6.1 Glossary
Authorized voltage
Upper and lower voltage thresholds within which the UPS can operate
range for transfer to
on the automatic bypass in the event of a UPS fault or overload.
bypass if fault or overload
Automatic bypass
Automatic switch controlled by the UPS, used to connect the equipment
directly to the AC-power source.
Automatic start following
When AC input power returns following shutdown at the end of the battery
return of AC input power
backup time, UPS automatic start can be enabled or disabled.
Backup time
Time that the connected equipment can operate on battery power.
Bargraph
Device on the front panel indicating the percent remaining backup time
or the percent load.
Battery test
Internal UPS test on battery status.
Cold start
See "Start on battery power".
Connection module
Unit grouping the receptacles for connection to the AC-power source
and the equipment.
Dialog box
A window in a computer program displayed for selection by the user of various
options and parameter settings.
Double conversion
The power supplied to the connected equipment is completely regenerated
by continuous double conversion, i.e. the AC power from the AC-power source
is rectified (AC - DC), then converted back (DC - AC) to AC power.
Equipment
Devices or systems connected to the UPS output.
Forced shutdown
Ten-second interruption in the supply of power to the connected equipment
following a system shutdown, even if AC input power returns during
the interruption period.
Frequency-regulation rate
The rate at which the UPS frequency is synchronized with that
of the AC-power source. Two possible cases:
1. The installation comprises a single UPS. The frequency-regulation rate
is set to "Standard".
2. The installation comprises two UPSs connected in series. The AC-power
source supplies power to the first UPS which in turn supplies the second UPS.
The connected equipment is supplied by the second UPS.
The frequency regulation rate of the first UPS must be set to "Standard",
the frequency regulation rate of the second UPS must be set to "Redundancy".
