3.5.1 Maintenance Bypass Switch
The Maintenance Bypass Switch (MBS) enables power to completely bypass
and isolate the UPS so that the UPS can be safely serviced or replaced without
interrupting power to critical systems.
An internal maintenance bypass switch is provided as a factory installed option
for 30–150 kW units.
Alternatively, MBS solutions are also available in an external enclosure as
accessory items.
External Maintenance Bypass Switch Panel
The external MBS is enclosed in its own separate cabinet, which can be either a
wall-mounted or stand-alone cabinet depending on the MBS power rating. The
MBS includes a Maintenance Bypass Switch (MBS) and a UPS Output
Maintenance Isolation Switch (MIS). The panel may additionally include one or
two input breakers: one for the rectifier input (RIB) and another for bypass input
(BIB). It also includes auxiliary contacts to report the status of the switchgear to
the UPS.
For external MBS installation instructions, see a separate manual.
