Before operating, please read it very carefully. The PCS should be operated in strict accordance with the description in the manual, in case that it causes damage or loss to equipment, personnel and property. This manual should be kept carefully for maintenance and reparation. Operator Requirements The operators should get a professional qualification, or trained. The operators should be familiar with the whole storage system, including compositions and working principles of the system. The operators should be familiar with the Product Instruction. While carrying out maintenance work it has to be at least two operators in the filed all the time. They can not operate on any equipment until they are all powered off and fully discharged. It is strictly prohibited for any maintenance to be carried out when equipments are on or charged. Protection of Warning Sign The warning sign contains important information for the system to operate safely and it is strictly prohibited to torn or damage the sign. Ensure that the warning sign is always clear. The signs should be replaced immediately if damaged. Setting of Warning Sign for Safety While instructing, maintaining and repairing, to prevent unrelated personnel nearby to cause incorrect operation or accident, the suggestions below should be followed: Obvious signs should be set at front switch and rear-level switch in case of accidents caused by false switching. Warning signs or tapes should be set near the operation areas. Keys of the system must be pulled out after maintenance or operation. Live Line Measurement High voltage in the container which may cause vital electric shock when touched by accident. ______________________________________________________________________ Alpha ESS Co., Ltd. Page 7 of 58 Your Smart Energy Safety Instructions Equipment protection must be taken in live line measurements (e.g.: insulation gloves). The measuring equipment should be connected and used correctly to ensure personnel safety. When measuring, at least two workers are needed. Measuring Equipment To ensure the electrical parameters to match requirements, related measuring equipment are required when the system is being connected or tested. Ensure that the connection and use matches specification in case of electric arc or shock. Electrostatic Prevention Contact or improper operation of the printed circuit board or other ESD sensitive components may result in damage to the device. Unnecessary contact should be avoided. Moisture Prevention It is very likely that moisture may cause damages to the system. Do not open the container door if the humidity is larger than 95%. Repair or maintaining activities in wet conditions should be avoided or limited. Operation After Power Failure The battery system belongs to energy storage system, which maintains fatal high voltage even when the DC side is disconnected. Therefore, touching of the battery output is strictly prohibited. The PCS maintains fatal voltage even when both the DC or AC side are disconnected, so it must be tested by the multimeter for safety before operation. Minimum Personal Protective Equipment For the safety of operators to the system, personal protective equipments are required. During the operation, following protective equipments are required: No. Item 1 Work clothes 2 Protective shoes 3 Protective glasses Notes When doing maintenance works such as checking cables or wires, measuring voltage, replacing small electrical parts or cleaning modules and brackets, as minimum the following protective equipments are required: ______________________________________________________________________ Alpha ESS Co., Ltd.

Notes After all of the equipments are out of operation, the following notes should be paid attention to while maintaining: Related safety standards and specifications should be followed in operation and maintenance. Disconnect all the electrical connections so that the equipment would not be powered on. Wait at least 15 minutes after disconnection in case that the residual voltage of capacitors down to safe voltage. Use a multimeter to ensure the equipment is completely uncharged. The amount of maintenance staff should be not less than two while maintaining. The equipment should be repaired by professional staff and it is strictly forbidden for maintenance staff to open equipments on their own. Appropriate protective measures should be taken while maintaining, such as insulated gloves, shoes, and anti-noise ear plugs. Usually the location of the storage system is far away from urban areas. Related emergency rescue measures should be prepared in order to be implemented when necessary. Life is priceless. Make sure no one would get hurt first. When a fire happened in the container, just make sure the fire system is on (should be on), then leave the container as soon as possible. After running out, make sure all doors are closed. The fire extinguishing system would automatically work. Do not try to put the fire out manually. When a fire happened in the PCS container, just close the door and press the emergency button manually. When the fire is outside the containers, please make sure all doors are closed in case of smoke. Smoke may cause warnings of sensor, but it will not trigger fire system. If the fire spreads into the container, the temperature sensor would work and the whole system would ______________________________________________________________________ Alpha ESS Co., Ltd. Page 53 of 58 Your Smart Energy Routine Maintenance start. For single cell, it is better to be sank into water to block burning. The batteries need to be charged to 30%~50%SOC rate when the whole system is static (that is, the batteries has not been charged for two weeks or longer) for a long time, in case of over discharge.

Page 55 of 58 Your Smart Energy Troubleshooting Emergency Handling Plan In order to prevent accidents such as electric shock, fire or explosion, the emergency switch should be pressed immediately to stop the equipments when abnormal sound, smell or sparks is found. Disconnect the AC breaker. Check the control power supply. If it is OK, return the power supply to find out the reason. Please record every detail related to the fault, so we can analyze and solve the fault better. Any operation of equipments is strictly forbidden, please contact us as soon as possible. When the batteries are on fire, do not try to put the fire out manually. That is dangerous because the special chemical property of lithium-ion batteries (though LiFePO4 is safer, there is possibility of danger). Water or other liquid is not recommended. Novec 1230, FM-200, or dioxide extinguisher are recommended. ABC extinguishers are not effective when the battery pack is on fire. As battery cell contains little Oxygen inside and all cells have got explosion-proof valve, explosion hardly happens.
