Eaton Bypass Power Module (BPM) User’s Guide P-164000628—Rev 2 www.eaton.com/powerquality 1
Chapter 1 Introduction
The Eaton®Bypass Power Module (BPM) is designed to be a maintenance bypass switch that also contains
flexible output power distribution and mounting options. The BPM is a bypass module that can be used with a
variety of Eaton UPS models including the 9170+, 9155, and 9PX SP.
The BPM provides added reliability to Eaton uninterruptable power supply (UPS) systems by ensuring
seamless, uninterrupted, no-break transfer as well as a lock-out/tag-out (LOTO) feature to ensure the greatest
safety for UPS technicians and electricians. The BPM also offers output distribution in order to simplify wiring
in a rackmount IT environment, potentially removing the need for a panelboard, breakers, and conduit for
distribution.
Although the BPM is designed to be safe, the bypass can carry high levels of voltage and current. The BPM
should only be operated by an experienced user, familiar with UPS behavior and functionality. Installation for
models requiring hardwire connections should be performed by a qualified electrician following local electrical
codes. Please refer to the installation chapter of your UPS manual for the BPM wiring diagram.
Bypass Overview
The BPM has three operating positions (see Table 1). Failure to understand the correct bypass sequence and
position may cause the critical load to be dropped. Consider both the operating state of the UPS and the BPM
when protecting your critical loads.
NOTE In the UPS or LINE position, AC input power is still connected to the input terminals
inside the UPS.

Table 1. BPM Positions
Switch
Position Description
UPS The normal operating state of the system occurs when the BPM switch is in the
UPS position. Utility power is fed to the bypass, where power is then fed to the
UPS. The UPS provides critical battery backup and power conditioning and power
is then fed back to the bypass switch and then the critical load.
LINE When the switch is in the LINE position, utility power is directly connected to the
critical load and the output of the UPS is disconnected. In this state the UPS
remains powered, which is often beneficial for troubleshooting, obtaining logs, or
updating firmware.
SERVICE Like the LINE position, the SERVICE position connects the load directly to AC
input power and disconnects UPS output; however, because SERVICE also
disconnects AC input from the UPS, this is the appropriate position for UPS
maintenance or repair. In the SERVICE position, the UPS can be completely
removed from the system.

WARNING
Risk of electrical shock. Only qualified service personnel (such as a licensed electrician) should
perform the electrical installation.
CAUTION
To prevent electrical shock or damage to the equipment, verify that the Eaton UPS is OFF before
you remove the entrance panel. The circuit breaker or disconnect switch must also be off at the AC
input service panel. Also, turn OFF the AC disconnect and bypass switches before you connect
any wires to the bypass switch terminal strip.

CAUTION
lThe BPM distributes high density power in a small form factor.
lRead the complete installation procedure before beginning any electrical wiring.
To install the BPM in a rack:
1. Install the 4-post rail kit included with the BPM (see Figure 2).
Figure 2. Install Rail Kit
2. Place the BPM on the rails and push the BPM into the rack.
Verify that the breakers are facing the front of the rack and the BPM wiring terminals are facing the rear of
the rack.
3. Push the BPM past the back of the rack to allow access to the rear wire access-point covers and the wire
access panel cover (see Figure 3).
Figure 3. Push BPM into the Rack
4. Remove the wire access-point covers (see Figure 4).
