•
Connect all inactive metal parts (doors and housing of the control cabinet, DIN
mounting rails, etc.) to the ground potential.
•
Always connect the cable shielding to the ground connection across a large area
at both ends.
•
Use suitable cable clamps to connect the shielding of the shielded cables to the
ground potential directly at the access to the system (control cabinet, frame, DIN
mounting rail). The cable clamps must reach all the way around the cable shield‐
ing.
•
Use suitable cable clamps to connect the cable shielding to the ground potential,
once again as close as possible to the main module (e.g., on the DIN mounting
rail). The cable clamps must reach all the way around the cable shielding.
•
Keep the cable ends from which the insulation has been stripped as short as pos‐
sible.
•
Insulate the end of the shielding braid, for example using a suitable heat-shrink‐
able sleeve.

Preparing the electrical installation
To carry out the electrical installation, you will need:
•
Connection cables for the peripheral devices, including the corresponding data
sheets
•
Voltage supply cable
•
If customers assemble the cables: crimping tool, ferrules, soldering iron, and other
installation material
