Precautions For Use
1) There is high voltage inside the energy storage system. It is strictly forbidden to open the case for disassembly, assembly and maintenance without the company or its authorized technicians, otherwise the electric shock will be released and the warranty rights will be lost.
2) It is strictly prohibited for any wire or connector in the BMS to overlap the positive and negative poles of the battery, otherwise there may be a danger of short circuit and damage the circuit board.
3) it is strictly prohibited to be close to the water source or fire source to avoid the fire of the battery due to short circuit or overheating.
4)after the secondary protection is triggered, the circuit breaker is controlled by BMS. After disconnection, the system must be powered off to eliminate the fault, and can be powered on and started again after an interval of at least 1 minute, otherwise it may cause damage to the shunt coil of the circuit breaker because it is too late to emit heat.
5) If you need to cold start the UPS/PCS from the battery, you must first close the battery switch on the UPS/PCS side before starting the battery. If you start the battery first, and then close the battery switch on the UPS/PCS side, since the DC side of the UPS/PCS side generally has a large capacitance, the instantaneous capacitance is equivalent to a short circuit. At this time, the current charged by the battery to the capacitor will be much higher than that of the RBMS machine. The rated value of the contactor is very easy to cause ablation and adhesion of the contactor's contact. The contact resistance of the contactor's contact increases and heats up or the contact cannot be disconnected, which triggers the secondary protection
