3.2 Installing the PN/MF Coupler
Necessary components
• PN/MF Coupler
• SIMATIC BusAdapter
• Strain relief for mechanical load of the PROFINET connections
• Mounting rail:
– Standard mounting rail (7.5 mm), or
– Standard mounting rail (15 mm)
You can find the article numbers for the components in the appendix Article numbers and
accessories (Page 130).
Installing the PN/MF Coupler on the standard mounting rail
1. Mount the standard mounting rail in such a way that sufficient space remains for installation
of and heat dissipation of the module (at least 10 mm on the left and 20 mm above the
module).
2. Hook the PN/MF Coupler into the standard mounting rail and swing it downward until you
can hear it latch into place on the standard mounting rail.
3. Plug the BusAdapters onto the PN/MF Coupler and screw them in place.
4. Connect the PN/MF Coupler as described in section Connecting (Page 27).
Note
Low resistance connection
If the standard mounting rail is mounted on a grounded metal plate or a grounded device
support plate, you must ensure a low-resistance connection between the standard
mounting rail and base. For example, on painted or anodized metals, use suitable
contacting agent or contact washers.
