5.3 Module Replacement
Follow the instructions below when replacing or adding a system control, system monitor, power, battery, or charger
module� Contact your local SolaHD representative if you need to purchase additional modules to expand your system or
contact authorized your Emerson representative for replacement modules�
5.3.1 Removing Modules
NOTICE
Risk of unintended shutdown� Can cause equipment damage�
Do not remove both the control and the monitor modules at the same time� Removing both the control module and
monitor module at the same time will cause the UPS to shut down and remove power from the load� Replace these
modules one at a time�
1. Remove bezel cover to locate the faulty module� The yellow fault LED will be illuminated on the faulty module�
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.
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�

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 71
�
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�
