In-house technicians generally can perform scheduled testing and documentation for uninterruptible power systems (UPS), though managers can opt to bring in an outside agency specializing in thermal testing.

When opting to have qualified in-house technicians test and maintain UPS equipment, managers must be sure these individuals understand and adhere to requirements of the National Fire Protection Association (NFPA) 70E, Electrical Safety in the Workplace.

Whenever UPS testing occurs, technicians either should place the system into bypass mode or transfer the load to the redundant system, if designed this way. They must be especially cautious when maintaining the equipment to prevent an unscheduled outage. The technician also must be familiar with equipment, manufacturers’ testing requirements, specifications and safety precautions.

In some cases, as much risk is involved in testing and maintaining the UPS equipment with unqualified personnel as when performing no maintenance at all.
