The Eaton 9PXM easy replace feature lets you replace a power module without disconnecting the load or
damaging the UPS.
NOTE
The UPS may switch to internal Bypass mode if the remaining power modules are
insufficient to supply the required power. If empty slots exist, install replacement
modules before removing original ones.
Use care in removing and installing power modules. To remove a power module:
1.
Remove the front cover.
The cover has magnetic latches on the left and right sides that hold it in place.
2.
Loosen the captive screws at the sides of the power module and slowly pull the power module out of the
cabinet.
3.
Treat the original and replacement power modules with care to avoid damaging connectors or internal
circuitry. Label the original power modules with masking tape or some other identifier. Record the serial
number of the replacement power modules for your warranty.
4.
Insert the replacement power module by sliding it carefully into the cabinet.
5.
Tighten the captive screws to the UPS cabinet.
6.
Replace the front cover.
