Positive output power cable (1500mm) Negative output power cable (1500mm) RS485 communication cable (1500mm) Warning 1. For operational safety and compliance, please disconnect the communication and cable link with the inverter when storing the battery. 2. During the handling and installation of the battery, it is recommended to wear safety helmets, goggles, 15 protective shoes and other safety equipment suitable for the work to prevent accidental injury; 3. All wiring must be carried out by professionals. With the right cables, the battery connection is essential for the safe and efficient operation of the system. In order to reduce the risk, please use the cable provided by our company, or our recommended cable specifications. 4.3 Charging operation 1. Check before charging. Inspect the appearance of the battery and inverter or other connected equipment to ensure that the power cord and all wiring harnesses are connected. Make sure the power supply meets the specification requirements for the battery. 2. Turn off the inverter or other equipment, connect the positive and negative terminals of the battery, and connect the communication cable normally. Warning: Before connecting the battery, ensure that the positive and negative terminals are connected. Do not reverse connect. 3. Connect the charger to the power supply and turn on the charger. 4. Start the battery, the POWER indicator is on, and the SOC indicator flashes to start charging normally. Standard Charging: First, charge the battery to 57.6V with a constant current of 20A (0.2C), and then charge to 5A (0.05C) with a constant voltage of 57.6V. Note: All tests stated in this document shall be performed at 25±2. 4.4 Discharge operation 1. Before discharging, check whether the load and equipment are turned off. 2.
