Uninterruptible Power Supply (UPS) systems are essential for maintaining a steady power source for your critical equipment during power disruptions, fluctuations, or outages. Whether you’re running a data centre, office, healthcare facility, working within manufacturing, or managing major transport lines a properly maintained UPS can make all the difference in keeping your operations running smoothly.
However, just like any other technology, UPS systems require regular upkeep to ensure they perform optimally when the power goes out. Below, we’ve compiled answers to some of the most frequently asked questions about UPS maintenance, to help you understand how to keep your system in top shape.
How often should I service my UPS?
UPS systems require regular checks to ensure they’re ready for emergencies. Ideally, you should conduct basic checks on your UPS system every month. This involves inspecting the battery status, monitoring the load, and ensuring there is enough ventilation.
More importantly, you should schedule professional maintenance bi-annually. In line with SFG20 guidelines, it is a legal requirement to have your UPS systems tested every six months to ensure full compliance. While some might think an electrician can handle this, it’s highly recommended to have your UPS tested by a qualified UPS engineer to ensure accurate diagnostics and prevent costly failures in the future – after all, you wouldn’t find your local car mechanic servicing a Formula 1 car, so why would you ask an electrician to service your UPS instead of an expert?
Read our blog on “No Rules, No Power: The Grey Area of UPS Maintenance in the UK” which explores why UPS maintenance responsibility needs clarity. There is no governing body or mandatory certification for UPS engineers in the UK, so general electricians, often without the necessary expertise, are sometimes assigned to maintain and test UPS systems. We explain why this needs to change to ensure UPS systems are serviced and maintained to ensure optimum performance when they are needed most. How often should I replace the batteries in my UPS?
UPS batteries should be replaced every 3-5 years depending on usage and battery type. There are a few factors that can influence this such as battery type, usage frequency, temperature and performance.
Can I replace UPS batteries myself?
While some UPS systems come with user-replaceable batteries, it’s important to consult a UPS expert if unsure. Replacing UPS batteries yourself may seem straightforward, but incorrect installation can lead to malfunction or even safety hazards like overheating or fire. Professional assistance ensures that the batteries are installed correctly and that your UPS remains fully operational. A qualified technician will also be able to check for any other potential issues that could affect the system’s performance, such as faulty wiring or worn-out components.
How long does a UPS last?
Most UPS systems are designed to last around 8 to 10 years if they are properly maintained. However, regular maintenance by UPS experts plays a crucial role in maximising their lifespan. Neglecting routine checks and not replacing batteries at the recommended intervals can significantly shorten the life of your UPS.
If you’re nearing the 8-year mark with your UPS, having a professional evaluate its condition is a good idea. Many systems can last longer with proper care, but it’s important to keep an eye on performance and battery health. Book a service with us here.
Who would benefit from a UPS?
A wide variety of individuals and businesses can benefit from having a UPS system in place:
- Data Centres & IT Infrastructure: These facilities rely heavily on constant power to ensure the availability of critical data and services.
- Healthcare Providers: Medical devices and equipment often depend on a stable power supply, especially in emergencies.
- Businesses & Offices: Offices that rely on computers, phones, and other digital tools will benefit from having backup power during outages.
- Emergency Services: Maintain communication and operational systems during power failures to ensure continuity of service.
- Financial Services: Ensure uninterrupted transactions, data security and system access.
- Educational Institutions: Keep online learning platforms and administrative systems running.
What consequences are there if I have a power outage and I do not have a properly maintained UPS?
If your UPS is not properly maintained or malfunctions during a power outage, you risk losing access to critical systems and equipment. A UPS is designed to operate seamlessly without notice, stepping in when power outages strike unexpectedly. However, without regular maintenance, your investment loses its value. To truly protect your business and ensure peace of mind, it’s essential to keep your UPS in top condition. A UPS that’s not maintained is nearly as unreliable as having no backup at all.
Potential issues that could arise include:
- Data Loss: Power interruptions can corrupt or permanently destroy unsaved work, leading to lost data and costly recovery efforts.
- Equipment Damage: Power surges or sudden shutdowns can damage sensitive equipment, such as computers, servers, and medical devices.
- Downtime: For businesses, even short periods of downtime can lead to significant financial losses and productivity setbacks.
- Security Risks: In some cases, a lack of power can compromise security systems, leaving you vulnerable to unauthorised access.
What UPS do I need?
Choose one based on the power requirements of your devices and the type of protection needed. When choosing a UPS, consider its capacity (VA rating) based on your devices’ total power needs, the number of outlets for your equipment, and the runtime you require during outages. Ensure it provides the necessary protection (surge or battery backup), fits your space, and offers communication features for remote monitoring if needed. Also, factor in battery maintenance, brand reliability, and warranty options, while balancing cost with long-term benefits.
How much run-time do I need?
Run time will depend on the equipment you are protecting and how critical this equipment is for your infrastructure. A small office-based UPS may only need a few minutes for you to safely save your work and log off during a power outage. In contrast, for a larger office or data centre, you may require an extended run-time for another power source such as a generator to kick in or an emergency lighting system to provide lighting during emergencies that allows all people to safely exit the building.
This can be discussed with BCL during the initial design phase of the project to understand what it is you are looking to protect and the realistic run-time that will be appropriate for your business. The amount of space available may also determine your maximum run-time available. A longer run-time will require more batteries which in turn requires more space. Again, this can be discussed with us at the design phase to understand the capabilities and limitations of the space provided.
How big should my UPS be?
This will be dependent on the size of the load that you are protecting. We would recommend sizing the UPS to around 20-25% larger than the load that you are expecting to allow for any slight deviations in the load. If you are looking to increase the load in the future then maybe a larger system to start with is best as it will give you the flexibility to add to your infrastructure without the need to replace the UPS.
Other factors to consider are any in-rush currents. These are typically found in mechanical loads as there is usually an initial spike in current to initially get the component moving. For example a pump or fan. It is always best to understand the in-rush current before sizing your UPS to ensure the UPS is suitable for your needs.
Is a rack-mounted UPS better than a floor-standing UPS?
This will depend on your specific setup. Generally, a rack-mounted UPS is more compact, but when additional battery packs are added, it can take up significant space in the rack, potentially limiting room for other equipment. In such cases, a floor-standing UPS positioned beside the rack might be a better option, as it allows you to fit all your gear into the rack while still providing protection.
It’s crucial to assess how much available rack space you have before selecting a rack-mounted UPS. Similarly, if you opt for a floor-standing UPS, it must be placed in a suitable location. It should be in a well-ventilated room, with enough clearance around it for proper heat dissipation and airflow – avoid placing it directly against a wall.
