4.10 Installation of the Battery Module to the Rack Insufficient or no grounding may cause an electric shock. Device malfunctions, and insufficient or no grounding may cause device damage and life-threatening electric shocks. Note: Before installing the battery, please turn the manual switch of the high-voltage control box to the off position.
For the correct installation method shown in the first picture, stack battery packs from bottom to top, and place the high pressure box on the top of the cluster rack. Insert the slide of the cabinet at the top of the rack into the high-voltage control box. After the battery module and control box is inserted into the rack, use M6*20 hex socket combination screws to fix all the lugs of the battery module and control box on the side beam in turn.
4.10.2 Battery installation cable Description For details on how to connect all cables, see Section 4.8. When connecting cables, observe the installation diagram and pay attention to the direction of the communication cables. Otherwise, the products may not work properly due to incorrect cable installation.
After the battery module is placed in the control box, take out a 200 mm communication cable to connect the communication port of the battery module and the high-voltage control box, and 11x160mm communication cables to connect the battery module communication port (IN-OUT) from top to bottom.

7. Maintenance and upgrade Warning! Improper decommissioning may cause damage to the equipment and/or battery inverter. Before maintenance, ensure that BOS-A is decommissioned according to relevant provisions. Note: All maintenance work shall comply with local applicable regulations and standards. The USB disk port of BOS-A has the functions of upgrading firmware and recording battery data, which can be used as an auxiliary tool.
7.2 USB’s Upgrade Step USB type: USB2.0, FAT32. Create the upgrade folder according to the directory. Place the upgrade file provided by the supplier in the upgrade folder. Turn on the battery, and insert the USB flash disk after the blue indicator is on. After the blue light indicator flashes and turns off, pull out the USB flash disk to complete the upgrade.
8. Battery Module Storage To ensure the battery service life, the storage temperature shall be kept between 0°C~35°C. The battery shall be cycled at least once every 6 months. To minimize self-discharge in a long storage period, disconnect the battery connection (1/2) of the high-voltage control box of the DC connecting cable.
9. Disposal For details related to the disposal of battery modules, please contact us. Service Hotline: +86 0574 8612 0560, Email: service-ess@deye.com.cn.
