Congratulations on purchasing your new GSL Electronics 24V to 12V Reducer/Equalizer/Charger. This product
utilises Switchmode and Microprocessor technology giving you the ability to have a fixed voltage output or
the ability to charge Lead based battery chemistries in the one product. The battery charging can either be
as a straight 12V charger or a equalization charger for a 12V battery in a 24V bank which is being used as a
center tapped 12V supply. The charger provides a safe and fast method of restoring discharged batteries and
maintaining them. This is achieved via precisely controlled Bulk, Absorption and Float charging states. The unit is
fully protected against overload, short circuit, over temperature, battery reverse polarity connection(Charger mode
only), over voltage and with a bulk charge timeout for additional safety. The models are built in a compact and
strong aluminium extrusion which can be easily secured to both vertical and horizontal surfaces. Before starting
the charge cycle the battery voltages are evaluated to detect faulty batteries.
Installation & Safety Precautions:
1. The following connection sequence is to be followed:
Ground, Input, Output and Control.
2. Preferably mount the unit inside the vehicle. Avoid locations where external heat is produced e.g. exhaust
system or where the batteries are located.
3. Choose a position with good ventilation where air can pass freely around the unit.
4. Ensure the unit is protected from water spray and other sources of contamination e.g. oil, grease and dust.
5. Ensure that unit is installed away from any flammable fumes, liquids or materials.
6. During charging process, do not use a naked flame near a battery, due to gases emitted from the battery,
which may ignite and explode.
7. Never smoke or light cigarettes near a battery.
8.Do not place tools on top of battery or allow tools to fall on battery.
9. Always wear eye protection near a charging battery.
10. Ensure a "well" ventilated area is used when testing or re-charging batteries.
11. Ensure ventilation is adequate and venting holes are not obstructed. Inadequate ventilation may over-heat the
unit and cause inefficient operation.
12. If skin or clothing comes into contact with acid, flush the area(s) with water immediately.
Seek medical attention if necessary.
Should product require service, return it to your place of purchase for Warranty Advice.
If the unit is in the following conditions. reset as follows:
- Battery Reversal Protection (Charger Mode Only): If the unit is hooked up in reverse then simply reconnect the
unit as per Fig.1
- Output Over Voltage: If the output over voltage protection has been tripped then there will be no operation from
the unit. Contact supplier or GSL Electronics for Warranty Advice.
- Thermal Protection: For your safety and for the longevity of your purchase, the unit will shut down to protect itself
and your batteries when the unit exceeds it nominal operating temperature. To reset this condition the unit must be
disconnected from the battery for at least one minute to allow cooling and for the microprocessor to reset.
