3.5.5 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.

3.5.6 UPS output function

•

The 24 V DC connection at the UPS output is live even after a power failure. The maximum load

is 1.4 A.

•

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.
