Module Replacement
Follow the instructions below when replacing or adding a system control, system monitor, power,
battery, or charger module. Contact your local Liebert representative if you need to purchase
additional modules to expand your system or contact authorized Liebert service representative for
replacement modules.
5.3.1
Removing Modules
1. Remove bezel cover to locate the faulty module. The yellow fault LED will be illuminated on the
faulty module.
2. The method for removing a module varies depending on the module type. The two methods are as
follows:
• When removing a
power, battery or charger module
, use a Phillips screwdriver to remove
the fastener (if installed). Then pull out the lock lever slightly and lift up to unlock the
module.
• When removing a
system control or system monitor module
, use a Phillips screwdriver
to remove the two screws from the securing holes on each end. Then pull out the lock lever
slightly and slide it to the left to unlock the module.
Figure 71 Lever and fastener
3. To pull out a power, charger or battery module:
a. When removing a power module, charger module or battery module: slide it 2/3 of the way out.
It will be stopped by the safety catch.
b. Lift the module up slightly while continuing to pull it out as shown in
Figure 72
.
c. Support the module and slide it completely out of the unit.
d. When removing a system control or a system monitor module, there is no safety catch because
the modules are lightweight.
NOTE
When removing bezels from a transformer-based UPS, note which have filters and replace
them accordingly. Bezels from the modules will have air filters. There will be no filters on the
bottom three transformer bezels. The transformer has a separate air filter.
For module removal, after unlocking the lever, wait a few seconds to remove the module.
If your system does not contain a redundant module, you may need to manually place the UPS
into manual bypass before removing modules to avoid accidental loss of output power for the
connected equipment.
