Vanner 20-1000TUL Inverter
Section1:Introduction
Thank you for purchasing a Vanner 20-1000TUL Power Inverter for your emergency
vehicle. We are confident you will be satisfied with its performance.
Vanner products are designed and manufactured by skilled professionals using the
highest standards in workmanship, guaranteeing excellent performance and reliability
for your emergency vehicle. With minimum maintenance and care, you can expect
years of trouble-free service from your Vanner product.
The 20-1000TUL is a 12 VDC to 120 VAC inverter with a transfer relay and Ground
Fault Circuit Interrupter (GFCI) protected AC output. This unit is equipped with an
AC line cord for AC input power (shore/utility power) and a receptacle with a GFCI
for AC output. This enables you to plug AC loads directly into the inverter. The DC
cables have quick connectors to facilitate installation and pre-wiring of emergency
vehicles.

Functionality
Inverter
The 20-1000TUL converts battery power to 1050 Watts of 120 VAC modified sine
wave power to operate vital emergency vehicle equipment. The unit is easily connected
to the positive and negative posts of a battery system with appropriate fusing, and
when turned ON, produces 120 VAC True RMS power.
The inverter also has an energy-saving feature called Load Demand. With this feature,
the inverter output is pulsed, significantly reducing the current draw from the battery
until a demand is made on its output. Continuous output of 120 VAC resumes when a
load greater than 5 Watts is applied. The load demand feature can be disabled with the
Setup Switch on the front panel.
A built-in transfer relay senses AC input to the emergency vehicle (shore/utility power)
and connects the AC input directly to the GFCI receptacle. At that time, all equip-
ment which was operating on the inverter is now powered by the AC shore line.

Section2:Installingthe20-1000TUL
Unpacking the Inverter
Inspect the shipping container and equipment for loose or damaged parts.
` If any damage is found, immediately notify the freight carrier.
Installing the Inverter
Step 1: Turn the inverter OFF/disconnect power to the wiring harness.
Make sure power to the vehicle wiring harness is disconnected. Verify
that the inverter is turned OFF by checking that the ON-OFF/RESET
Inverter Switch is in the OFF-RESET position.
(The button should NOT be pushed in.)
Step 2: Select a location for the unit.
An ideal installation location has the following characteristics:
• Close to the battery (within six feet using #2 AWG wire)
• Protected from the weather
• Well ventilated
Step 3: Route DC input cables.
Route the negative and positive DC input cables from the inverter (through
the quick connector) to the battery. If required, protect cables where they
contact hard, sharp edges.
Step 4: Install in-line fuse.
Install an in-line Bussman ANN 125 or equivalent fuse (Vanner p/n 03640-
fuse and 03637-fuse holder) in the red, positive DC input cable between the
battery and inverter, within 18 in. of the battery or DC wiring bus system.
Step 5: Connect Bonding Lug.
Use a AWG #8 or larger copper conductor to connect the chassis bonding lug
to the vehicle chassis and/or earth ground.
Step 6: Connect the inverter to the battery.
Connect the black, negative DC input cable from the quick connector to the
battery negative (-) terminal. This battery negative terminal is usually where
the battery negative connects to the engine block or frame.
Connect the red, positive DC input cable from the quick connector to the
fuse of the battery positive (+) terminal. This battery terminal is usually
connected to the DC electrical system at the load side of the Battery
Disconnect Switch.

Step 7: Select Load Demand option.
Select Load Demand option, if desired, using the proper switch position on
the front panel Setup Switch. With Load demand ON, the inverter conserves
battery energy and operates only when a load greater than 5 Watts is applied.
Step 8: Connect the AC loads.
Connect the AC loads to the inverter GFCI receptacle. Any time AC power is
applied to the AC input (shore/utility power), it will pass through this GFCI
receptacle.
Step 9: Verify installation.
Verify all connections are tight and secure for maximum performance.

Section3: InstallingtheIFM1InterfaceModule
This section describes the installation of the optional Vanner Model IFM1 Interface
Module. Refer to the information provided in the IFM1 Interface Module Owner’s
Manual for more information on installing the inverter and interface module in a
vehicle rewired or retrofitted for the 20-1000TUL.
If you are installing a new 20-1000TUL unit, you will need the interface module only
if you are using the inverter status panel (p/n D06638), Remote Switch (p/n D06781),
or if you require the inverter lockout feature.
Installing the IFM1 Interface Module
Step 1: Mount the Interface Module.
Mount the interface module in the vehicle’s existing 12 V electrical system
wiring harness with #8 screws. Select a physical orientation best suited for
your application environment; however, it must be within the 2ft Interface
Cable length to the inverter. Additionally, the unit should not be installed
with pin connections facing upward.
Step 2: Connect the Inverter to the Interface Module.
Install the 2 ft. interface cable by plugging it into the remote RJ-11 connector
on the 20-1000TUL and the J1 connector on the IFM1 Interface Module.
Step 3: Connect the Battery Disconnect Switch.
Connect the +12 V lead from the Module Disconnect Switch circuit to the
inverter lockout Pin 1 (ignition switch or battery disconnect switch). The
+12 V lead from the Battery Disconnect Switch must be fused with an in-line
fuse or circuit breaker of 2 Amps or less. See Figure 2.
Step 4: Wire the Remote Switch (p/n D06781) to Pins 2 through 5.
Red to Pin 2, Black to Pin 3, Green to Pins 4 and 5. If no remote switch is
used, two jumpers must be installed. The first jumper connects Pin 2 to Pin
3, the second jumper connects Pin 4 to Pin 5. See Figure 2.
Step 5: Connect the Inverter Remote Status Display Panel (Optional).
Connect the gray, green, and red wires from the inverter panel, through the
OEM harness, to the IFM1 Module, Pins 6 (grey), 7 (green), and 8 (red).

Section4: InstallingtheInverterRemote StatusDisplayPanel
The Inverter Remote Status Display Panel (p/n D06638) contains separate, red and
green LED indicators. The green indicator light signifies the inverter is On or in
Standby mode. The red, Fault LED indicator shows problems such as over tempera-
ture, output overload, or low battery. The panel has a sealed overlay which mounts
easily on a flat surface. A 12-in. pigtail harness is included for easy installation. Use the
following procedure to install the Inverter Remote Status Display Panel.
Step 1: Select a location for the panel.
Identify the desired location for the inverter panel.
Step 2: Identify wires for installation.
Identify the gray, green, and red wires on the inverter panel and vehicle's
electrical system wires that will connect to the IFM1 Interface Module.
Step 3: Splice and arrange wires.
Splice together like-colored wires from the vehicle's electrical system to the
status panel using an insulated butt splice or equivalent. Carefully arrange the
wires such that the panel mounts flush against the surface to which it is
mounted.
Step 4: Secure panels to surface.
Mount the panels using #8 screws through the four holes in the panel.

Use the following instructions to operate the 20-1000TUL Inverter.
Step 1: Install the 20-1000TUL unit.
Completely install the inverter and charger using the instructions provided in
Section 2 of this manual.
Step 2: Apply an AC load.
Apply an AC load with AC input power present. The AC load is run directly
from AC input power. The ON-OFF/RESET Inverter Switch does not affect
the inverter's AC output when shore power is present.
Step 3: Turn on the inverter Remote Switch.
Step 4: Apply shore power to the 20-1000TUL/Ambulance shore line connection.
Push the ON-OFF/RESET Inverter Switch to the ON position. When
powered by the AC power, the ON lamp flashes, indicating that the inverter
is standing by.
Step 5: Verify Power.
Apply an AC load, such as a shop light or drill. The AC load is run directly
from AC input power.
Step 6: Observe the inverter operation.
Remove the shore line connection from the emergency vehicle. The unit will
automatically switch to Inverter mode and operate the AC load using battery
power. When shore power is restored, the unit examines the AC input for five
seconds and then switches the loads back to run directly from AC input
power.
With the ON-OFF/RESET Switch in the ON position, a double flash of the
ON light indicates the load demand is turned ON and the load is less than
5 Watts.
