Precautions For Use:
1)There is a 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 circuits and damage to 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 a 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
Safety Precautions:
1)The tools used by installation and commissioning personnel must have insulation protection.
2)During installation, debugging and maintenance, you must wear insulated rubber gloves, goggles, and insulated rubber boots as appropriate to avoid safety accidents as much as possible.
3)If the metal of the wire ends during the installation, debugging and maintenance process falls into the battery room, be sure to use an insulated tool to take it out, and do not leave the sundries.
4)When maintenance is required, the main circuit breaker of the RBMS must be disconnected, and the connection between the battery pack and the PCS DC bus must be cut off.
5)According to different project requirements, the parameters such as the charge and discharge current and charge and discharge voltage of the battery management system have been set during the initial installation and commissioning.
The parameters must not be changed without authorization, otherwise, the battery life may be shortened, and the battery may be affected more seriously. Cause serious harm and cause safety accidents.
6)In case of fire around the energy storage cabinet, please use a dry powder fire extinguisher or fire sand to extinguish the fire. Using liquid to extinguish the fire may cause electric shock.
7)If the system is not used for a long time, be sure to disconnect the main circuit breaker of the battery cabinet.
8)Try to avoid long-term use in the following working environment:
◎Places that exceed the temperature or humidity range specified in the specification
◎Places subject to strong vibration or susceptible to impact
◎Places exposed to direct sunlight or close to heat sources
◎Places with dust, strong corrosive substances, flammable and explosive materials, and high salt spray
