® INCORPORATED Installation Introduction Thank you for purchasing the Vanner ITC-Series inverter/charger system. We are confident that you will be satisfied with its 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 for the ITCSeries inverter/charger system.
® INCORPORATED Installation System Features Inverter The inverter consists of a sine wave inverter that supplies power when AC loads are applied. Depending on ® your model, the inverter develops 2100, 3200 or 3600 watts of continuous power. Using TruSine technology, a very high quality sine wave is produced. Total harmonic distortion (THD) is less than 4.0 percent.
® INCORPORATED Installation (Vanner Part # D011339) must be installed in it’s place to insure that debris does not enter the unit through the opening and to maintain proper airflow through the unit.

® INCORPORATED Installation DESCRIPTION OF OPERATION Inverter The System ON/OFF Switch, located on the front panel, allows the user to turn the system power ON and OFF and to reset the system after a fault. The Charger ON/OFF and Inverter ON/OFF buttons, located on the Control/Display Unit enable or disable the Charger or Inverter Functions. The corresponding light next to Inverter/Charger buttons will be steadily on when the unit is in the Inverter or Charger mode.
® INCORPORATED Installation Battery Charger The battery charger’s advanced design incorporates an automatic, multi-stage charger. This design enables the unit to automatically charge batteries, which maintains the battery’s integrity and reduces the likelihood of premature battery failure. In addition, the battery charger can utilize the remote battery temperature sensor to reduce the float voltage based on battery temperature.
® INCORPORATED Installation ‘Absorption Charge Amps’ setpoint and the Equalize Voltage 15.5 (30.0) 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 levels, which improves battery performance and extends battery life. Consult the battery manufacturer for their recommendation regarding how often the Equalize Cycle should be performed.
® INCORPORATED Installation GenStart It should be noted that the Generator Start Operation is designed to minimize the generator run time, so at the present set points there is no Absorption stage per se. Therefore, the batteries must be periodically conditioned by leaving the generator on, or charging them with another system. The GenStart feature is designed for use in installations where a generator is used to provide AC input power for battery charging.

System ON/OFF Switch Use this rocker switch to turn the system ON and OFF and to reset the system. This switch is located on the front panel of the system. If placed in the “OFF” position, this switch will override the operation of a remote ON/OFF switch connected to terminals 7 and 8 of the Options connector shown in Figure 3-1 – Customer Terminations.

® INCORPORATED DC Cable Size Max.
® INCORPORATED Installation C)Put lugs (For the appropriate wire size called out in Table 4-1) on the ends of the Positive and Negative DC Cable ends with the appropriate terminals. Be sure that all cable strands are completely in the lug to avoid shorting to another conductor. D)Insert the black, negative (-) cable end through the strain relief and onto the negative terminal threaded stud, and tighten to 275 inch-pounds. .
® INCORPORATED Installation with code. Make certain to route the Signal wires out of the provided port (lower most on the right side of the unit). This is to insure that there are no problems that may arise from the poor insulation properties of most signal level wire. Make certain that the auxiliary contact and option wiring are routed below the barrier, and the AC Power Wires above the barrier. Step 1: Connect the AC output. Remove the front cover to expose the AC input and output terminal strips.
® INCORPORATED Installation A) With shore power applied, press the Charger ON/OFF button to enable the Charger (if not enabled). The Charge LIGHT should come on and the batteries should begin charging. Remember to reduce the loads on the unit since the APM will limit the available power to the charger based on its settings. B) Disconnect the shore power – the unit should transfer back to Inverter mode. C) Discharge the battery by placing the AC load on the system and operating the inverter.
® INCORPORATED General Information Modified Sine Wave Inverter Modified sine wave inverters are sometimes called “quasi sine wave inverters” or “modified square wave inverters.” Modified sine wave inverters generally cost more than square wave inverters because they contain additional electronic circuitry to produce true RMS regulated AC output.
® INCORPORATED General Information This rule of thumb can be used to estimate the minimum alternator size required for your application. It may also be used in calculating the minimum size battery required when operating from an alternator and battery combination; a photovoltaic panel and battery combination; or when operating from battery alone. The following examples should help to clarify the use of this rule of thumb.
® INCORPORATED General Information 100 AH battery is specified to be able to deliver 5 amps for a period of 20 hours. If the discharge current were increased to 25 amps, the capacity will be reduced to approximately 75 AH (25 amps x 3 hours = 75 AH). Operating temperature: A battery becomes less efficient at lower temperatures. Most battery manufacturers specify the battery AH capacity at 80° F.
® INCORPORATED General Information Step 3: Calculate the total watt-hours needed by adding together the watt-hours of each appliance. Step 4: Find the amp-hours consumed by dividing the total watt-hours found in step 3 by 10 for 12 volt DC systems or by 20 for 24 volt DC systems. Step 5: Multiply the amp-hours consumed by 2 (for 50% depth of discharge) to get the battery amp-hour capacity desired.
® INCORPORATED General Information 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. An improperly adjusted battery charger may cause damage to your batteries! The maximum charging current for a battery is usually equal to 20% of the battery's Amp hour capacity (“C Rating”) for lead acid batteries, and 50% of the battery's C for gel cell batteries.
® INCORPORATED General Information MAINTENANCE & TROUBLESHOOTING 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. Check to insure that all AC and DC wiring is secure and connections are tight and corrosion free. 2.
