COAXTRAB Surge Voltage

Protection Adapter CN-UB-280DC

1. Introduction

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 an-

tenna cables.

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.

The CN-UB-280DC features a gas-filled discharge ar-

rester between the inner and outer conductor. See

Figure 2.

Figure 2. CN-UB-280DC Schematic Diagram

The gas discharge tube can be replaced in the event

that a direct lightning strike causes a failure. See

Figure 3.

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.

4. Typical Cabinet Installation

Figure 8 shows a typical CN-UB-280DC installation in-

side a cabinet. To avoid problems, please observe

the following guidelines when installing the CN-UB-

280DC 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 single-

point earth ground.

• Avoid loops in grounding wire.

• Avoid making sharp bends in wire.

General Specifications

Note

The threaded cap contains a recess that

positions the gas arrester tube in the center

of the access hole. If the gas arrester tube

is not positioned in this recess while installing

the threaded cap, the arrester will not seat

properly and the threaded cap will not screw

completely into the housing.

If you experience a problem installing the

gas arrester tube, remove the COAXTRAB

adapter from the system. Then position the

adapter as shown in Figure 13 and install

the gas arrester tube.

2. Insert the replacement gas arrester tube in the

recess of the threaded cap. Then carefully

insert the gas arrester tube and cap into the

access hole of the adapter and tighten the cap.
