of the UPS are displayed using simple
universal technical symbols, instantly
communicating the overall status of the
UPS. The same screen also permanently

measurement, using three histograms
(one for each output phase). In the case
of the UPS not in normal functioning
mode, it is possible to access the
“Warning and Alarm” summary page
directly from the default page. Warnings
and alarms shall be identified by text
strings and codes. In battery operation,
the display shall switch between warning
code and estimated backup time in
minutes.
After 30 seconds of inactivity (i.e. without
buttons being pressed) the display
reverts to the default page.
The text displayed by the LCD shall be
available in English, Italian, French,
German, Spanish Portuguese, Turkish
and Chinese, selectable by the user.
