INSPIRING INNOVATIONS COAXTRAB Surge Voltage Protection Adapter CN-UB-280DC For wireless data, signal and mobile phone system protection Installation Instructions 2098A June 2005 1. Introduction The gas discharge tube can be replaced in the event that a direct lightning strike causes a failure. See Figure 3. The Phoenix Contact COAXTRAB CN-UB-280DC (see Figure 1) is a gas-filled surge protection device designed to protect wireless radio and module phone base stations from surge voltages caused by lightning or other electrical sources that are induced onto antenna cables. COAXTRAB Surge Voltage Protection Adapter Gas Arrester Tube Access Hole Gas Arrester Tube PN 2818203 The CN-UB-280DC is available in two configurations; one with N-type male/female connectors and the other with N-type female/female connectors.

CN-UB-280DC Gas Discharge Arrester The CN-UB-280DC has a separate ground terminal for installations where nonmetallic enclosures are used or where a reliable grounding surface is not present. See Figure 4. CAUTION Always keep the ground wire as short as possible and, when possible, make all ground connections to a single common point. Without a single-point ground system, lightning becomes a critical concern for base stations. The single-point ground insures that no ground loops are created. 2098A003 Female N-type Connection Female N-type Connection Figure 1. CN-UB-280DC Configurations The CN-UB-280DC features a gas-filled discharge arrester between the inner and outer conductor. See Figure 2.

Typical Cabinet Installation Figure 8 shows a typical CN-UB-280DC installation inside a cabinet. To avoid problems, please observe the following guidelines when installing the CN-UB280DC adapter. * * * * * * * Install adapter as close as possible to the radio. Ensure cabinet is properly grounded to earth. Make sure adapter is grounded to cabinet. If necessary, install separate ground wire. Always make ground wire as short as possible. When possible, connect ground wire to singlepoint earth ground. Avoid loops in grounding wire. Avoid making sharp bends in wire.
