10.5.4 Grounding
NOTICE
Failure due to insufficient grounding
An optimum grounding is required to impede possible interferences from the
control and to discharge them to the ground.
Functional earth
Only the functional earth (FE) is used for the device. The functional earth is only used to dis-
charge disturbances. For individuals, the functional earth is not intended as protection against
electric shock.
The control is grounded via the top-hat rail. The top-hat rail, on which the control is mounted, has to be
mounted to a grounded metal carrier, e.
g. the rear panel of the control cabinet.
The control is provided with FE springs (metal clips) at its bottom side creating an electric connection
to the mounting rail while mounting.
If necessary, provide the top-hat rail with a separate grounding connection.
Potential equalization
Potential equalization acc. to DIN
VDE
0100 part 540 has to be provided between the system parts
and the voltage supply.
10.5.5 Shielding
NOTICE
Failure due to insufficient shielding
Provide sufficient shielding.
The shielding reduces any effects of interferences on the system.
Observe the following when shielding:
•
Fasten the shielding as extensively as possible
•
Ensure proper contact between connector and terminal
•
Avoid damaging or squeezing conductors
•
Note the wire specifications when connecting the shielding
•
Shield the closest possible to the signal terminal points
Route all power cables and data cables in separate cable channels.
