UPS output 
 
In order to maintain a screen display for the PC in the event of a power 
failure, the power supply unit is equipped with a UPS output for connecting 
a Control Panel. The maximum load for the output is 1.4 A (max. 2.5 A 
from 2016 and later). 
 
 
UPS output function 
 
•  The 27 V DC connection at the UPS output is live even after a power 
failure. The maximum load is 1.4 A (max. 2.5 A from 2016 and later). 
•  Once the PC has been de-energized via the UPS software, the UPS 
output is switched to 0 V. Any connected panel is thus switched off, 
and total discharge of the rechargeable battery is prevented.
