UPS-Mounted Bypass Switch Installation

This chapter describes the Maintenance Bypass Module and Power
Distribution Module installation. Both modules have a
Make-Before-Break 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. Use the following procedure 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 13). Discard
the plate. Retain the screws for later use.
2. Remove the lowest top cover screw on each side of the UPS and
discard.
