Note
Cable assembly for connection to IE RJ45
interface
To connect the "X2 LAN2" interface (M12, 8
-pin) with an IE RJ45 interface, you need to
replace one of the M12 connectors of the cable "6XV1878
-5Gxxx" with the IE connector FC
RJ45 ("6GK1901
-1BB12-2AA0"). For strain relief to be guaranteed, you need to enlarge the
assembled cable to a length of approx. 5
- 10 cm behind the replaced connector using an
adhesive tape to Ø 8.
