8.2 Grounding
The rear panel on the INFRADUCER also has a connection for ground. The method of grounding depends on the method used
to mount the INFRADUCER.
1. If the INFRADUCER is mounted so that it is electrically insulated from the structure, connect the cable shield to the
ground terminal on the INFRADUCER and connect the other end of shield to ground at the power supply at the receiver
end.
2. If the INFRADUCER is mounted so that it is not insulated from the structure, do not connect the cable shield at the
INFRADUCER. Connect the cable shield only to ground near the power supply or receiver end. It is not necessary to
connect any wires to the INFRADUCER ground terminal.
