UPS Principle
With the optional integrated UPS Interface Board, the Industrial Personal Computer
system completes write operations even after a power loss. When the UPS Interface
Board detects a power loss, it switches to battery operation immediately without
interruption. This means that all running programs are ended properly by the UPS
software. This prevents the possibility of inconsistent data.
NOTE:

This function is only available if the UPS is configured and its driver is activated
(see page 174) .

The monitor is not handled by the UPS and will shut off when the power fails.
