Uninterruptible Power Modules (UPM)
The eight-slot 9PXM chassis can accommodate a maximum of four power modules and the twelve-slot can
contain up to six modules. Each 4kVA has a built in 5 amp battery charger and is cooled by two cooling fans.
(see Figure 5 ). One power module (UPM) is able to fully charge five 9PXM battery strings ( 10 9PXM battery
modules).
NOTE You must install one 9PXM battery string (2 battery modules) in the main UPS chassis
for every power module present or the UPS will sound an “Not Enough Battery” alarm
indication.
