13. Uninterruptible power supply
With the optionally integrated UPS, the Automation PC 620 makes sure that the PC system
completes write operations even after a power failure occurs. When the UPS detects a power
failure, it switches to battery operation immediately without interruption. This means that all
running programs will be ended properly by the UPS software. This prevents the possibility of
inconsistent data (only functions if the UPC is already configured and the driver is activated).
By integrating the charging circuit in the Automation PC 620 housing, the installation has been
reduced to merely attaching the connection cable to the battery unit mounted next to the PC.
Special emphasis was placed on ease of maintenance when the battery unit was designed. The
batteries are easily accessible from the front and can be switched in just a few moments when
servicing.
Information:
More detailed information about uninterruptible power supplies can be found in the
UPS manual. This can be downloaded from the B&R homepage.
Information:
The monitor is not buffered by the UPS and will shut off when the power fails.
