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.
Weatherproof Remote Antenna Installations
Seal the connections with rubber splicing tape and electrical tape to prevent water damage to the cable and connections.
Step 1: Verify both connections are clean and dry before
connecting the antenna cable to the antenna or other cable. Hand-
tighten the cable connections.
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
Antenna Installations. Install and properly ground a qualified surge suppressor when installing a remote antenna system. Remote
antenna configurations installed without surge suppressors invalidate the manufacturer's warranty. Keep the ground wire as short
as possible and make all ground connections to a single-point ground system to ensure no ground loops are created. No surge
suppressor can absorb all lightning strikes; do not touch the Sure Cross
®
device or any equipment connected to the Sure Cross
device during a thunderstorm.
