Surge suppressors should be properly grounded and mounted at ground level near where the cabling enters a building. In-
stall the surge suppressor indoors or inside a weatherproof enclosure to minimize corrosion or component deterioration.
For best results, mount the surge suppressor as close to the ground as possible to minimize the length of the ground con-
nection and use a single-point ground system to avoid creating ground loops.
For more detailed information about how antennas work and how to install them, refer to Antenna Basics (p/n 132113)
(also included as a chapter within the product manual).

I/O Isolation. When connecting analog and discrete I/O to external equipment such as VFDs (Variable Frequency
Drives), it may be appropriate to install interposing relays and/or loop isolation devices to protect the DX80 unit from tran-
sients, noise, and ground plane interference originating from devices or the environment. Contact Banner Engineering
Corp. for more information.
4.4.1 Weatherproof Remote Antenna Installations
Prevent water damage to the cable and connections by sealing the connections with rubber splicing tape and electrical
tape.
Step 1: Verify both connections are clean and dry before con-
necting the antenna cable to the antenna or other cable and
hand-tightening.
Step 2: Tightly wrap the entire connection with rubber splicing
tape. Begin wrapping the rubber splicing tape one inch away
from the connection and continue wrapping until you are one
inch past the other end of the connection. Each new round of
tape should overlap about half the previous round.
Step 3: Protect the rubber splicing tape from UV damage by
tightly wrapping electrical tape on top of the rubber splicing
tape. The electrical tape should completely cover the rubber
splicing tape and overlap the rubber tape by one inch on each
side of the connection.
