EATON CORPORATION
Eaton 9390 Uninterruptible Power System
Integrated
Accessory
Cabinets for
customizable
configurations
Eaton offers several configura-
tions of Integrated Accessory
Cabinets (IAC) for use with the
9390 UPS. Major functions of
the IAC include: maintenance
bypass, parallel tie capability and
power distribution with combi-
nations up to (2) 42-pole panel-
boards and (6) sub-feed breakers
per IAC.
The IAC is primarily available in
two forms – either a 200 mm
(8”) sidecar bolted to the UPS
(maintenance bypass or tie) or
a 570 mm (22.5”) free-standing
cabinet (maintenance bypass, tie
or distribution). The size of the
IAC is primarily dependant on
function and rating.
IAC-SB and IAC-B
Maintenance bypass
Maintenance bypass configura-
tion (MBP) and maintenance
isolation (MIS) breakers enable
power to completely bypass the
UPS power module. The module
can then be serviced safely or
replaced without interrupting
power to critical systems. An
optional bypass breaker (BIB)
and rectifier input breaker (RIB)
provide a single wiring point
input to the UPS as well as a
convenient method for removing
power from the UPS when using
maintenance bypass to supply
the load.
