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.

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.
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
Allows a "clean" of computer operating systems depending on the low battery
threshold setting. If the input source is restored during the time period
between the shutdown order and actual system shutdown, it causes a
voluntary interruption of the supply of power to the connected equipment
(lasting 10 seconds) after system shutdown.
