Using Shielded Cables
For many connections, we recommend shielded cable. Using shielded
cables and properly connecting their shields to ground protects
against electromagnetic noise interfering with signals transmitted
through the cables.
Within a cable, pairs of wires are twisted together. Using a twisted pair
for a signal and its return path provides further protection against
noise.
Shield wires should be terminated at one end only. The termination
panel is a convenient place to connect all shield wires while providing
the necessary ground connection.
ATTENTION
!
To avoid personal injury or equipment damage
caused by unpredictable axis motion in your system,
use shielded cable as directed in this manual.
