When working with data center and commercial facility electrical systems, shocks of 100mA to more than 2,000mA are possible—definitely in the realm of serious harm to humans and property. Energized electrical equipment also presents the risk of arc flash caused by electrical faults that produce powerful explosions. When dealing with commercial and industrial electrical systems, such as uninterruptible power systems (UPSs) and their batteries, data center and facilities managers need to be aware of these risks, especially since some repair and maintenance procedures require working with a unit that is still energized. There are ways to minimize the risks to employees, equipment and the field technician performing the service.
This paper answers some common questions about UPS maintenance, how to reduce the risks associated with servicing UPSs and batteries, and how to qualify a UPS service provider.
When designing a power protection scheme for their data center, IT and facilities managers must ask themselves whether a distributed or centralized backup strategy makes more sense. Unfortunately, there is no easy answer to that question.
Companies must weigh each architecture’s advantages and disadvantages against their financial constraints, availability needs and management capabilities before deciding which one to employ.
This white paper will simplify the decision-making process and lessen the potential weaknesses of whichever strategy you ultimately select.
