surge suppressor as close to the ground as possible to minimize the length of the ground connection and use a single-point ground
system to avoid creating ground loops.

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 transients, noise, and ground plane
interference originating from devices or the environment. Contact Banner Engineering Corp. for more information.
Weatherproofing 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 connecting the antenna cable to the antenna or other cable and hand-tighten-
ing.
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.
Antenna Installation
Always install and properly ground a qualified surge suppressor when installing a remote antenna system. Remote antenna configura-
tions installed without surge suppressors invalidate the manufacturer's warranty.
