Planned preventative maintenance and repair services, tailored to your specific needs. Preventative Maintenance Visits (PMVs) are one of the key services included in an ongoing UPS maintenance plan. It is recommended that a UPS system has a minimum of one PMV every year. The purpose of a PMV is to provide a detailed inspection of the unit, which helps to identify and rectify any problems. It also enables our service engineers to upgrade software and perform system tweaks to optimise operational performance and efficiency.

A PMV incorporates a visual test of the UPS, plus a physical check of all electrical connections. Particular attention is paid to circuit breakers, contactors, fuses, cabling, transformers, printed circuit boards, capacitors, fans and communications slots. Batteries are inspected for signs of damage, corrosion or leaks, with all terminal connections checked to ensure they are at the correct torque setting. Engineers also carry out several mechanical tests on the functionality of the UPS, recording the system’s operating state and vital electrical measurements. In addition, a PMV includes a download and full review of the UPS performance history logs, as well as ensuring the unit has the latest firmware installed.
