The installation and maintenance of the battery cabinet must be operated by professional and technical personnel, and the use must strictly comply with the relevant safety regulations. Non-professionals are strictly prohibited from installing and maintaining battery cabinets as well as over-range abuse. Note: COSLINK will not be responsible for any damage to the battery or other losses caused by not using the battery in accordance with the specified requirements or using it beyond the specified scope. Connection of Battery Cabinet Since the battery cabinet works in a high-voltage and high-current environment (up to 900V), the safe and reliable wiring connections need to meet the following basic requirements. (1) Connection cable to meet the 1000V DC voltage, instantaneous current 300A, continuous current 150A use requirements. (2) Each connection must be safe and reliable, to ensure that there will be no loose, false contact problems, contact resistance close to 0, the connector must have corrosion resistance, wear resistance, anti-vibration function. (3) Various connections must meet the requirements of the relevant national standards, to prevent various forms of arc discharge. (4) The connection between internal batteries must have anti-vibration and anti-loosening devices, temperature, voltage and current sensor connections also need to be safe and reliable to prevent loosening, aging and extrusion.It is strictly forbidden to have any exposed metal in each induction line. (5) Strictly prevent any form of short circuit in the process of connection. (6) operators are strictly prohibited from unarmed operation without protective equipment. (7) All connections must be made under clear guidance, and any form of guesswork and vague attempts to work in this manner are strictly prohibited. (8) The key points of the connection : to ensure that the connection is correct, reliable (will not come loose), good contact (no contact resistance or very little contact resistance), and no short circuit. (9) After the connection is completed, it must be measured and confirmed point by point. (10) All connection points must ensure that no contact with the outer box or other components, short circuit. (11) If there are other uncertainties, professionals must be consulted to confirm before implementation.Customized Commercial Industrial ESS website:http://www.coslinkess.com/user-ess/commercial-industrial-ess/
