The Eaton 9PXM UPS input power is hardwired through a conduit to either a main power source circuit breaker or to an optional
bypass switch. It is recommended that you install an Eaton® Bypass Power Module (BPM) to enable power transfer during
maintenance or UPS downtime.
WARNING
Risk of electrical shock. Only qualified service personnel (such as a licensed electrician) should perform the
electrical installation in this section.
NOTE For installation and configuration of the Eaton bypass switch refer to the manual “Eaton
Bypass Power Module (BPM) User’s Guide P-164000628” supplied with the switch or
on the Eaton website https://www.eaton.com/9PXM .
If a bypass switch is used, both UPS input and UPS output must be hardwired through separate conduits to the
bypass switch, as shown in Figure 14.
