ONVENTIONS USED IN THIS BOOK
The
POWER+ SA
UPS is capable of operating with any of three possible line
configurations:
•
3-phase input – 3-phase output (abbreviated “3-3” )
•
3-phase input – 1-phase output (abbreviated “3-1”)
•
1-phase input – 1-phase output (abbreviated “1-1”).
The configuration used by the UPS depends on the AC input supplied and on the
UPS settings.
It follows that the UPS informational screens that display input and output voltages
and/or current will show data for one or three phases depending on the unit’s current
operating parameters. The figures below show the UPS Main screen displaying
output voltages in 3-phase and in 1-phase operation, respectively.
UPS Main screen with 3-phase output
UPS Main screen with 1-phase output
In this user manual, when illustrating a given UPS function that includes a voltage
display, both possible displays are usually not shown (the single-phase display and
the 3-phase display).
For simplicity’s sake, usually only one of the two possible displays is shown. The
reader is asked to remember that the number of phases displayed on the screeen of
his UPS depends on the UPS settings and the actual AC input.
