Description
N+1
Parallel redundant
operation
* Parallel redundant operation system: where there is surplus
of one unit from UPS units in parallel connection to handle
load capacity
None
Single /
parallel operation
* Single operation system: where there is one UPS unit
* Parallel operation system: where total capacity of UPS units
in parallel connection is used as connectable load capacity in
operation
If “
N+1
” is selected, when there is no surplus of one UPS unit for load capacity connected to UPS,
the LCD screen displays “
FT Disabled
”. In this case, reduce the load connected to UPS.
However, the load factor value “
LF = %
” displayed by viewing UPS measurements is same even when
either setting value (“
N+1”
or
“
None
”) is set. See §8 “Notes on UPS Measurements Information” for
details.
