System Features and Specifications General Description The ITC-Series system consists of a DC to AC true sine wave inverter, a 12-volt battery charger, an automatic AC transfer switch, and a microprocessor based controller. An important feature of this system is the ITC-Series Control/Display Unit user interface.
Auto-Throttle based on battery voltage of 12.3 VDC. The GenStart/Auto-Throttle turns off when the battery charging current falling below 10 amps. Call Vanner at 1-800-ACPOWER for technical assistance in selecting the proper auto-throttle kit to use for this application.
Dual Purpose – Indicates that a fault has occurred in the inverter or Charger – Could be a Over Temperature shutdown, Low/High Battery Shutdown, Power Stage Fault, or Input AC fault Equalize Button This is used to enable the equalization cycle on the battery during charging.

5 minutes if Auto-Restart is Enabled and the fault condition no longer exists. 2. Manual restart You can manually restart the system after the fault conditions are removed. Reset the inverter by turning the System ON/OFF Switch OFF and then ON. ITC-Series Inverter Page 13 Owner’s Manual 8/07/03...
Equalize Voltage 15.5 VDC setpoint. The Equalize Charge Cycle provides a deliberate overcharging of the battery to remove sulfate, which accumulates on the battery plates through normal use. Equalizing returns battery cells to equal performance ITC-Series Inverter Page 14 7/18/03...
The Bulk charging current is checked every 4 minutes, therefore the minimum generator ON time is 4 minutes. The contacts are NEC Class 2, rated 2 amps at 12 VDC. It should be noted that the Gen Start/Auto-throttle contacts are shown in Figure 1.4-4 Customer Terminations, ITC-Series Inverter Page 15 Owner’s Manual 8/07/03...
The graphic to the left indicates the factory defaults. Switches 1 through 4 show an 80-amp charger. Switches through indicate 30-amp automatic power management. Switch 9 has selected Wet Cell battery configuration. Switch number 12 indicates “Master” 10 11 12 display/control unit. ITC-Series Inverter Page 16 7/18/03...
3.3 Front Panel Control/Display Outlet This is a RJ-11 (6-Wire) jack (P5) for communications with the Control/Display Unit. A secondary Control/Display unit can be plugged into the P6 jack who would be configured as a slave. ITC-Series Inverter Page 17 Owner’s Manual 8/07/03...
Figure 3-1) together. This will actuate an internal relay that turns the control power on. The Power On/Off switch on the front panel defeats this remote switch. In addition, a terminal for a remote LED indicator is provided (terminal 6) with a current limiting resistor integral to the circuit. ITC-Series Inverter Page 18 7/18/03...
4.3 AC Wiring Preliminary Considerations 1. Output and Input Voltages The ITC is designed to operate with an AC Output Voltage and AC Input Voltage of 120 VAC, 60Hz. 2. AC Wire Size ITC-Series Inverter Page 21 Owner’s Manual 8/07/03...

Connect Bonding Lug. Use a 8 AWG or larger copper conductor to connect the chassis bonding lug to the chassis of the vehicle, the installation’s grounding system, or to earth ground. Step 4: Verify Installation. Verify all connections are tight and secure for maximum performance. ITC-Series Inverter Page 22 7/18/03...
Installation 4.4 System Start-up and Testing Step 1: Completely install the ITC-Series Inverter/Charger following the system design considerations and instructions provided previously in this manual. Step 2: Place the System Power On/Off switch located on the front of the inverter in the OFF position.
AC power that the inverter can produce. It is often specified as the watts (or volt/amps) that can operate a resistive load for two or three seconds. Sometimes this is specified in AC amps because the inverter ITC-Series Inverter Page 24...

The most important detail of this system is the alternator output rating. The continuous output of the alternator must be at least as much as the total DC current draw on the system. The ITC-Series Inverter Page 27...
5.7 Battery Charging Guidelines CAUTION The following information on battery charger setup adjustments should be used as guidelines only. Vanner strongly recommends that you contact the manufacturer of your batteries to obtain the specific charging setup values for the type and model of battery you are using. This is because battery charging parameters such as bulk, absorption, float and equalize voltages vary from one manufacturer to another, and that gel cell batteries have different parameters than wet lead acid batteries.
General Information 6 MAINTENANCE & TROUBLESHOOTING 6.1 Preventative Maintenance There are no user serviceable components inside the ITC-Series Inverter/charger. For service refer to Vanner Incorporated or other qualified service personnel. Maintenance Items: For continued reliability and safety, a monthly maintenance program should be implemented to include the following: 1.
