User Manual

Keep this manual in a safe place for quick reference at all times.

This manual contains important safety and operation instructions for correct use of the battery charger. Read through the

manual and pay special attention to the markings and labels of the charger, battery and equipment connected to the

battery system.

Pay special attention to these two types of notices used in this manual.

WARNING:

Failure to heed this warning may cause injury to persons and damage to Equipment.

CAUTION:

Failure to observe this warning may result in damage to equipment and improper functioning of the Charger.

WARNING:

● The charger is designed for in-door use. Protect the charger from ingress of water.

● This charger is made to charge only properly sized lead acid batteries.

● Don't recharging non-rechargeable batteries.

● Charging other types of battery or under-sized lead acid batteries may cause fire or explosion.

● Install the charger in accordance with all local codes

● Do not use the charger if it has been dropped or damaged.

● Do not remove casing of the charger, there is no user-serviceable parts inside.

● Do not charge the battery on boats. Remove the battery and charge on shore.

● Never attempt to charge a frozen battery

● Never attempt to charge a damaged battery.

● Wear protective goggles and turn your face away when connecting or disconnecting the battery.

● Never place the charger on top of a battery.

● Never smoke, use an open flame, or create sparks near battery or charger during normal charging operation as

batteries may give out explosive gas.

● Do not charge batteries in an enclosure (box- in) due to possible explosion of entrapped explosive gas.

● Use of accessory not recommended may cause risk of fire, electric shock.

● Disconnect the mains supply before connecting or disconnecting the links to the battery.

● If the charger does not work properly or if it has been damaged, unplug its AC and DC connection.

CAUTIONS:

● Refer to battery manufacturer’s specific recommended values for battery type settings and float voltage setting.

● Fix the charger to a solid support via three grooves at the flange of chassis, with three screws or nuts.

● Ensure all ventilation ports are not obstructed for efficient fan cooling, keep loose soft material or paper off at the vent

holes of the charger.

● During charging, the battery must be placed in a well ventilated area.

● If longer output charging cord is required, make sure the diameter is adequate for the current in given cable length.

INTRODUCTION

Congratulations on purchasing our new Multi-Stage (IU0U) Switching Mode Smart Battery Charger.

This software based MCU control 7 stage smart charger is designed with user friendly features and software plus
hardware protection. It is a set, connect and forget charger that ensures complete recharge of your battery.

Your battery can be connected indefinitely to the charger which will enter into energy conservation mode to prevent over
charging and save electricity bills. The battery state of charge and temperature are closely monitored, updated and
logged by the MCU and the remote temperature sensor mounted on the supplied charger cable and heavy duty battery
clamps.

Though the charger basically is engineered to charge high capacity battery/ banks, it can be made to charge much
smaller battery by selecting the right reduced output setting. This charger can also be converted to a fixed voltage power
supply with one simple concealed which setting.

The extensive protection with alarm and LED indications including the thermostatic decrease of charging current to shut
down ensure a durable working life span even in harsh conditions for the charger and the battery. There are selections for
WET, AGM, GEL and Calcium-Calcium battery types. Special evaluation, conditioning charging profiles are made for the
WET type battery so to recover deeply discharged WET lead acid battery.

There is a Power Supply (PS) mode to provide a constant voltage DC power 13.3V to the external load connected to the
battery and at the same time without over charging the battery.

Almost all the protections are controlled by the Micro-Processor. On start up, the chargers run a series of self tests on the
protective functions, displays and critical components like the cooling fan.

Intended Use:

All Automotive, Marine, Mobile Home, Electric Scooters, Golf Carts, Solar, Deep Cycle, UPS Standby, Industrial &
Commercial Applications.

The LCD will display the battery type you selected after restart the charger.

WET : Flooded Type lead acid batteries (to which water can be added) Automotive or Deep Cycle
AGM/GEL : Sealed type (VRLA), AGM-GEL, Maintenance Free, Automotive or Deep Cycle lead acid batteries
Calcium-Calcium : Sealed type (VRLA) Lead Acid batteries with Calcium content Automotive or Deep Cycle
Power Supply : to provide a constant voltage DC power 13.3V to the external load connected to the battery and at
the same time without over charging the battery

B1. Recommended Battery Capacity

The following minimum AH capacities are a generalized suggestion, some batteries can take higher charge current,
check with battery manufacturers for charging batteries with smaller capacity.

C. Battery Charger Installation and Connection

Observe the warnings & safety precautions before rushing to install and operate the charger.
Check battery condition, fill up cells for wet battery, clean battery poles.
Secure the battery charger in a well ventilated place, make sure the mounting surface is flat and without soft covering
material or loose paper sheet. The air intake is at the left side and air outlet at the right side. Make sure both intake and
outlet are not blocked. Never place charger on top of battery.

Plug in the AC mains. The LCD will display “Welcome” and unit software version and then go through a self-test.
The cooling fan spins at full speed for 3 seconds and a “Beep” sound by means of Self-Testing.
