UPS: OFFICE 400 - 2000
Operation and Service
OFFICE Series
32
The autonomous mode is supported by an
acoustic beeping of about a 1 second duration
and an 8 second pause.
The UPS output remains switched on, the loads will continue to be supplied for
the duration of the autonomy time.
The charging of the accumulator can be ob-
served. For this, the appropriate display page
must be selected (TOUCH) so the information
shown here can appear.
Generally, a low battery level can also be recognized by a blinking battery sym-
bol. An acoustic beeping of a roughly one second duration and 1 second pause
signalizes when the autonomous mode is about to end.

Switching off the UPS
Switching off occurs by means of activating
the on/off switch again. The device switches
the UPS outlet on whereby the charging unit
remains. The display changed to the image
pictured here.
In the event of a complete shutdown of the device, the UPS must also be sepa-
rated from the mains power supply.
6.1.6
Direct switching on of the autonomous mode (COLD START)
Without the power connection, the UPS is
switched on and started by activating the on-
off switch and changes directly to the
autono-
mous mode
. The display shows the screen
pictured here.
The starting process is supported here by a
sustained beep (3-4 s).
The UPS output is switched on, and the loads are supplied for the duration of
the autonomy time. After re-activating the on-off switch, the UPS shuts down
completely again.
This operation mode is frequently used to determine the remaining autonomy
duration.
