1. INTRODUCTION Thank you for purchasing the KISAE Abso Charger. With our state of the art, easy to use design, this product will offer you reliable service by providing a multi-stage multi-bank battery charger to charge different types of batteries you have installed in your boat, RV, vehicle or your cabin battery bank. This manual will explain how to use this unit safely and effectively. Please read and follow these instructions and precautions carefully.
2. PRODUCT DESCRIPTION The KISAE Abso Charger includes the items list below. • Base unit (AC1220 or AC1240 or AC1260) • Owner’s manual (P/N: MU IC1210) 3.
the battery. • A KISAE Abso Charger Temperature Sensor (sold separately) is available and is used to connect to one of the battery terminals. It measures the battery temperature and will make small adjustments to the battery charging voltage for better battery charging performance. • If the temperature sensor is not used, you can also manually set the charger to Low, Normal, or High to reflect the environmental temperature for better charging effect.
4. INSTALLING THE CHARGER WARNING: KISAE Technology recommends that all wiring be done by a certified technician or electrician to ensure adherence to the applicable electrical safety wiring regulations and installation codes. Failure to follow these instructions can damage the unit and could also result in personal injury or loss of life.
2 2 2 20’ (6m) #6 / 13.3mm – 80A #2 / 33.6mm – 125A #1 / 42.4mm – 150A • Remove the DC compartment cover by removing the two screws located on the top surface of the unit near the AC wiring compartment. • Keep the connection between the battery and the charger as short as possible. • Connect one end of the positive wire (red wire) to the Bank_1 of charger positive terminal with torque 4.0 ~ 5.0 N-m (35 ~ 45 lb-in) and the other end to the over current protection device, then the DC disconnect device.
5. UNIT OPERATION Understanding the Charger The charger is a three bank battery charger that is capable of charging three battery banks individually. The three battery banks must be the same battery type. For the charging mechanism, if more than one bank is connected to the charger, the charger will charge each individual bank continuously for 15 minutes and then switch to the different bank(s) and cycle until all battery banks reach float mode.
The charger will automatically restart the charging cycle in Bulk stage if the battery is discharged to 12.5V. Also, after seven days, the charger will automatically restart the recharging cycle to refresh the battery. Understanding the Battery Temperature Functions: Optional Battery Temperature Sensor KISAE Part Number #BTS-10K is highly recommended with the charger to protect your battery and provide better charging voltage accuracy.

Understanding the Priority Bank Charging Function The charger comes with a unique ‘Priority’ bank charging function that allows the user to force the charger to fully charge one of the three banks to float mode before it switches to other banks. This function will only work for GEL, AGM, Flooded, and Lithium battery type setting only. To set this function, see Appendix A in details.
E01 Unit shutdown due to low AC Input (< 85 +/- 5Vac) E02 Unit shutdown due to high AC Input (>270 +/- 5Vac) E03 E04 Battery is connected backwards Charger Internal temperature is too high and unit has shutdown. Unit will automatically recover when the unit cools down. Inlet temperature is high >60°C (140°F) and unit has shutdown. Unit will automatically recover when inlet temperature is reduced to <45°C (113°F). High battery temperature >70 °C (158°C) is sensed by the BTS. The unit will shutdown.
