1. Safety Precautions
This section describes the safety information that must be observed when working with battery packs. To prevent any damages, or personal injury, and to ensure the performance of the battery packs, please read this section carefully and observe the safety precautions at all times. 1.1 Precautions It is very important and necessary to read the user manual carefully before installing or using
the product. Failure to do so or to follow any of the instructions or warnings in this document can result in electrical shock, serious injury or death, and could damage the battery, or potentially rendering it inoperable. If the battery pack is stored for long time, it is required to charge them every six months, and the SOC should be no less than 50%. Please recharged the battery pack within 12 hours, after fully discharged. All the battery pack terminals must be disconnected before any maintenance. Do not use cleaning solvents to clean battery pack. Do not expose battery pack to flammable or harsh chemicals, or corrosive gases or liquids. Do not paint any part of battery pack, include any internal or external components. Do not expose the battery pack to direct sunlight for extended periods of time. Do not connect battery pack with PV solar wiring directly. Do not insert any foreign object into any part of the battery pack. 1.2 Warning
Do not touch the battery pack with wet hands. Do not crush, drop or puncture the battery pack.

SEPLOS PUSUNG-135 51.2V 135Ah
PUSUNG series is a professional storage battery pack solution designed and produced by SEPLOS. PUSUNG-135 is designed to fit SEPLOS 3.2V 135Ah prismatic cells with high safety ratings and better performances.
2.1 Features Suitable for SEPLOS 3.2V 135Ah LiFePO4 prismatic cells. Battery cell is made from lithium iron phosphate (LiFePO4) with safety performance and longer
cycle life. Performance update: laser welding to improve performance Safety update: Add a trip breaker to offer double protections. If the the BMS MOSFET
malfunctions, BMS will send control signals to the trip breaker, and the circuit will be cut off in case any unexpected conditions. BMS has over-discharge, over-charge, over-current, high and low temperature warning and protection functions. BMS monitors the charge and discharge state, and balance the current and voltage of each cell.

RESET Reset button: to start the battery pack, hold the button for 2s to turn on battery pack. RS485 RS485 communication interface: RJ45 port, follow RS485 protocol. For transmitting battery pack information between paralleled packs. The first 4 DIP switches (#1, #2, #3, #4) are used for identifying packs’ information on software. CAN CAN 5 communication interface: follow CAN BUS protocol, for output pack information to inverter. One pack should be assigned as master pack. And the last 4 DIP switches (#5, #6, #7, #8) to tell how many slave packs are followed. The firs DIP switches are used for identifying slave packs. ADS ADS Switch: To setup battery address for identification, and make the communicate between batteries, battery to inverter.
NOTE: There are 8 bit DIP switches, keep the switch on down side means `OFF’, turn up the switch to top side means `ON’.
