DCS system maintenance, data center conditions

• The power supply I/A system requires a power source that is continuous and stable, as well as the capability to provide power from batteries for a certain period of time in order to cope with unexpected events on the mains supply line. It is recommended to use an uninterruptible power supply UPS with isolation. The capacity of the UPS depends on the scale of the I/A system; generally, 1.5KVA is allocated for each cabinet along with an operation console. The battery supply time is required to be maintained at 15–30 minutes. • Grounding: An independent grounding electrode must be provided for the I/A system, with a grounding resistance of less than 5 ohms (1 ohm for power plants). The safety ground of the I/A system, the AC power supply ground, and the logic ground of internal signals should all be connected to this ground terminal. The grounding of any device that is not of type I/A must not be connected to this ground rod. • Temperature: The temperature in the control room must be kept between 15 and 30°C. To calculate the air-conditioning capacity, the heat dissipation values for each device in the I/A system are provided in detail in the manual. Please refer to the Site Planning section in the B0193AA manual. • Humidity: The humidity in the control room must be maintained between 20% and 80%. • Air particles: It is necessary to control the dust in the control room to prevent dust from entering. Please establish daily rules and regulations for the control room to ensure the proper operation of the I/A systems. Additionally, establish the necessary rules and regulations for the server room, specify the facilities required to meet the aforementioned conditions in the server room, and assign dedicated personnel responsible for their maintenance.
