Module Replacement; Removing Modules - Liebert Nfinity User Manual

Follow the instructions below when replacing a
control, battery, or power module, or when adding
modules to the system. To order additional
modules, contact your Liebert representative.

Removing Modules

1. Remove bezel cover of appropriate module.
When replacing a Power or Battery Module,
verify the faulty module by confirming the
amber LED is lit.
2. If removing a Control or Power Module with no
redundant modules, switch UPS to manual
bypass. Switch SW2 off (0) to minimize risk of
damage to modules.
3. Pull out and lift the lever if replacing a Control
or Power Module, then turn fastener
counterclockwise until it is loosened.
4. Start to pull out module. About 2/3 out it will
stop. Slide module away from the centre of the
UPS.
CAUTION:
Battery Modules are heavy—
30 kg (66 lb). Make sure to use two people when
removing a Battery Module. Continue to pull until
module is removed (seen at right).
5. Dispose of module in an environmentally
responsible way that complies with local
codes / regulations or return to Liebert for
proper disposal.
Note: Battery Modules may contain shipping
screws. These screws may be removed and
discarded.
