6.5.1. Adding/Reducing/Replacing Modules Online
N+X is the most reliable power supply conguration at present. N represents the minimum
number of modules of the UPS that the total load needs; X represents the number of the
redundant modules of the UPS, i.e. the number of the fault modules that the system can handle
simultaneously. The bigger X is, the higher the system reliability is. The 93PR can be installed
up to twenty modules in its cabinet and the N+X parallel redundancy system can be congured
as 1+ 9 or 9 +1 etc multiple di󰀨erent modes. The UPM modules can be added, reduced and
changed online and the quantity of the N and X of the N+X parallel redundancy system can be
changed according to requirement at any time. When the modules fail, if only the quantity of the
fault modules is less than or equal to X, the fault UPM modules can be changed online without
a󰀨ecting the UPS running.
Options Supplied by the N+X Parallel Redundancy System
The 93PR can be installed from 1 up to 10 UPS modules in its cabinet and the user can choose
the N+X parallel redundancy solution easily. Suppose the load is 80kVA and the optional solution
is listed in the following table:

Note:
• The “Permitted Maximum Power” does not mean that the UPS will be overloaded if this power value is exceeded.
For example, when selecting the 2+2 conguration, the rated UPS apparent power is 120(100)kVA and active
