The Eaton® 93PM-L Integrated Accessory Cabinet-Bypass (IAC-B) is designed for use with the Eaton 93PM–L
160/200 kW (208V) Series Uninterruptible Power Supplies (UPSs). The IAC-B provides maintenance bypass
functions with configurable features, enabling adaptation and expansion without costly electrical rework. The
93PM-L IAC-B is available in 160 kW or 200 kW rated versions, in either 2–Breaker, 3–Breaker or 4–Breaker
configurations.
The IAC-B 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.
Figure 1 shows the Eaton 93PM–L 160/200 kW IAC-B.
NOTE Startup and operational checks must be performed by an authorized Eaton Customer
Service Engineer, or the warranty terms specified in paragraph 9.1 Warranty become
void. 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-B functions:
• Two breaker configuration: The bypass sidecar contains only a Maintenance Bypass (MBP) and
Maintenance Isolation (MIS) breaker. This allows Maintenance bypass for system repair or maintenance.
• Three breaker configuration (used with single-feed systems): Maintenance Bypass (MBP) and
Maintenance Isolation (MIS) breakers, and a Bypass Input Breaker (BIB) enable power to completely
bypass the UPS. The UPS can then be safely serviced or replaced without interrupting power to critical
systems.
• Four breaker configuration (used with single and dual-feed systems): Maintenance Bypass (MBP) and
Maintenance Isolation (MIS) breakers, and a Bypass Input Breaker (BIB) enable power to completely
bypass the UPS. A Rectifier Input Breaker (RIB) provides a convenient method for removing power from
the UPS when using the maintenance bypass to supply the load. The UPS can then be safely serviced or
replaced without interrupting power to critical systems.
Figure 3 and Figure 4, show the IAC-B installed adjacent to the UPS cabinet.

• The IAC-B is designed to be installed in a line-up-and-match configuration:
–The provided UPS to IAC-B breaker wiring is routed through the side panels between the UPS and the
IAC-B.
–The wiring to the bypass input, rectifier input and the output wiring is routed using external conduit
through top or bottom entry conduit plates.
• To reduce installation time, connections to the input and output are made to easily accessible bus bar
terminals via 2–hole crimp lugs (customer provided) located at the top and bottom of the cabinet.
• Top exhaust or rear exhaust venting is available.
• The cabinet is leveled using the provided leveling feet and can be secured in place using the optional floor
mounting bracket kit.
A line-up-and-match IAC-B is installed adjacent to the UPS. The IAC-B may be installed on the right side or the
left side of the UPS cabinet as viewed from the front of the cabinets. See Figure 3 or Figure 4 for
line-up-and-match configuration views.
