Multistage Charging Process for Lead Acid Batteries The Battery Charger is a fully automatic, set and forget charger. It is designed to quickly and accurately recharge your deep cycle batteries utilising charger algorithms that help to maximise the life of your specialised deep cycle batteries. These Battery Chargers feature multistage smart charging technology that enables the charger to be connected to your battery banks permanently.
Smart Charging Feature The Battery Charger will regulate its output based on the loads connected to your battery banks. This function is important to maintain the life of your battery banks as some battery chargers mistake loads for discharge and continue to keep the batteries in the bulk or absorption stage for extended periods of time, which will damage the battery bank. The Battery Charger has two methods of load based regulation to ensure your battery charger transitions to float when it should do so.
EN312100 Note: Actual voltages dependent on chosen algorithm. In the event of AC mains loss the charger will react according to time without mains power. Loss of AC power for less than 4 min - Charge resumes at existing stage. Loss of AC power for more than 4 min - Charge resumes at bulk stage. See page 29 for Lithium settings.

4. INSTALLING THE CHARGER WARNING Enerdrive recommends that all wiring be done by a skilled technician to ensure adherence to the best practice standards for on-board DC electrical installations. Failure to follow these instructions can damage the unit and could also result in personal injury or loss of life.
Mounting The Charger • Choose an appropriate mounting location. • For installing in an indoor location, the unit can be mounted in any direction although mounting the charger vertically provides the best thermal performance. • For installing in boat or marine environment, the unit can be mounted horizontally and vertically (AC and DC panel facing downwards only) to provide adequate drip protection. • Use the base of the charger as a mounting template to mark the positions of the fixing screws.
Chassis Grounding Connection The unit is grounded through the ground stud located near the DC Output terminals, refer Section 3 on Page 10 and 11. • For caravan, RV and other mobile applications the unit should be grounded with a minimum 4mm2 conductor. • For marine applications the unit shall be grounded to the main DC negative bus with a separate conductor the same capacity (size) as the DC positive conductor.
• Remove the DC compartment cover by removing the two screws located on the top surface of the unit near the AC wiring compartment. • Keep the connection between the battery and the charger as short as possible. • Connect one end of the positive wire (red wire) to the Bank one of charger positive terminal with torque 4.0 ~ 5.0 N-m and the other end to the over current protection device, then the DC disconnect device. Do not over tighten as this may result in damage to the charger.
Running The Battery Charger With Portable Generators This charger is suitable for use with most sine wave inverter type generators only. Ensure your generator never runs out of fuel when running the battery charger. When a generator runs out of fuel, its final splutters of life produce very transient AC voltages that can damage your battery charger. Be sure to purchase a good generator that has a clean AC output.
Battery Wiring: Connecting The Batteries The Right Way EN31220, EN31240, EN31260, EN32430 (Picture shows 12V setup - 24V would connect the same way but with 24V banks). Positive Negative IMPORTANT NOTE For Single Bank Charging: DO NOT Connect Bank 2 And 3 Outlet. Page 22 Enerdrive Battery Charger Owners Manual Rev. 5.

5. UNIT OPERATION Understanding The Charging Mechanism • The battery charger is a three bank battery charger that is capable of charging a maximum of three battery banks. • The charger is designed to have Bank 1 charge the main battery bank. Always use Bank 1 first when connected to a single battery bank. • At the start, if the charger senses Bank 2 and 3 has battery voltage above 12V, the charger will then concentrate on fully charging Bank 1 first or until it reaches float stage.
For Charging Lithium LiFeP04 Batteries This can only be set at Bank 1, it has its own charging voltage and current setting. It also requires the user to set the charger termination current. The charging process will terminate when the charging current drops to the set termination current. Bulk re-start occures when battery voltage drops below 13.3V DC. 1 EN312100 can be programmed for Lithium on 2 & 3.
Understanding The Function Key ‘MENU’, ‘SET’ And ‘SEL’ During Charger Setting With the AC connected and turned ON: MENU: Press and hold the key for longer than 3 seconds to enter charger setting mode and show function setting. Once new setting is done, press ‘MENU’ again for longer than 3 seconds to exit the charger setting mode. SET: Press the key once to keep / save the chosen setting and change the display to show the next menu to continue other settings.
Understanding The Battery Temperature Functions The Battery Temperature Sensor is included with the charger to protect your battery and provide better charging voltage accuracy. When the battery temperature sensor is used, it is highly recommended to be installed on the main battery bank at the negative terminal - Bank one. The sensor senses the battery temperature and overrides the manual temperature settings and makes small adjustments to the charging voltage.

CAUTION RISK OF BATTERY AND EQUIPMENT DAMAGE. Only the Flooded lead-acid can be equalised. Consult your battery manufacturer or read the battery manual when you try to equalise your batteries. Disconnect any DC load connected to the battery, as during equalise mode, the charger will produce 15.5V to the batteries. You must monitor the battery specific gravity throughout the equalisation process to determine the end of the equalising schedule.
Understanding The Silent Mode Function The charger also comes with a unique function called Silent Mode, which will stop the internal fan from operating. TIP: Use this function during night time or when a quiet environment is needed. Please also note that the charging time will increase in this mode because the charger is not running at maximum power. This function can switch to ON or OFF at any time during the charging period. function can switch to ON or OFF at any time during the charging period.
Understanding The Protection Features De-rating Charging Current: When the charger senses the environmental temperature is above 50°C, the maximum charger current will de-rate to 1/2 of the value (A02 warning code will display). The charger will recover automatically back to maximum charging current when the environmental temperature drops to below 45°C. Over Temperature Shutdown: When the charger senses the environmental temperature is above 60°C, the charger will shutdown.
Understanding The Error Codes Error codes will show on the display when either an internal fault such as high internal temperature or external fault like AC input voltage out of range is detected. The unit will shutdown. Code Condition Corrective Action A01 Temperature Sensor (BTS) is defective. Check and or replace the sensor.
