MBP, MIS, BIB, and RIB Current Settings
The MBP, MIS, BIB, and RIB are adjustable trip breakers set at the factory. These
breakers are designed to control the input and output to the UPS.
Verify the settings of the installed MBP, MIS, BIB, and RIB match the values listed in
Table 4‐2 and Table 4‐3. Use the continuous current (Ir) dial on each breaker to adjust
the trip current as necessary.

Initial Startup
Startup and operational checks must be performed by an authorized Eaton Customer
Service Engineer, or the warranty terms specified on page NO TAG become void. This
service is offered as part of the sales contract for the MBM. Contact an Eaton service
representative in advance (usually a two-week notice is required) to reserve a
preferred startup date.
