Power Module Replacement
The Eaton 9170+ hot‐swap 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 spring latches on the left and right sides that hold it
in place.
2. Loosen the thumbscrew on the module handle. Press down on the
latch release at the center of the module handle and pull the handle
down.
As the module handle fully extends, the module disconnects. Slide
the module slowly out of the cabinet.
