Setting the uninterruptible power supply

An uninterruptible power supply (UPS) ensures that the HMI device is shut down in a
controlled manner after a configurable buffer time in the event of a power failure. This avoids
the loss of data. Connect the UPS to the USB port of the HMI device. You can also configure
a message or the controlled shutdown of the HMI device when the UBS port is faulty.
SITOP DC UPS modules with a rated current of 6 A or more are supported as uninterruptible
power supplies.
Requirement
● The Control Panel is open.
● A UPS is connected to the 24 V DC connection and the USB port of the HMI device.
● The "Uninterruptable Power Supply (UPS) with USB support" option was transferred to
the HMI device with ProSave.
