Replacing Modules; Replacing The User Interface - Liebert Nfinity User Manual

Replacing Modules

Note: Power Modules must be installed in a bay
in the top half of the Nfinity frame. Battery
Modules can be installed in any bay of the UPS
frame.
1. Lift module to appropriate bay, resting end of
module on bay shelf. Use caution not to rest
the module on the lower bezel cover.
2. Push module into bay. Once halfway in, slide
module sideways toward the centre of the
UPS. Continue pushing module until fully
inserted.
3. Press and turn fastener clockwise until locked.
If replacing a Control or Power Module, press
lever down.
4. Wait about 30 seconds as the module
performs a start-up test and synchronizes with
the other modules. Both the amber and green
LEDs should be flashing. A green flashing
LED will then confirm the module is properly
connected.
5. If UPS was placed in bypass manually,
transfer back to UPS operation.
6. Replace bezels.
Note: When replacing the Control Module,
record user configuration data before removing.
Re-verify the configuration settings after the
new Control Module is installed.
Replacing the User
Interface
1. Lift off user interface and set it on top of the
UPS frame.
2. The attached cable will be connected to an
Intellislot card, found in a port between the
control modules.
3. Disconnect the cable from the Intellislot card.
4. Install the new Intellislot card in the UPS.
5. Plug the new user interface cable into the
Intellislot card.
6. Set replacement User Interface into proper
position.
