Vertiv’s program for capacitors & fans replacement is based on years of field data analysis and experience, thus representing the best method to achieve the highest reliability of your business-critical systems. Vertiv’s certified Customer Engineers perform on-site components analysis in order to verify their health status. Gathering data on electrical and environmental conditions, and combining them with expected components lifetime, allows to design a tailored maintenance schedule Our approach to safely scheduling capacitor replacement consists of replacing the bank of AC and DC capacitors before they age to the point where there is a significant probability of a capacitor short circuit Considering a proactive lifecycle management for UPS, fan replacement must be included as these components are subject to an aging process. The expected life of a fan depends on manufacturer specification, environmental conditions and specific UPS application
