UPS power maintenance six tips

Unpredictable faults may occur during the use of the UPS power supply, which can cause the UPS power supply to become unusable. Therefore, maintenance of the UPS power supply is indispensable, which can ensure that the UPS power supply reduces the occurrence of faults. Xiao Bian today to specifically introduce the UPS power maintenance skills, I hope to help everyone.

First, safety first.

Every time you perform UPS power maintenance, remember that life and physical safety should outweigh everything. When handling power supplies, even a small misoperation can cause serious injury or death. Therefore, when dealing with a UPS (or any power system in a data center), ensuring safety is a primary concern: including following the recommendations of the equipment manufacturer, focusing on facility-specific details and standard safety guidelines. If you are unfamiliar with some aspect of the UPS system or do not know how to maintain it, please seek professional help. Even if you understand the UPS system in your data center, it is still necessary to seek appropriate external assistance so that someone with calm mind can help you when it comes to some potential problems, so that you will not suffer from stress.

Second, adhere to regular maintenance.

Preventive maintenance in the data center should not be a whim for you, especially considering its potential downtime costs. For your data center UPS system and other systems, you should perform regular maintenance (in units of years, six months, or any time frame) and insist on implementing this maintenance plan. This includes a written (paper or electronic) filing list, which records the exact time of the next maintenance activity and the last maintenance.

Third, do a detailed record.

In addition to scheduling regular maintenance plans, your data center should also have a detailed maintenance record (for example, records of cleaning, repair, or replacement of certain parts), as well as details of related equipment found during the inspection process. When you need to report to the data center leader about the cost of maintenance or the cost loss caused by each downtime, cost tracking is also very helpful. A detailed list of tasks, such as checking battery corrosion, looking for excessive torque on the connecting wires, etc., helps maintain an orderly approach. All of these documents can be helpful when planning for equipment replacement, occasional repairs, and UPS troubleshooting. In addition to making records, it's important to make sure that these documents are always in a convenient and well-known location.

Fourth, the task assignment.

“You shouldn’t check last week?” “No, I think it should be your inspection.” To avoid this confusion of unclear responsibilities, it’s important to ensure that you have the right dedicated staff to take care of UPS maintenance tasks. Which staff member is responsible for checking equipment every week? Which staff member is responsible for contacting service providers and arranging annual maintenance plans (or adjusting maintenance schedules)? Specific tasks may have different principals, but be sure to know who is responsible for your UPS system.

Many UPS power supply maintenance items are best left to those who are familiar with UPS. Once again, safety is crucial: the danger of voltage in a UPS system can be fatal, so it is best to hire a professional and not risk the operation. Preventive maintenance is the key to all the data center operations, so many applications can be widely used, but the UPS system needs special attention because it needs stable power to provide your IT equipment in the short term. By performing regular maintenance schedules, it is easy to prevent downtime events due to exhausted batteries, capacitor failures, or clogged air filters, or even outdated firmware welding relays. You only need to carefully implement the above steps and take preventive maintenance procedures to help your data center avoid many future UPS troubles.

Fifth, perform regular inspections.

The above three recommendations apply to almost any part of the data center: No matter what the data center environment, it is good practice to strengthen security, schedule maintenance, and maintain good records. However, for UPS systems, there is a need for staff to perform certain tasks on a regular basis (these staff should be familiar with the basics of UPS operation). These important UPS maintenance tasks include the following:

1. Inspection of obstacles and related cooling equipment around UPS (or other energy storage) equipment.

2. Make sure that no abnormal operation has occurred or that the UPS control panel does not emit any alarm that is similar to an overload or that the battery is running out.

3, pay attention to see signs of battery corrosion or other defects. For those specific equipment, consult the manufacturer's guidelines and recommendations. In some cases, you should strictly implement the equipment manufacturer's maintenance advice (or hire a professional to do it).

6. It is possible to realize that the UPS power supply has failed to operate.

This seems obvious: any device with a finite probability of failure will eventually fail. Eaton’s report states: “Critical UPS components, such as batteries and capacitors, cannot always be kept in good condition.” So even if your power supplier provides the perfect power, your UPS room is completely clean and the UPS equipment is When the temperature is ideally running, the related components will still fail. Because of this, you need to maintain the UPS system.
