The Eaton®Integrated Accessory Cabinet-Tie (IAC-T) is designed for use with the 93PM 50 kW and 100 kW
UPS. The IAC-T provides parallel tie or parallel tie with optional maintenance bypass functions with the
configurable features, enabling adaptation and expansion without costly electrical rework.
The IAC-T is housed in single free-standing cabinet with safety shields behind the doors for hazardous voltage
protection. The cabinet matches the UPS cabinet in style and color.
NOTE Startup and operational checks must be performed by an authorized Eaton Customer
Service Engineer, or the warranty terms specified on the product s resources page
become void. See Chapter 9 Warranty for details. This service is offered as part of the
sales contract for the UPS. Contact an Eaton service representative in advance (a
minimum two-week notice is required) to reserve a preferred startup date.

The following descriptions provide a brief overview of the IAC-T:
• Integrated Accessory Cabinet-Tie (IAC-T) – Module Output Breakers (MOB) 1 through 4 enable up to four
UPSs to be paralleled together for redundancy and/or increased capacity.
• Integrated Accessory Cabinet-Tie (IAC-T) with optional MIS – Module Output Breakers (MOB) 1 through 4
enable up to four UPSs to be paralleled together for redundancy and/or increased capacity. A Maintenance
Isolation (MIS) breaker provides output control to the critical load for the whole system.
• Integrated Accessory Cabinet-Tie (IAC-T) wit h optional MIS and MBP – Module Output Breakers (MOB) 1
through 4 enable up to four UPSs to be paralleled together for redundancy and/or increased capacity.
Maintenance Bypass (MBP) and Maintenance Isolation (MIS) breakers enable power to completely bypass
the UPS externally, allowing the UPS to be safely serviced or replaced without interrupting power to critical
systems.
Figure 1 shows the Eaton 93PM 50 kW IAC-T and 93PM 100 kW IAC-T.
11..22 IInnssttaallllaattiioonn FFeeaattuurreess
• The IAC-T is designed to be installed in line-up-and-match or standalone configurations:
–In line-up-and-match configurations input power wiring is routed through the side panels between the
UPS and the IAC-T.
–In standalone configurations input power wiring is routed using external conduit through top or bottom
entry conduit plates.
–Output wiring is routed using external conduit through top or bottom entry conduit plates.
• To reduce installation time, connections to the MOB and bypass inputs, and critical load output are made
to easily accessible mechanical lug terminals located on the breakers or at the front of the cabinet.
• Top exhaust or rear ventilation is available
• The cabinet can be leveled and secured in place using leveling feet
In a line-up-and-match two or four UPS parallel system the IAC-T is installed centered between the UPS
cabinets or other accessory cabinets. In a three UPS parallel system two UPS cabinets are installed to one side
of the IAC-T and one to the other side. All of the UPS cabinets cannot be installed to one side of the IAC-T
because of inter-cabinet wiring access constraints. See Figure 2 through Figure 4 for line-up-and-match
configuration views.
