1. Look at the material, you should choose a sheet metal chassis cabinet, and the steel plate must be thick, you can feel which ones are thick and which ones are thin when you knock them with your fingers. Its rugged enclosure protects the board, power supply and storage devices, and is resistant to voltage, shock, and dust.

1. Power failure: The power supply of the fan fails, such as the power cord is disconnected, the power plug is loose, etc., which will cause the current to fail to transmit normally, resulting in the fan stopping and rotating. 2. The temperature is too low: Some heat dissipation windbreakers have a temperature protection function, when the temperature is too low, the fan will automatically ...

"In 2022, with all the challenges, especially for small and medium-sized manufacturing companies – we need to think differently: if we want to support our customers and add value in our digital transformation, it's not just a single product innovation that will change. It will combine automation, digital ...

If the indoor temperature is higher than the outdoor one, or the indoor temperature is higher than the set temperature, the air conditioner will not start; Solution: Test the temperature comparison between indoor and outdoor to check whether the indoor temperature is too high. The voltage of the air conditioner is unstable, and the compressor cannot be started normally.

1. The host, storage equipment, and server cabinets should be partitioned and arranged, and the host, storage equipment, server cabinets, UPS power supplies, precision air conditioners and other equipment should be set aside for maintenance according to product requirements, and the maintenance interval overlaps with adjacent equipment; 2. Enter the equipment in the computer room in stages.

Indoor unit: suitable for all kinds of control boxes, distribution boxes and electrical cabinets in machinery, electric power, chemical industry, textile machinery, automation equipment, instrumentation and other industries with high requirements for temperature and humidity.
