Warning Uninterruptible Power Supply System Label

This warning label identifies an installation incorporating an uninterruptible power supply (UPS). It alerts electricians, technicians and other personnel that connected equipment may remain energised from stored battery energy even when the normal mains supply has been disconnected.

UPS and critical-power applications

Suitable for switchboards, server and communications rooms, control systems, medical or industrial equipment areas and other installations where a UPS provides temporary or continuous backup power.

Power can remain present after mains isolation

A UPS is specifically designed to maintain supply when the normal source is interrupted. As a result, turning off an upstream mains switch does not necessarily de-energise the UPS output, internal batteries or connected critical circuits.

Follow the UPS isolation procedure

The correct shutdown sequence depends on the UPS design, bypass arrangement, battery configuration and connected equipment. Follow the manufacturer's instructions and site-specific electrical procedure before service work or access.
