Pin assignment for the analog electronic modules
Using the shield support
To prevent interference we recommend the following for analog electronic modules:
● Use pre-fabricated shielded cables to the connection modules.
● If you are fabricating your own cable, place the cable shield on the ferrous connector
enclosure or use terminal 5 for shield support purposes.
The connection module connects the cable shield with low impedance to the main ground
line.
