From the perspective of electromagnetic radiation, all these devices should meet the national standards for electromagnetic compatibility, and strictly speaking, they should not pose any harm to the human body.
But three-phase UPS power exceeding 10kVA is defined as equipment used in restricted areas, which means it should be installed in a separate electrical room rather than in a computer room. But this is only considered based on the safety of its power supply, without considering it from a human perspective. But the electromagnetic compatibility requirements for these two types of UPS are completely different. In this sense, it is also possible to cause harm to individuals.
Working in such a room for a long time can still cause some other harm to the human body:
Noise: The noise from air conditioning and UPS is very loud, which can cause irreversible hearing loss;
The air-conditioned room has a constant temperature and humidity, while the outside changes throughout the year, which may cause diseases such as rheumatism.
Working intermittently in these rooms in the short term should not pose any major problems. But to work in such a room for a long time, some preventive measures are needed. The best preventive measure is to separate the work area from the equipment. This is necessary for computer room design.
