Maintenance Bypass Switch (MBS)

The purpose of a Maintenance Bypass Switch (MBS) is to isolate all AC input and output supplies from a UPS to allow maintenance technicians to safely work on the equipment, while the critical load equipment continues to be powered from the input supply, normally raw mains, without interruption.
DC supplies are not disconnected by the MBS as they are fitted with their own specialised isolators.
All MBS feature an electrical/mechanical interlock to prevent UPS damage due to improper switch operation.

External MBS allows users to isolate power from UPS cabinet, including incoming and outgoing connections. It also permits the user to replace the UPS without shutting down the critical load. An external Bypass Switch may also be required due to OH&S requirements.
