Part 2 System Installation and Maintenance 1. It is recommended to install in the following locations я Close to the battery room. я Close to public power outlets. я Close to important loads that require power supply. я Keep away from heat sources. я Place in a clean, ventilated and easily accessible place. я There is a certain gap around the equipment. 2. Inspection before operation я After the new equipment is in place, check whether the fasteners are loose, whether the components are intact, and whether the thread ends are loose. я The equipment should be reliably grounded and check whether all wiring is correct.

я Check whether the battery connection piece is correct and the polarity is consistent. я Check whether the wiring between the module and the central monitor is secure. 3. Normal operation я Make sure it is correct, and put all switches in the off state before powering on for trial use. я When the AC switch (1ZK and 2ZK) is closed and there is AC power supply, the rectifier converts the AC power into DC power and rectifies and filters it. Then charge the battery with constant voltage and current limit. At the same time, it also supplies power to the control bus load. я All charging module indicators are normal and the charging system outputs normally.

After charging starts, all voltmeters and ammeters have a certain numerical value. 4. Before connecting the DC power supply to the main power supply and working load, the following measures should be taken я Always remember that the DC power supply is a power generating device, so the user must take all necessary measures to avoid direct or indirect touch. я Check whether the specifications given on the nameplate of the DC power supply meet the installation requirements and whether they are consistent with the specifications on the order. я In the lower part of the device, you can see the input and output power cord terminals connected to the DC power supply and important loads.

я The cable cross section is selected according to the rated current, and the circuit breaker is selected according to the maximum current. The maximum current working conditions are not considered as long-term operating conditions. condition. я The DC power supply and the battery cabinet are connected through the cable trench at the bottom of the cabinet. Pay attention to the positive and negative poles of the terminal board and the color of the cable. —- 10 —-
