Problem: Noise from a nearby fluorescent light or machine is interfering
with the communication of my FieldPoint Ethernet network module. How
do I suppress this noise?
Solution:
1.
Place a snap-on ferrite noise suppressor on the Ethernet cable. Install
the suppressor, using one half-turn (one pass-through) and place the
suppressor within 10 cm of the network module. You can purchase
a ferrite EMI suppressor from Fair-Rite Products (manufacturer part
number: 0443164251, available through the web site
h
ttp://www.fair-rite.com).
2. Install the entire FieldPoint bank in an EMC-rated enclosure or in
an earth-grounded cabinet. Shield all other I/O and control lines
connected to your FieldPoint Ethernet network module with EMC rated
cable raceway or metal conduit.
