Standards applicable to UPS systems and installations

The question of standards relating to UPSs involves many aspects. There are safety, EMC compliance and performance considerations for the UPS equipment itself, and limitations for the equipment’s impact on the power network. Lead-acid batteries have their own regulations relating to selecting, safe operation, testing, maintenance and replacement. Further aspects of the UPS installation are also subject to regulation; these include environmental protection (IP) standards, wiring regulations, equipotential bonding and earthing, and other factors.
