ECO-WORTHY ECO-DCDC1240 DC to DC Battery Charger

WARNING!

• To avoid any personal injury, please read the safety instructions below.
• This battery charger is not intended for use by children or infirm persons without supervision.
• FOR AUTOMOTIVE AND RECREATIONAL VEHICLE 12V DEEP CYCLE BATTERY USE ONIY.
• NOT TO BE USED WITH DRY CELL BATTERIES.
• During the charging process, do not use a naked flame near a battery. Batteries generate explosive gasses during the charging process that may explode.
• Never smoke or light cigarettes near a battery.
• Do not place tools on top of a battery or allow tools to fall on the battery to prevent the chance of a short circuit and sparks.
• Always wear eye protection when charging a battery.
• Ensure charging and testing are conducted in a well-ventilated area.
• Inadequate ventilation may overheat the charger and cause in-efficient 叩eration.
• This battery charger is not intended for outdoor operation. Do not expose it to moisture or extreme weather conditions.
• The ACID/FLUID within a battery is highly corrosive and poisonous. It can produce flammable and toxic gases when recharged and will explode if ignited. When working with batteries, always wear eye protection, remove jewelry and ensure the area is well-ventilated. If spilled – it will cause severe burning to eyes, skin, and clothing, damage paintwork, and corrode many metals. Ensure that power is disconnected from any appliance in the vicinity of the spill and imme-diately wash any area that has been affected with water.
• The warnings, cautions, and instructions detailed in this instruction manual cannot cover all possible conditions and situations that may occur. Common sense and caution are factors that cannot be built into this product and must be supplied by the operator.

Installation Options/Instructions

Installing the Charger

• Installation of this unit will require twin core wiring – and suitable cable connectors (not included). See the specifications page for details.
• Any existing cables used in conjunction with this charger will require checking to ensure size is suitable gauge. Where necessary replace with suitable gauge wiring if they do not meet minimum specifications.
• Locate where you are going to install the DC-DC charger. Ensure the charger is located in a suitable dry area in the vehicle or caravan.
• Ensure the charger is securely mounted using the brackets and screws provided. The charger can be mounted overhead, vertically, or horizontally.
• Next, measure the required cable length from the main vehicle battery through to the location of the DC-DC charger.
• Ensure ALL cabling meets specifications and will not be exposed to excessive heat/moving parts or abrasion.
• If the charger is located in a camper/caravan we recommend the use of an Anderson-style plug between the tow vehicle and the camper/caravan as shown below.
• Fit suitable connectors on either end of the twin core cables.
• Connect the auxiliary battery to(-) shared negative and (+) charger output using twin core wiring as per recommended cable size.
• Using the twin core wiring laid between the main starting battery and the DC-DC charger, connect the red (+) to the (+) DC input terminal and the black (-) to the (-) shared negative on the rear of the charger. Finally, make the power connections to the main starting battery of the vehicle. It is recommended to install a 50Amp circuit breaker (not included) as shown on main diagram. The circuit breaker should be located close to the starting battery.
• Check all connections are tight.

DC-DC Charger Installation

• This DC-DC charger has two modes: DC input and solar input. You can select DC input mode or solar input mode first when installing.
• Select the battery type to be charged on the charger panel.
• Connect the auxiliary battery to the output port of the DC-DC charger

DC-DC Charger Removal

• If you need to remove the charger or battery, please remove the negative pole of the auxiliary battery first, and then remove the double room.
• Remove the DC input port or solar input port of the charger. Both input ports can be removed first.

Operating The Charger

CHARGER DISPLAY

1. DC Battery
   • Once correctly installed, the DC-DC charger is a simple set and forget dual battery switch.
   • Start the vehicle and let it idle.
   • The charger will now recognise that there is charge being applied to the main starting battery.
   • Once the main starting battery has reached is.ovolts the charger will begin to charge the auxiliary battery.
   • The initial default setting is for AGM/Gel batteries.
   • If you are charging a battery with a different chemistry simply change the battery type by pressing the battery type selector button on the front panel of the charger.
   • Once selected, the charger will remain on this battery type until it is changed.
   • The charger will continue to operate even after the vehicle has been switched off, however once the main starting battery falls belowis.o volts the charger will automatically shutoff.
2. Solar Input
   • Once correctly installed, the DC-DC charger is a simple set and forget dual battery switch.
   • Once connect the input terminal with solar panels positive and nega-tive, the charger will transfer to solar charge mode.
   • If you are charging a battery with a different chemistry simply change the battery type by pressing the battery type selector button on the front panel of the charger.
   • Solar charging requires an input of 16 to 25 volts from solar panels. When available solar panel voltage falls below 16 volts no charge will be delivered to auxiliary battery.

WARNING!

• Failure to use recommended wiring will severely impact on the performance of the DC to DC charger.
• When the positive and negative poles of the charger are reversely connected to the positive and negative poles of the battery, the charger will beep
• When the charger is fully charged for the auxiliary battery, the voltage drops too fast, the system will judge it as a bad battery, and the charger will beep
• When the charger is charging the auxiliary battery, the auxiliary battery will be fully charged quickly, then the system will determine that the battery is a bad battery, and the charger will beep

Additional Information

• It is expected that this charger will be used to charge a ‘deep cycle’ type auxiliary battery. Deep cycle batteries are designed to provide battery power to run items like fridges and lighting in caravans and campers.
• An ordinary compressor refrigerator consumes 5 amps, so it uses about 120 amps in 24 hours. Therefore, if the 100Ah battery only runs in the refrigerator (and there will be no other output), ideally, the battery needs to be charged after 20 hours.
• To replenish these 80 amp hours using a 40 amp DC- DCcharger will require at least 2.5 hours of driving. A twenty-amp unit will require at least 1 hour of driving to fully recharge the battery.
• The readings are taken at room temperature of 26 °C (78 °F); the battery rested for 24 hours after charge or discharge.
• Voltage readings & specific gravity of electrolyte (lead acid batteries) can give an indication of your battery’s state of charge.

Fault Finding

• The charger won’t indicate » charging.
• The charger is not connected to the battery.
• Check the terminal connection.
• The battery is not 12V.
• The battery won’t charge. »
• Verify that all wiring meets specifications.
• Check the condition of the batteries.
• Check the performance of the alternator.
• The battery won’t fully charge or hold charge.
• Batteries that are over 3 years old; severely discharged (or previously been severely discharged); not regularly recharged; over-heated; low in the electrolyte; undercharged; overcharged or sulfated may not accept or hold a charge. A good automotive store or battery outlet often offers a free or low-cost in-store service to check the condition of the battery. Your battery may require replacement.
