Grounding Only One Point on the Net
In this manner of grounding, the shield is connected to ground only at the last device on the
net in the same way as described on
Pages 2-1
and
2-2
. Other devices of the net just pass the
shield. The use of a ferule to will allow the cable shielding to easily be inserted into the
terminal block.
1. Strip about 5 cm of the cable and cut off the gray cable shield. Remember to do this for
both bus cables (except for the last device).
2. Leave no more than 1 cm of the cable outside the terminal block and strip the data cable
at about 0.5 cm to fit in the terminals. See
Figure 2-5
.
Note:
Do this for both cables.

3. Fix both the cables on the frame with the clamp. See
Figure 2-5
.
