Important considerations when buying and installing a UPS

All uninterruptible power supply (UPS) models are not created equal, nor are their installation requirements. Large, mid-range modular and smaller plug-and-play models may all have individual considerations. Requirements can also differ amongst UPS back-up topologies and deployment methods. If you need more help understanding the differences between UPSs and determining the optimal model for your particular environment or application, read our UPS FAQ.

If you've already selected your battery back-up and are preparing for installation, the following 10 tips will help ensure that the process goes smoothly:

1) Engage an electrician

Any hardwired UPS should be installed by a licensed electrician, preferably one who is familiar with the particular model. While smaller plug-and-play UPSs enable installation by users, in these instances it is still wise to have a second set of eyes review the work.

2) Check your connections

During shipment, it is not uncommon for some connections to shift within the UPS. Although often not visible, loose connections can lead to sparking of equipment following installation, which in turn can cause charring or even fires. This is another reason why electricians are recommended for UPS installation, as they can quickly identify and correct any loose connections. Post-installation, proper monitoring and preventive care will help detect and resolve any potentially problematic electrical connections within the UPS. 


3) Be environmentally aware

It is important to carefully consider the location and environment where a UPS will be installed, always avoiding potential triggers such as heat, humidity and dust.

  • Proper air flow is essential, so it is critical to never block UPS vents.
  • Keep in mind that the optimal operating temperature for a UPS with lead acid batteries is 25˚C/77˚F. To avoid overheating, never place a UPS in direct sunlight.
  • The ability to receive advanced notification of a pending problem such as overheating equipment can represent the difference between prompt resolution and complete disaster. The Eaton Environmental Probe (EMP) collects temperature and humidity readings in a rack enclosure, enabling you to monitor environmental data remotely using a standard web browser.

4. Limit UPS access

While you may think your UPS is secure if installed in an out-of-the-way location, don't leave that conclusion up to chance. From employees attaching additional devices to cleaning staff plugging in a vacuum cleaner, these and other incidents can quickly cause a UPS to overload. For that reason, it is essential to properly secure the UPS and prevent unauthorised access. 

For smaller UPSs, consider a wall-mount enclosure for a secure installation, such as the MiniRaQ by Eaton, which offers a 50 percent smaller footprint than competitive solutions. 


5) Don't skimp on a warranty/service plan

Depending on the UPS model, a standard warranty of two to five years will generally be included. But it is wise – and potentially quite cost-effective – to consider purchasing an extended warranty. In addition to providing expedited replacement parts and batteries, extended warranties can save time and money by minimising business interruption and the cost of downtime.

Performing factory-recommended preventive maintenance is essential for optimal performance and continued reliability of a UPS. To minimise the risks of downtime and extend the life of your unit, Eaton offers a wide variety of UPS service plans.

6) Batteries need love too.

Batteries represent the heart of any UPS system – but also the most vulnerable part. The leading cause of UPS failure and load loss, valve-regulate lead acid (VRLA) batteries require replacement every three to five years on average. Knowing how to properly maintain and manage batteries is key to extending their service life.

A preventive maintenance plan is amongst the most successful and cost-effective means of safeguarding UPS batteries. Regularly scheduled service allows trained technicians to inspect, test, calibrate and upgrade battery components, ensuring factory-specified performance and longevity.

7) Let's hear it for lithium-ion

While valve regulated lead acid (VRLA) batteries have long been the industry standard for UPSs, lithium-ion batteries are poised to become the preferred choice in IT applications, offering 2-3x longer lifespan, 3x faster recharge and up to 40% less weight. Lithium-ion UPSs such as the Eaton 5P save time and money while reducing risk throughout the lifecycle of the UPS. 

8) Invest in a network card

A UPS network management card can improve business continuity by providing warnings of pending issues and helping to perform orderly shutdown of servers and storage. Using a network card is the best way to manage a single UPS. An Eaton network card is essentially its own server, so it records event history, sends emails and text message alerts, and provides remote access to real-time status.

With better speed and cybersecurity, the Eaton Gigabit Network Card is the first network card to meet UL and IEC cybersecurity standards, providing a Gigabit Ethernet connection and enabling secure UPS monitoring over HTTPS web browser interface, SNMP v1/v3 protocol and email alarms.​

9) Integrate a maintenance bypass

Providing a simple and effective means for bypassing a UPS while maintaining power to the load, a maintenance bypass allows you to service or replace the unit without shutting down connected equipment.

10) Avoid surprises with PredictPulse

Organisations managing multiple UPSs can reap significant advantages from a remote monitoring service such as PredictPulse. Mitigate downtime risks associated with battery and capacitor failure, proactively replace components before failure, and extend asset life using real-time data. PredictPulse monitors your power devices and alerts Eaton personnel if an issue is detected. Eaton then automatically dispatches a field technician to the affected site when needed.

See how a multibillion-dollar global retailer with more than 300 stores used PredictPulse to overcome its routine battery and service issues.
