6.3 Module Replacement
Follow these instructions when replacing or adding a system-control, system-monitor, power, battery, or
charger module. Contact your Vertiv™ representative to purchase additional modules to expand your
system or for replacement modules.
6.3.1 Removing Power, Battery and Charger Modules
WARNING! Risk of heavy unit falling over. Can cause equipment damage, injury or death. Read
all of the instructions before attempting to move the unit, lift it, remove packaging or prepare
the unit for installation. The UPS presents 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.
1. Remove bezel cover to locate the faulty module. The yellow fault LED is 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 have air filters. There are no filters on the bottom three
transformer bezels. The transformer has a separate air filter.
NOTE: 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.
