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 func-
tionality (HBM recommendation: "Greenline shielding design" – see
http://www.hbm.com/Greenline). Always connect the cable shield by the shortest pos-
sible length to the plug terminals and, as far as possible, lay the shield flat at the control
cabinet inlet with shield connection clamps, e.g. type SKS 8-SNS35 – 3062786 from
Phoenix Contact – see illustration of shield clamp.
Abb. 9: Shield clamp for flat contacting of cable shields (example)
If you want strain relief for the sensor cable, you can use the included shield connection
clamp ME-SAS MINI - 2200456 from PHOENIX. Then attach your cable to the clamp.
You can order more clamps from HBM by quoting 1-CON-A1023.
Important: For applications in areas with potentially explosive atmospheres,
connect all cable shields to the potential equalization connection.
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
"Outer cable shield" in the connection diagrams), not to one of the GND connections
( ). If you are using strain relief with a shield connection clamp, insert the rigid pin into
S
the connector for the outer cable shield (see figure below). Connect the inner shields of
the sensor cables to the connection labeled "Inner cable shield" (
