MBM INSTALLATION 4.3.5 Standalone Power Wiring Installation NOTE The MBM cabinet is shipped with a debris shield covering the ventilation grill on top of the unit. Do not remove the debris shield until installation is complete. However, remove the shield before using the MBM. Once the debris shield is removed, do not place objects on the ventilation grill. NOTE All power wiring to the MBM must be run in customer-supplied conduit.
MBM INSTALLATION NOTE When installing an MBM, a minimum of two separate feeds with upstream feeder breakers, or a single feed with two upstream feeder breakers, must be provided: one for the UPS or rectifier input breaker (RIB) (if installed) and one for the maintenance bypass input. DO NOT use a single feed or a single feeder breaker to supply both the UPS or RIB and the maintenance bypass.
MBM INSTALLATION 20. When all wiring is complete, reinstall the safety shield panels removed in previous steps. 21. Reinstall the doors removed in previous steps and secure with the retained hardware. 22. Close the doors and secure the latch. 4.3.6 Standalone TB1 Interface Wiring Installation WARNING Hazardous voltages are present near the user interface terminal area if the MBM is not totally disconnected.
MBM INSTALLATION 4.3.7 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. Table 4‐2.
MBM INSTALLATION 4.5 Completing the Installation Checklist The final step in installing the MBM is completing the following Installation Checklist. This checklist ensures that you have completely installed all hardware, cables, and other equipment. Complete all items listed on the checklist to ensure a smooth installation. Make a copy of the Installation Checklist before filling it out, and retain the original.

Chapter 5 Figure Understanding MBM Operation The Maintenance Bypass Module (MBM) 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. The MBM consists of a maintenance bypass breaker (MBP), a maintenance isolation breaker (MIS), an optional bypass input breaker (BIB), and an optional rectifier input breaker (RIB).
UNDERSTANDING MBM OPERATION Key A is removed from the the solenoid lock, inserted in the MBP key A slot, and the MBP closed. This sequence inhibits the MBP from being closed until the UPS is in Bypass mode, preventing the bypass source and the UPS inverter from being connected in parallel. Key B is removed from the MBP, inserted into the key B slot on the MIS, and the MIS opened. When the MIS is locked using key B, key A from the MIS to be removed and inserted into the solenoid lock and locked in place.
UNDERSTANDING MBM OPERATION 5.4 Maintenance Bypass Mode Current Flow An MBP is used to safely supply utility power to the critical load during periods of UPS maintenance or repairs. The bypass source supplies the commercial AC power to the load directly. When the MBP is closed, the load is wrapped around the UPS while power is still supplied to the load by the UPS through the MIS. The MIS is then opened, isolating the UPS from the bypass power source.
