Mounting Et 200Eco Pn M12-L On Non-Conductive Surface - Siemens SIMATIC ET 200eco PN M12-L System Manual

Connecting
4.4 Connecting ET 200eco PN M12-L to the functional earth
Mounting
Proceed as follows to connect ET 200eco PN M12-L distributed I/O devices to functional earth
with a conductive mounting surface:
1. Drill two fastening holes. The dimensions of the I/O device can be found in the section
Dimension drawing (Page 80).
2. Screw the module with the 5 mm fastening screws using a torque of 3 Nm.
Note
Earthing with conductive mounting substrate
If you attach a ET 200eco PN M12-L distributed I/O device to a conductive, grounded base,
the two fixing screws establish a conductive connection to the ground potential.
Ensure that there is a low-impedance connection between the I/O device and conductive
surface as well as between the conductive surface and the functional grounding.
Reference
You will find more information on installing the I/O devices in the section Mounting
(Page 18).
