-1050CUL Ambulance inverter/charger. The
charger will turn ON and shore power will pass through as soon as shore power is connected to AC1.
(The ON/OFF Switch must be in the RUN position but the charger does not need to be manually turned
ON.) When shore power is disconnected, the inverter will not turn ON until the ON/OFF Switch, or remote
switch, is manually pushed to the Start position.

Important Safety Instructions
IQ SERIES OWNERS MANUAL - 11 -
If Ambulance Mode is not selected the inverter/charger will function in Standard Backup Mode. In
Standard Backup Mode the charger will not turn itself ON when shore power is connected. The inverter
must already be ON or the charger must be ‘started’ by pushing the ON/OFF Switch to the Start position.
In Standard Backup Mode, when shore power is disconnected the inverter will automatically come ON.
1.6 Important Safety Instructions
This manual contains important safety and operating instructions for the Vanner Power Group “IQ Series”
Power Inverter and Inverter/Charger System as prescribed by Underwriters Laboratory (UL). The IQ
Series Inverter and Inverter/Charger Family is listed as compliant with UL 458 (only if the UL/CUL
symbol is on the front of the unit), Power Converters/Inverters and Power Converter/Inverter Systems
for Land Vehicles. The Vanner Power Group “IQ Series” also is listed to the Canadian National Standard
CSA –C22.2 No. 107.1 –1951.
SAVE THESE INSTRUCTIONS
WARNING This equipment employs components that tend to produce arcs and sparks. To prevent
fire or explosion, DO NOT install in confined areas or compartments that contain batteries
or flammable materials.
WARNING Risk of electrical shock. Use only the ground fault circuit interrupter (GFCI) receptacle(s)
or circuit breaker(s) specified in the installation and operating instructions supplied with
this inverter. Other types may fail to operate properly when connected to this equipment.
CAUTION Read owners manual BEFORE wiring or powering up.
CAUTION DO NOT cover or obstruct ventilation openings. DO NOT mount in zero-clearance
compartments. Overheating may result which may diminish system capacity.
NOTICE The output of this device in not sinusoidal. The IQ SERIES inverter has a total harmonic
distortion of 34.6 percent and maximum single harmonic of 24 percent.
1.7 General Precautions
1. Do not expose the Vanner IQ series Inverter to direct water spray or snow.
2. To reduce the risk of a fire hazard, do not cover or obstruct the ventilation openings.
3. Do not cover or obstruct ventilation openings. Do not install this unit in a zero clearance compartment.
The result may be overheating which may diminish performance.
4. To avoid the risk of fire, electric shock, or injury to persons, do not use attachments not
recommended or sold by the Vanner Power Group
5. Vanner recommends that all DC and AC electrical wiring be performed by a certified electrician or
technician to ensure compliance with all proper national and local wiring regulations.
6. To avoid a risk of fire and/or electric shock, always verify wiring connections are in good electrical
condition. All external conductors must use proper wire size to avoid dangerous overheating or
diminished performance.
7. If the Vanner inverter system has been dropped or damaged in any way, do not operate until its
operation has been verified to be safe by a qualified technician.

Important Safety Instructions
- 12 - IQ SERIES OWNERS MANUAL
8. To reduce the risk of electric shock always disconnect the AC and DC connections to the Vanner
Inverter system before attempting any maintenance. Simply turning the unit off does not prevent
electric shock.
9. The Vanner “IQ Series” inverter system must be properly grounded in accordance with local and
national codes and ordinances before operation. For most installations the negative (ground)
conductor should be bonded to the grounding system at one and only one point in the system.
10. Do not disassemble the IQ Series Inverter/Charger; see the service section of this manual for
instructions on obtaining service for the IQ Series Inverter/Charger. Attempting to service the unit
yourself may result in a risk of electrical shock or fire
1.8 Explosive Gas Precautions
1. This equipment contains components, which tend to produce arcs 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.
2. Working in the vicinity of a lead-acid battery is dangerous. Batteries generate explosive gases during
normal battery operation. To reduce the risk of battery explosion, follow these instructions and those
published by the battery manufacturer and the manufacturer of the equipment in which the battery is
installed.
1.9 Precautions When Working with Batteries
1. Always have someone within range of your voice to come to your aid when you work near a lead-acid
battery.
2. Have access to plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or
eyes.
3. Always wear complete eye protection and clothing protection. Avoid touching eyes while working near
batteries.
4. 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.
5. NEVER smoke or allow a spark of flame in the vicinity of batteries. Gases produced by batteries are
explosive.
6. Be careful when working with metal tools around batteries. Potential for spark exists or short-circuit
of the battery or other electrical part that may cause an explosion.
7. Never charge a frozen battery. Attempt to warm battery above 32 degrees F before charging.

2.19 (19) 120 VOLT AC WIRING
CAUTION: BE SURE THE INVERTER IS TURNED OFF AND ALL EXTERNAL SOURCES OF
POWER ARE TURNED OFF BEFORE ACCESSING THE AC INPUT/OUTPUT WIRING.
General
AC input and output wires are to be routed through the three strain relief cable clamps located on the right
side of the unit.
The installer should verify that all AC circuits connected to the unit output are an insulated neutral type as
required by the National Electrical Code (NEC) article 551.
Refer to local codes for correct AC wire size appropriate for your inverter system and loads.
Ground Fault Circuit Interruption
Some installations require the installation of Ground Fault Circuit Interrupter (GFCI) type circuit breakers
in the AC distribution system. Because the output waveform of the inverter is not the same as that
supplied by a generator or the utility, some GFCI devices do not function properly. The following list of
GFCI circuit breakers have been tested and function properly with this inverter system.

** Note: If GFCI trips and the inverter is in Load Demand mode the GFCI may not reset until you toggle
inverter off and back on then you will have 5 seconds to reset GFCI before unit goes back into Load
Demand mode again or you can disable Load Demand mode via dipswitch, if available.
IQ Models (Inverter only)
General AC1, AC2 and AC3 are all output circuits.
AC1 AC output circuit protected by 20 amp circuit breaker CB1.
AC2 AC output circuit protected by 15 amp circuit breaker CB2. (On inverter-only
models, the built-in GFCI receptacle receives its power from AC2.)
AC3 AC output circuit protected by 30 amp circuit breaker CB3.
IQC Models (Inverter/Charger)
AC1 This is the primary AC input circuit and is protected by 30 amp circuit breaker CB1. Input voltage
and frequency are monitored for proper tolerance at all times. Input power supplied to AC1 is
used for battery charging, and is used for pass-through to AC3 if power is NOT present on AC2.
Note: Be careful that the AC input power required for battery charging combined with the pass-
through power required for the AC loads does not overload the shore power AC source.
The battery charger will draw approximately 30 AC amps from shore power through AC1 when
the 12 volt charging output is 120 amps. AC input amps to DC output amps remains
approximately the same ratio. The charger will draw proportionally lower AC input amps from

Installation
- 20 - IQ SERIES OWNERS MANUAL
shore power when the charger output amps are lower. Read the Automatic Power Management
section in this manual which applies only to AC1. If desired, use the optional Remote Automatic
Power Management (APM) Panel, Vanner part number D07934, to reduce the maximum AC
input amps the charger can draw.
AC2 Secondary (and optional) 30 amp AC input circuit which is used only for pass-through to AC3.
This allows the full 30 amps input on AC1 to be used for battery charging. AC2 accepts input
power only when AC1 is receiving AC input power.
Caution: AC power supplied to AC2 MUST BE IN-PHASE with the AC power supplied to
AC1. (When two circuits are in-phase there will be zero AC volts between AC1 hot and AC2
hot.) The transfer switch components will be destroyed if AC1 input and AC2 input are not
in-phase. (If not in-phase the multi-meter would show 240vac between AC1 hot and AC2
hot.)
AC3 AC output circuit protected by 30 amp circuit breaker CB3. (On charger models, the built-in GFCI
receptacle receives its power from AC3 via CB2.)
Notice: 1. When the inverter/charger is connected to an external power source, the internal circuit
breakers (CB1, CB2 and CB3) are considered supplemental and do not qualify as “branch rated”
circuit breakers. External AC circuits carrying power to and from the unit must conform to
National Electric Code and any other applicable codes.
2. The Automatic Power Transfer Switch switches both hot and neutral. For safety purposes the
inverter output neutral (terminal #8) is connected to the inverter chassis ground only when the
unit is in inverter mode. This is a requirement of the National Electric Code for all systems of this
type that neutral should be connected to ground only at the source of AC power, which is the
inverter when in inverter mode. When an external AC input (shore power, generator) is available,
the IQC Transfer Switch system breaks the connection between neutral and inverter chassis
ground. The neutral-to-ground connection for pass-through power is then provided by the AC
input source.
2.20 (20) DC INPUT WIRING COMPARTMENT
All Models
The DC wiring enclosure is located on the top right side of the inverter and contains 5/16 “
diameter studs to permit connection of two cables from the battery.
BE AWARE that, 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.
2.21 (21) GROUND WIRING LUG
All Models
This is a compression type terminal requiring only a flat blade screwdriver to make the
connection. This terminal has been provided for safety to prevent possible shock hazards.
Connect a #8 AWG minimum size wire to this terminal and then to the vehicle chassis ground or
to earth ground.
