REMOVAL
WARNING : Risk of heavy unit
falling over. Can cause equipment
damage, injury or death. Read all of the
instructions before attempting to move,
lift, remove packaging, or prepare the
unit for installation. The UPS represents
a tipping hazard.
Do not remove more than one module
at a time. Failure to do so may cause
unit to tip over and cause serious injury.
To locate a faulty module, remove the
bezel cover and look for an illuminated
yellow “fault” LED, which indicates a
faulty module.
If the removed bezel(s) have air filters,
replace them at this time.
NOTE : If your system does not contain
a redundant module, place the UPS into
manual bypass mode before removing
modules to prevent accidental loss of
power to the connected equipment.
1. Removing the
module‑securing bracket
Use a Phillips-head screwdriver to
remove the fastener (if installed).
2. Releasing the lock lever
Pull out the lock lever slightly and
lift up, then wait a few seconds
before continuing.
3. Removing the module
from the cabinet bay
Slide the module out about
two-thirds of the way until it is
stopped by the safety catch.
Lift the module slightly and, while
supporting the module, slide it
completely out.

4. Inserting a module
into a cabinet bay
Lift the module to the appropriate
bay, resting the end of the module
on the bay shelf.

be installed in the same row to
complete the battery string.
Slowly push the module in until
about one-third of the module is in
the bay.
Lift the module up, then continue
pushing until about 5 cm (2 in.) of
the module remains outside the bay,
then push it firmly and smoothly to
ensure that it is fully inserted.
5. Engaging the lock lever
Pull out the lock lever slightly
and press the lever down into the
bracket.
NOTE : If the lever does not press
down smoothly, remove and reinstall
the module.

module‑securing bracket
Use a #2 Phillips-head screwdriver
to install the module-securing
bracket.
