Grounding the device
For the functional earth (FE), there is a separate functional earth screw on
top of the device. The functional earth is electrically connected to the
circuit ground and the metal housing of the device.
Shielding ground
The overall shield of a connected shielded twisted pair cable is connected
to the grounding connector on the front panel as a conductor.
Beware of possible short circuits when connecting a cable section with
conductive shielding braiding.
Requirements for connecting electrical wires
Before connecting the electrical wires, always verify that the
requirements listed are complied with.
The following requirements apply without restrictions:
The electrical wires are voltage-free.
The cables used are permitted for the temperature range of the application case.
The voltage connected complies with the requirements for a safety extra-low voltage
(SELV) as per IEC/EN 60950-1.
Relevant for North America:
Exclusively use 60/75 °C (140/167 °F) or 75 °C (167 °F) copper (Cu) wire.
