- CAUTION — To reduce risk of injury,damage,even burst. please use ii following using manual. In case of causing personal
- Do not disassemble the battery. Take it to a qualified service center when service or repair is required. Incorrect re-assembly may result in a risk of fire.
- To reduce risk of electric shock, disconnect all wirings before attempting any maintenance or cleaning. Turning off the unit will not reduce this risk.
- CAUTION – Only qualified personnel can install this device with inverter.
- For optimum operation of this battery, please follow required spec to select appropriate cable size.
- Be very cautious when working with metal tools on or around batteries. A potential risk exists to drop a tool to spark or short circuit batteries or other electrical parts and could cause an explosion or fire.
- Please strictly follow installation procedure.
- To support full output load, at least 2 sets of FLA48V for inverter larger than 6KVA in parallel connection.
- GROUNDING INSTRUCTIONS – This System should be connected to a permanent grounded wiring system. Be sure to comply with local requirements.
- NEVER cause AC output and DC input short circuited. Do not connect to the mains when DC input short circuits.
- Warning!! Only qualified service persons are able to service this device.
- Battery should be installed indoor and kept away from water, high temperature mechanical force and flames.
- Do not install the battery in any environment of temperature below 0°C orover55°C,and humidity over BO%.
- Do not put any heavy objects on the battery.
Can be connected in parallel
- The batteries can be connected in parallel. Series connection is not allowed. Use in upright position only.
- The batteries are not allowed to connected with PWM controller for charging.
Special Attention : Due to the built-in protection board of the lithium battery pack is with over-discharge protection function, it is strongly recommended to stop using the load when the battery pack is over-discharged. The battery pack cannot be repeatedly activated for discharge. Or the battery may be failed to be activated by the AC or PV activation cable ( It requires a special charging activation method), so cannot be charged. Therefore, when the battery pack is low power, please charge the battery as soon as possible when main power or solar energy is available.
