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

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.
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-
