UPS power supply is widely used in shopping malls, supermarkets, banks and other enterprises and institutions. The main function of this power supply is to provide continuous power supply to the unit in the event of a power outage, thereby ensuring the normal operation of computer network systems and other application systems, effectively avoiding data loss. How to install and use the UPS power supply before using it? I believe that the installation process of UPS uninterruptible power supply is a challenge for most engineering technicians. The following provides a detailed explanation of the “UPS Power Supply Installation Process Specification” from several aspects, including installation precautions, installation procedures, and usage precautions.
1. Installation precautions
The quality of UPS power installation directly affects the long-term operation of the UPS system, especially for large and medium-sized UPS power supplies. Therefore, the planning and installation process of large and medium-sized UPS power supplies should be standardized.
Generally speaking, UPS power supply installation mainly considers the following factors:
Power grid situation, load capacity, characteristics, usage environment, grounding situation, wiring, switch capacity, etc.
(1) Power grid situation
Mainly including the range of voltage fluctuations in the power grid, parking frequency, etc. to determine the backup time of UPS uninterruptible power supply. If necessary, other protective measures can be added in front of the UPS power supply.
(2) Usage environment
Temperature: required to be between 0 ℃ and 40 ℃;
Humidity: required to be 10% -90%;
Dust falling: The surrounding environment of UPS power equipment should be kept clean to reduce the corrosion of harmful dust on the internal circuits of UPS; Structure: When configuring UPS power with long delay, the battery may be heavy, and the floor load-bearing issue should be considered;
Space size: It should be ensured that there is a certain amount of space for engineering personnel to use when maintaining the UPS uninterruptible power supply.
(3) Grounding situation
In order to ensure stable and reliable operation of computer systems, prevent parasitic capacitance coupling interference, and protect equipment and personal safety, a good grounding system is necessary. In the grounding system, the grounding resistance is used to indicate the quality of grounding. Generally, a grounding resistance of less than 5 Ω is ideal.
