6.1 Glossary
Authorized voltage
The range of voltage supplied by the AC-power source within which the UPS
range for operation in ECO
can operate in ECO mode. In ECO mode, the equipment connected to the
in ECO mode
UPS is supplied directly by the AC-power source, via the automatic bypass.
Authorized voltage
Upper and lower voltage thresholds within which the UPS can operate
range for transfer to
on theautomatic 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.
CLA (Long backup-
Module incorporating a charger for long backup times. The charger is powerful
time charger)
enough to charge battery extension modules offering very long backup times.
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.
ECO mode
Operating mode by which the equipment is supplied directly by the AC-power
source if it is within the tolerances defined by the user. This mode reduces
the consumption of electrical power.
Equipment
Devices or systems connected to the UPS output.
Fault tolerant
Connection module (without manual bypass) offering receptacles
for connection to the AC-power source and the equipment.
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.
