Connecting the Equipotential Bonding Circuit
Procedure
Procedure:
1. Connect the grounding cable to the grounding terminal bolt on the rear of the HMI device.
2. Connect the grounding terminal bolt on the HMI device with the voltage bus of
2.8
Connecting the Power Supply
The plug-in terminal block for connecting the power supply is contained in the accessory kit
and is designed for cables with a maximum cross-section of 1.5 mm
CAUTION
Ensure safe electrical insulation of the power supply. Always use power supply modules
that conform to IEC 364-4-41 or HD 384.04.41 (VDE 0100, Part 410).
Only use power supplies that fulfill the standards SELV (Safety Extra Low Voltage) and
PELV (Protective Extra Low Voltage).
The power supply voltage must always be within the specified range to prevent
malfunctions on the HMI device.
Equipotential Bonding
Therefore, wire the 24 V output of the power supply to the equipotential circuit.
