Connecting the HMI device
Notice
An incorrectly dimensioned power supply can destroy the HMI device.
Use a DC power supply with adequate amperage; see Chapter 4. Technical Data
Notice
Safe electrical isolation
For the DC supply, use only power supply units with safe electrical isolation in accordance with IEC 60364-4-41 or HD
384.04.41 (VDE 0100, Part 410), e.g. conforming to the SELV/PELV standard.
The supply voltage must be within the specified voltage range. Otherwise, malfunctions at the HMI device cannot be
ruled out.
Applies to non-isolated system configurations:
Connect the GND connection from the DC power supply output to equipotential bonding for uniform reference potenti-
al. You should always select a central point of termination.
