Module Replacement
Follow the instructions below when replacing or 
adding a Control, Battery or Power Module to the 
system.
To order additional modules, contact your Liebert 
representative or call 1-800-LIEBERT.
4.3.1 Removing Modules
1. Remove bezel cover of appropriate module. 
When replacing a Power or Battery Module, 
verify the faulty module by confirming the 
yellow LED is lit. 
2. If removing a Control or Power Module with 
no redundant modules, switch UPS to 
manual bypass.
3. Pull out and lift the lever if replacing a 
Control or Power Module, then turn fastener 
counterclockwise until it is loosened.
4. To remove the module:
a. Start to pull out module (shown above 
right, top). About 2/3 out it will stop. 
b. Slide module away from the center of the 
UPS (shown above right, center). 
c. Continue to pull until module is removed 
(shown above right, bottom).

responsible way that complies with local 
codes/regulations or return to Liebert for 
proper disposal.
