Planned visits
Service plans can include quarterly visual checks, cleaning, log review and infrared scanning, followed by deeper annual inspection and battery assessment.
4ON CRITICAL INFRASTRUCTURE
UPS Maintenance
UPS maintenance is built around proving that the complete power path will work when normal supply disappears. We combine scheduled inspections, battery assessment, load testing, changeover observation and emergency support.
Engineering reports
After service work, the findings and recommended remedial actions are documented with supporting photographs where useful.
Load bank testing
Portable load equipment can reproduce demanding operating conditions so UPS output and battery autonomy can be checked under controlled load.
Battery condition monitoring
Live and periodic battery measurements can help identify deterioration early and support sensible replacement planning.
Agreed parts limits
Maintenance contracts can include pre agreed spending limits for common parts and consumables, allowing urgent work to progress without unnecessary delay.
Changeover monitoring
Where maintenance requires transfer to generator or another source, critical components can be monitored before, during and after the changeover with a risk review and pre check.
Continuous support
The support desk remains available around the clock for faults, scheduling and urgent maintenance issues.
