overload
Automatic bypass Automatic switch controlled by the UPS, used to connect the equipment directly to the
AC-power source in the event of a UPS failure or an overload.
Automatic start following This function automatically starts the UPS when AC input power returns following
return of AC input power shutdown at the end of the battery backup time. It 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.
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.
Percent load Ratio between the power drawn by the connected equipment and the total power that
the UPS can supply.
Personalisation A number of UPS functions can be modified using the UPS Driver software to better
meet the user’s needs.
Programmable outlets Outlets that can be automatically shed during operation on battery power (a shedding
time delay may be programmed using Solution-Pac software.
Remote Power Off External dry contact can be used to stop the unit, during an emergency situation for
example. All power is removed from the load.
Start on battery power This function makes it possible to energise the connected equipment even when AC
input power is not available (operation exclusively on battery power).
UPS Uninterruptible Power Supply.
UPS ON / OFF via software It is possible to enable or disable use of UPS ON / OFF controls by the computer-
system protection software.
