1. SAFETY
IMPORTANT: To reduce the risk of a battery explosion, follow these instructions and those published by the battery manufacturer and the
manufacturer of any equipment you intend to use in the vicinity of the battery. Remember to review warning marks on all products and on
engines. Modern vehicles contain extensive electronic systems. Check with the vehicle manufacturer for any specic instructions regarding the
use of this type of equipment on each vehicle. No liability will be accepted for damage/injury where this product is not used in accordance with
all instructions.
1.1. ELECTRICAL SAFETY
WARNING! For automotive 12 volt use only. DO NOT use with dry cell or lithium batteries.
WARNING! It is the user’s responsibility to check the following:
Check all electrical equipment and appliances to ensure that they are safe before using. Inspect power supply leads, plugs and
all electrical connections for wear and damage.
Electrical safety information. It is important that the following information is read and understood.
1.1.1. Ensure that the insulation on all cables and on the appliance is safe.
1.1.2. Regularly inspect cables and plugs for wear or damage and check all connections to ensure that they are secure.
1.1.3. Inadequate ventilation may over-heat the charger and cause ine󰀩cient operation.
1.1.4. The battery charger contains hazardous voltages. There are NO user serviceable parts / components inside. To avoid any hazard
this unit must be repaired or replaced by the vendor or equally qualied person.
8DO NOT expose the unit to sustained moisture or extreme weather conditions.
1.2. GENERAL SAFETY
▲DANGER! BE AWARE, LEAD-ACID BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION.
FOR THIS REASON, IT VERY IMPORTANT TO READ AND FOLLOW THESE INSTRUCTIONS CAREFULLY, EACH TIME YOU USE
THE CHARGING EQUIPMENT.
9Follow these instructions and those published by the battery and vehicle manufacturers, and the maker of any equipment you intend to
use in the vicinity of the battery. Remember to review warning marks on all products and on engines.
8DO NOT smoke or allow a spark or flame in the vicinity of battery or engine.
9Wear safety eye protection and protective clothing. Avoid touching eyes while working near battery.
9Remove personal metallic items such as rings, bracelets, necklaces and watches. A lead-acid battery can produce a short-circuit current
which is high enough to weld a ring or the like to metal, which would cause severe burns.
9Have fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
9Wash immediately with soap and water if battery acid contacts skin or clothing. If acid enters eye, flush eye immediately with cool, clean
running water for at least 15 minutes and seek immediate medical attention.
2. INTRODUCTION
DC to DC battery charger ideal for charging an auxiliary battery in vehicles such as camper vans and caravans. Will charge your second
battery whilst driving and will be linked to the ignition switch to avoid draining your main battery. Suitable for 12V Gel, AGM, Calcium and
conventional Lead Acid batteries. Can be used in conjunction with a solar panel when the vehicle is switched o󰀨. Protected against short
circuits, open circuits, output reverse polarity, over charging, over current and overheating. Rated at IP65 water resistance. 2-Year guarantee.

4. INSTALLATION
NOTE: For optimum performance, the battery charger should be located as close to the main cranking battery as practicable. If a position
is chosen that is away from the main battery you must adhere to a cable size of 6 AWG (13.3mm2 / Ø4.11mm) for the +12V Start
battery wire (BLUE wire), +12V Auxiliary battery wire (RED wire) and common Ground wires (BLACK wires) exiting the rear of the
charger (g.2).
DO NOT use cable sizes smaller than 6 AWG when joining to these xed cables.
NOTE: Maximum recommended length of 6 AWG +12V Start battery wire (BLUE wire) is 4 metres.
NOTE: Maximum recommended length of 6 AWG +12V Auxiliary battery wire (RED wire) is 7 metres.
NOTE: Reducing cable sizes or exceeding maximum recommended lengths may lead to excessive voltage drop, causing poor charger
performance or failure signied by either the charger’s lights ashing or failure to initialise.
4.1. Secure the charger using the screws provided. See note above ref. location.
4.2. When the unit is in position connect the red, vehicle ignition power wire (g.2) to the ignition power supply. The charger will
therefore only function while the ignition system is on.
4.3. When charger is connected and powered On, the Power light will illuminate (g.1). When the charger is charging the auxiliary
battery, the green CHARGING light will be lit (g.1) and when fully charged the yellow FULLY CHARGED light (g.1) will be lit.
4.4. The thinner black wire (g.2) should now be connected. The nature of the connection depends on the type of battery being used.
4.4.1. GEL battery: Connect the wire to the common ground cable (g.2).
4.4.2. AGM / Lead Acid: DO NOT connect this wire to anything. Fully insulate the wire’s bare end.
4.4.3. Calcium: Connect the wire to the blue (+12V cranking battery) wire (g.2)
4.5. Measure and cut cable to suit distances from charger to cranking and auxiliary batteries (see g.2). Terminate the cable ends with
suitable cable lugs. Soldering these is strongly recommended to maximise connectivity.
WARNING!: An essential safety feature is to t a suitable in-line fuse or circuit breaker (not supplied) at a suitable point along the
cable between the charger and the main cranking battery.
5. MAINTENANCE
5.1. Cleaning and user maintenance should be carried out by competent persons.
5.2. Use a dry cloth to wipe all battery corrosion and other dirt or oil from the battery connectors, cords, and the charger case.
5.3. Ensure that all of the charger components are in place and in good working condition.
5.4. Servicing does not require opening the unit, as there are no serviceable parts.
5.5. All other servicing should be performed by qualied service personnel.
5.6. If any component is damaged, do not use until repaired or replaced.
