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.
It is also important that the data-lines are routed separate from power current carrying
cables if at all possible.
3.4 Connection - Notes
Mainly, the electrical characteristics are defined by the variable connection technique.
The connection can be made only in connection with the device specific pin
assignment!
At the delivery of the measuring system one device specific pin assignment in printed
form is enclosed and it can be downloaded afterwards from the page
„
www.tr-electronic.com/service/downloads/pin-assignments.html
”. The number of the
pin assignment is noted on the nameplate of the measuring system.
