6.11 Setting the uninterruptible power supply
Introduction
UPS monitoring is an option you load as an add-on with ProSave.
A UPS ensures that the HMI device is shut down in a controlled manner after a buffer time in
the event of a power failure. This avoids the loss of data.
The following uninterruptible power supplies are supported:
SITOP DC UPS modules as of a rated power value of 6 A, e.g. 6EP1931-2DC42
Connect the UPS to the 24-V input and a USB port. Configure the USB port
for UPS monitoring.
Requirements
You have opened the "UPS Properties", dialog "Configuration" tab with the "UPS" icon.

Procedure
Proceed as follows:
1. If you want to enable battery mode, activate the "Battery mode" check box.
2. Enter the time for terminating applications in the "min" and "s" text boxes.
You will receive a message when UPS takes effect. Applications such as HMI Runtime
and WinAC MP are then terminated depending on the time entered.
3. If the port to which the UPS is connected is faulty and you therefore want to receive a
message, activate the "Port disturbed" check box.
4. Select the message you want from the list box.
5. Enter the time after which the "Faulty port" message is displayed in the "min" and
"s" text boxes.
