UPS-Mounted Bypass Switch Installation

This chapter describes the Maintenance Bypass Module (MBM) and Power
Distribution Module (PDM) installation. Both modules have a Make-Before-Break
(MBB) maintenance bypass switch.
If you purchased an optional MBM/PDM, attach the module to the UPS before any
wiring installation. All hardware is supplied in the accessory kit.
To attach the optional MBM/PDM to the UPS:
1. Remove the connecting plate between the top cabinet and the cabinet below it
on the UPS rear panel (see Figure 14). Discard the plate. Retain the screws for
later use.
2. Remove the lowest top cover screw on each side of the UPS and discard.
