Installing an Uninterruptible Power Supply (UPS) system is a critical step in protecting essential building infrastructure from unexpected power disruptions. Whether you’re responsible for a hospital, data centre, manufacturing facility or commercial building, a correctly installed UPS system helps maintain operational continuity when mains power fails.
However, understanding UPS installation standards can be challenging. With electrical regulations, industry standards and technical requirements to consider, how can Facilities Managers be confident their UPS installation meets the necessary requirements?
Here’s what you need to know before installing a UPS system.
What Standards Apply to UPS Installation in the UK?
Several regulations and recognised standards influence how UPS systems should be designed, installed and maintained in the UK.
BS 7671: IET Wiring Regulations
BS 7671 sets out the requirements for electrical installations in the UK. It covers essential considerations such as electrical protection, earthing, cable sizing and safe isolation.
UPS installations must comply with the applicable requirements of BS 7671, ensuring the system integrates safely with the building’s electrical infrastructure.
BS EN IEC 62040: Uninterruptible Power Systems
The BS EN IEC 62040 series addresses UPS safety, electromagnetic compatibility and performance.
Relevant parts include:
- BS EN IEC 62040-1: Safety requirements for UPS systems.
- BS EN IEC 62040-2: Electromagnetic compatibility requirements.
- BS EN IEC 62040-3: Performance requirements and testing methods.
These standards help establish whether UPS equipment meets recognised safety and performance requirements.
Health and Safety Legislation
The Electricity at Work Regulations 1989 require electrical systems to be constructed, maintained and operated to prevent danger, so far as reasonably practicable.
For Facilities Managers, this reinforces the importance of selecting competent installation providers and maintaining appropriate inspection and maintenance records.
Is There a Specific Certification for UPS Installation?
One common misconception is that there’s a single, mandatory certification qualifying a company to install UPS systems.
In reality, there’s no universal UK certification specifically covering every UPS installation.
Instead, providers must demonstrate appropriate electrical competence, technical knowledge and an understanding of relevant regulations.
Schemes such as NICEIC or NAPIT can provide evidence of electrical installation competence, but registration alone doesn’t establish a provider’s capability to design, configure and commission complex UPS systems.
UPS installations require knowledge of battery systems, load characteristics, bypass arrangements and manufacturer-specific commissioning procedures.
Before appointing a provider, ask about their experience with comparable UPS installations, technician training and commissioning processes.
Five Essential Considerations Before Installing a UPS System
A successful UPS system installation starts long before equipment arrives on site.
1. Correct UPS Sizing
An incorrectly sized UPS can compromise reliability and create unnecessary operating costs.
Your installation provider should assess connected loads, power factor, potential inrush currents and future expansion requirements.
A UPS system audit can help establish the appropriate capacity and identify potential installation challenges.
2. Battery Runtime Requirements
How long must your critical systems remain operational during a power failure?
Some facilities require sufficient runtime for an orderly shutdown. Others need extended backup until a generator starts or mains power returns.
Battery capacity must reflect actual load requirements, operating conditions and the intended autonomy period.
3. Bypass Arrangements
Maintenance bypass arrangements allow authorised personnel to isolate UPS equipment while maintaining power to connected loads, where the system design permits.
Facilities Managers should confirm that appropriate bypass arrangements are included, particularly where planned maintenance must take place without interrupting operations.
4. Installation Environment
UPS equipment requires suitable ventilation, temperature control, physical access and electrical infrastructure.
Poor environmental conditions can accelerate UPS battery deterioration and affect system performance.
The installation assessment should also consider floor loading, cable routes, fire safety requirements and manufacturer clearances.
5. Commissioning and UPS System Testing
Commissioning verifies that the installed system operates as intended.
A thorough UPS system test should cover relevant functions, including alarms, operating modes, bypass operation and battery performance.
Testing should follow manufacturer procedures and an agreed commissioning plan, with results documented before handover.
Why Ongoing UPS Maintenance Matters
Meeting UPS installation standards is only the beginning of protecting critical infrastructure.
UPS batteries deteriorate over time, electrical connections can develop faults, and operating conditions may change as facilities expand.
Scheduled UPS maintenance helps identify potential problems before they affect power availability.
A proactive maintenance plan should include battery condition assessments, electrical inspections, alarm checks and appropriate functional testing.
Facilities Managers should also retain commissioning documents, maintenance records and UPS system test results to support operational planning and demonstrate responsible system management.
