Out of tolerance The AC input source is either absent or its voltage or frequency is outside the
set limits.
Hot swap Connection module (with manual bypass) offering a socket for connection
to the AC-power source and outlets or a terminal block for connection
to the equipment.
Install Connection module (with manual bypass) offering terminal blocks
for connection to the AC-power source and the equipment.

to the AC-power source. Transfer of the load to the manual bypass enables
UPS maintenance or replacement, without interrupting the supply of power
to the connected equipment.
ON-LINE mode The normal UPS operating mode, by which the AC-power source supplies
the UPS, which in turn, following double conversion of the AC power,
supplies the connected equipment.
Percent load Ratio between the power drawn by the connected equipment and the total
power that the UPS can supply.
Personalization A number of UPS functions can be modified using the "UPS Driver" software
to better meet the user's needs.
Sleep mode This function shuts down the UPS after 5 minutes when it operates on
battery power and no load is detected on the UPS output. The UPS restarts
automatically as soon as the AC input source is restored.
Start on battery power This function makes it possible to energize the connected equipment even
when AC input power is not available (operation exclusively on battery power).
Tolerance for AC-power The range of frequency supplied by the AC-power source within which
source frequency the UPS can operate in ON-LINE mode (double conversion).
UPS Uninterruptible Power Supply.
UPS ON / OFF It is possible to enable or disable use of UPS ON / OFF controls
via software by the computer-system protection software.
