Note: EN31260 and EN32430 have the same dimensions. Page 16 Enerdrive ePOWER Battery Charger Owner’s Manual (Rev. 5.
Chassis Grounding Connection DANGER THIS CHARGER REQUIRES CORRECT GROUNDING. The unit chassis has to be grounded properly. Never operate the Charger without proper grounding. Failure to do so may result in poor charger performance, serious injury or possible death. Connect the unit’s chassis ground to the common ground point through the ground stud located near one of the unit mounting slots. See image in Section 3, page 10.
• 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.
standard RJ12 cable (maximum length 7.5 meters) is required. • Install the standard RJ12 cable in your desired location. • Connect one end of the RJ12 cable to the Interface Port and the other end of the cable to the Display Panel.

5. UNIT OPERATION Understanding The Charging Mechanism • The ePOWER 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 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 until it reaches float stage.
absorption-to-float mode current settings. For Charging Lithium 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.
Understanding The Function Key ‘MENU’, ‘SET’ And ‘SEL’ During Charger Setting 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. Note: The selected setting will quickly flash 3 times to acknowledge the setting.
anyone of the battery bank is discharged to lower than 12.8V or after seven days in float stage to refresh the battery banks. 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.

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 cycle.
Use the following procedure to setup the charger for battery equalisation. 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.
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. E01 Unit shutdown due to low AC Input (< 85 +/- 5Vac) Check AC input source.
