Chapter 7 Maintenance Bypass
This chapter provides maintenance bypass information for the Eaton 9PX
PowerPass Distribution Modules (PPDMs).
NOTE Refer to the 9PX UPS/EBM user's guide for operation information.
The Maintenance Bypass feature allows you to remove the UPS while
providing power to your protected equipment. This feature is useful
when replacing the UPS for maintenance or upgrades.
The Maintenance Bypass feature is resident on the 9PXPPDM1 and
9PXPPDM2 models.
NOTE You can assemble a system configuration that provides maintenance bypass by
adding a 9PX Maintenance Bypass (MBP). See Figure 32 on page 42 for an illustration of that
configuration.
Using Maintenance Bypass
To transfer your equipment to maintenance bypass (AC Line operation)
and remove the UPS:
1. Using the UPS LCD menu (Control > Go to Bypass), place the UPS
in Bypass mode. The
indicator displays, indicating the UPS is in
bypass mode.
2. On the 9PX PPDM front cover, unsnap and remove the square
center cover.
3. Turn the bypass switch on the 9PX PPDM to the BYPASS position
(see Figure 34). The 9PX PPDM is now powering your equipment
from utility power.
