Power supply
CAUTION
Safe electrical isolation
Use only 24 VDC 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. to PELV standard.
The supply voltage must be within the specified voltage range. Otherwise, malfunction at
the HMI device cannot be ruled out.
Applies to non-isolated plant configurations:
Connect the connection for GND 24 V from the 24 V power supply output to equipotential
bonding for uniform reference potential. You should always select a central point of
termination.
The following table shows the permitted rated voltage and the corresponding tolerance
range.
