8.4.3 Connecting the Signal-Line Shield
Two options for connecting the shield
You can connect the signal line shield to ground as follows:
• On the analog module by means of a shield-support element
(refer to the manual Hardware and Installation for the S7-300 or the manual
Distributed I/O device ET 200M in the section on wiring)
• Directly to the terminal block by means of a shielding plate
Connecting the shield to the terminal block using a shielding plate
1. Before mounting, attach a shielding plate to the terminal block.
2. Mount the terminal block on the DIN rail.
(In the figure below, you can see that the shielding plate is applied to the rear of
the terminal block and thus there is a connection to the grounded rail.)
3. Place the signal-line shield with the shield terminals on the shielding plate.
