Bypass Module Installation
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 http://www.eaton.com/Eaton/index.htm.
UPS Connections
To prevent electrical shock or damage to the equipment, verify that the Eaton 9PXM UPS is OFF
before you remove the terminal covers. The circuit breaker or disconnect switch must also be OFF
at the AC input service panel.
To install the UPS with an external bypass switch:
1.
Mount the bypass switch within sight of the UPS. If you do not have an Eaton bypass switch or the fuse
box or panel is out of sight, you must install a separate disconnect switch next to the UPS.
2. The bypass switch should be mounted securely to a sturdy surface. You may need to turn the cabinet 90
degrees (on its side) to enable operator access to the switch handle.
3.
Remove the screws on the bypass switch front cover and remove the cover. Remove any packing material
inside the bypass switch.
4.
Remove the blank plate in the bottom of the bypass switch for AC Line Input, AC to UPS Input, AC from
UPS Output, and AC to the UPS load.
5.
Unscrew and remove the rear AC Input and Output upper terminal cover(s) of the UPS. See Figure 15.
NOTE 1
Refer to "Circuit Breaker Input Current Ratings" on page 16 for breaker, terminal
block, and wire sizing.
NOTE 2
Connection diagrams can be found on Figure 20 on page 24.
