PACKING LIST

IDENTIFICATION OF PARTS

INSTALLATION INSTRUCTIONS

• Please check whether the specification of your cable is compatible with this DC – DC charger. This charger can be installed both horizontally and vertically.
• Please make sure that the charger is installed as close as possible to the battery you are going to charge, and you also need to make sure that the areas is not susceptible to moisture, water, dust or high temperatures.
• Please ensure that there is no heat source or flammable gas around the unit.
• Anderson plug is recommended when this charger is installed on a caravan or a campers (see picture below).
• Twin core cable will be used between the start battery and the charger,and you need to connect the common negative and common positive wires from the starter battery to the input of the DC – DC in the appropriate positive and negative terminals.
• It is highly recommended to install a 60 Amp circuit breaker ( not included in this package ) that should be installed near the starter battery.
• Check whether all connections are clean and tight.
• You can connect the optional ACC line to the ignition of your vehicle, then turn your key to the ACC position when engine starts , which will be detected by the DC – DC charger. And the main battery will start charging your auxiliary battery.
• Note: the charger may discharge your main battery if the ACC line is connected but you key is not turned to the START position

HOW TO USE

1. DC Battery
   Start your vehicle and let it idle.
   And the charger will recognize that there is a charge being applied to the main starting battery.
   The charger will charge the auxiliary battery when the main starting battery has reached 13V (ACC line not connected). The main battery will start charging the auxiliary battery when its voltage is or above 11.5V (ACC line connected).
   Press “POWER” to re-select batteries (The default setting is for lead acid battery, and your setting will be saved once selection is made).
   The charger will continue to operate even after the vehicle has been switched off, however when the main starting battery falls below 12.5V the charger will automatically shut off (ACC line not connected). When the main starting battery falls below 10.8V, the charger will automatically shut off (ACC line connected).

2. Solar Input
   The charger will shift to solar charge mode when the input terminal is connected to the solar panel.
   Press “POWER” to select the corresponding battery type, and batteries can be re-selected during charging by long pressing the button.
   Charging begins when the output of solar panel reach 16V~25V,and the panel will stop to charge when its output is below 10V.
   Note: This charger is not designed to charge your auxiliary battery with DC inputs and solar concurrently, DC enjoys input priority over solar. When the voltage drops to 13.2V for LiFePO4 battery/12.3V for AGM, Gel & Calcium after a full charge, a recharge will begin.
   Wake-up of Lithium-Ion Batteries in Sleep Mode: this DC-DC charger cannot charge a lithium-ion battery in sleep mode. To charge the lithium-ion battery, first make sure the DC-DC charger is correctly connected to the battery. Then select the “LiFePo4” mode, and long press “POWER” for 5s. The “charging” (red) indicator will flash for 10s. If the battery is successfully waken up, the “charging” (red) indicator will be constantly on and the DC-DC charger begins to charge the battery. Otherwise, the DC-DC charger will enter the standby state and the “Power On” indicator will be on.

DEEP CYCLE BATTERY MAINTENANCE

This DC-DC charger by ATEM POWER will be used to charge your auxiliary battery, for example, deep cycle batteries that are designed to provide power for your fridges and light in caravan or camper.
Your fridge might use appropriately 24AH per day. In this light, if your 100AH battery is only used to power your fridge while receiving no charge, and it would require charging after 48 hours.
To replenish the capacity of the battery (100AH capacity, 50AH discharged), you may need to use a 40amp DC-DC charger that would further require at least 1.25 hours of driving/solar charging. A 30 amp unit will require at least 1.67 hours of driving/solar charging to fully recharge the battery. A 20 amp unit will require at least 2.5 hours of driving/solar charging to fully recharge the battery.

BATTERY WIRING

This diagram is for a reference only. Local rules and regulations should be followed when installing this unit.

NOTE: First connect the ACC line to the ignition of your vehicle. Then turn your key to the ACC position when engine starts, which will be detected by the DC-DC charger. And your auxiliary battery will be charged via the main battery.

TROUBLESHOOTING

Display shows that the charger is not charging: check where the battery is connected; check the terminals; check whether the battery is 12V
