6.2 Electromagnetic interference stability
A shielded data cable must be used to achieve high electromagnetic interference
stability. The shielding should be connected with low resistance to protective ground
using large shield clips
at both ends
. Only if the machine ground is heavily
contaminated with interference towards the control cabinet ground the shield should
be grounded
in the control cabinet only.
The applicable standards and guidelines are to be observed to insure safe and stable
operation!
In particular, the applicable EMC directive and the shielding and grounding guidelines
must be observed!
6.3 Connection
The pin assignment depends on the device type and is therefore noted at each
measuring system on the nameplate as pin assignment number. At the delivery of the
measuring system one device specific pin assignment in printed form is enclosed.
