6.2 Shielding and grounding design
The supply voltage connection, as well as the signal and sense leads, must be
installed in such a way that electromagnetic interference does not adversely
affect module functionality (HBM recommendation: “Greenline shielding design”
– see
http://www.hbm.com/Greenline ). Always connect the cable shield by the
shortest possible length to the plug terminals and, as far as possible, lay the
shield flat at the control cabinet inlet with shield connection terminal blocks, e.g.
type SKS 8-SNS35 – 3062786 from Phoenix Contact – see illustration.

ample)
Double-shielded connecting cables, e.g. for sensors
We recommend using HBM cable Kab 7.5/00-2/2/2 wherever possible. The
cable is double-shielded and low in capacitance. When using double-shielded
cables, connect the outer shield only to the connection for the housing (ground
symbol , labeled “Outer cable shield” in the connection diagrams), not to one
of the GND connections ( ). In the case of control cabinets, also lay this shield
contacting on the cabinet – see illustration of shield clamp. Connect the inner
shields of the sensor cables to the connection labeled “Inner cable shield” (
).
Use the shortest lines possible for the connections.
Applications in areas with potentially explosive atmospheres are exceptions.
There connect
all cable shields to the potential equalization connection.
Single-shielded cables
Connect the shields of single-shielded cables to the connection for the housing
(ground symbol , labeled “Outer cable shield” or “Cable shield” in the connec-
tion diagrams), not to one of the GND connections ( ). In the case of control
cabinets, also lay this shield contacting on the cabinet – see illustration of shield
clamp.
