RISK OF ELECTRIC SHOCK

TO REDUCE THE RISK OF ELECTRIC SHOCK,

CAUTION:

DO NOT REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE.

REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

Caution

These servicing instructions are for use by qualified personnel only. To reduce the risk of electrical shock, do not perform any servicing other than that contained in the Installation and Troubleshooting Instructions unless you are qualified to do so. Refer all servicing to qualified service personnel.

Special Symbols That Might Appear on the Equipment

This symbol indicates that dangerous voltage levels are present within the equipment. These voltages are not insulated and may be of sufficient strength to cause serious bodily injury when touched. The symbol may also appear on schematics.

The exclamation point, within an equilateral triangle, is intended to alert the user to the presence of important installation, servicing, and operating instructions in the documents accompanying the equipment.

For continued protection against fire, replace all fuses only with fuses having the same electrical ratings marked at the location of the fuse.

Electrostatic discharge (ESD) can damage the BT100 unit and circuit card assemblies. Wear an antistatic wrist strap attached to a chassis ground to prevent ESD damage.

This equipment operates over the marked Voltage and Frequency range without requiring manual setting of any selector switches. Different types of line cord sets may be used for connections to the mains supply circuit and should comply with the electrical code requirements of the country of use.

It is recommended that the customer install an AC surge arrestor in the AC outlet to which this device is connected. This is to avoid damaging the equipment by local lightning strikes and other electrical surges.

BT100 Installation and Operation Manual

Section 2

Overview

The BT100 is a three or four output, two-way capable amplifier used in Cable Access Television (CATV) distribution systems. All models are high gain, three-stage hybrid amplifiers designed to drive both a cascade and a local distribution system. The BT100 is powered by the 60/90 VAC cable supply and can be configured to pass this power to additional amplifiers and line extenders. Installation of the return path enables two-way signal flow.

The standard model BT100 includes an amplifier electronics module with an integrated power supply, which is furnished complete in the model BT*-100*/15 housing, as shown in Figure 2-1. You may also purchase the electronics module only with no housing.

Ordering Guide

Several models of the BT100 are available. The BT100 is fully configured in the factory per model requested. You can find the model name on labels on the outside of the shipping carton, the side of the BT100 housing, and the side of the electronics module.

Figure 2-3 identifies and describes the model strings.

2-4 Overview

Housing

The BT100 RF amplifier and DC power-supply circuitry are integrated into a single electronics chassis that is furnished in the BT*-100*/15 housing. The housing protects the electronics from weather and dissipates internally generated heat.

Figure 2-4 illustrates the top view of the BT*-100*/15 housing and provides its dimensions.

BT100 Installation and Operation Manual

Overview 2-5

Coaxial cable connections to the housing are made using conventional 5/8 inch x 24 threads per-inch stinger-type connectors. Seven port plugs in the cover enable access to internal test points without opening the housing.

Two messenger clamps are attached to the side of the housing (Figures 2-5, 2-7) and are secured with 5/16 inch x 24 threads-per-inch stainless-steel bolts for strand (aerial) mounting. The bottom of the housing also contains two 5/16 inch x 24 threaded holes located on the horizontal center-line separated by eleven inches center-to-center (Figure 2-7). Use these holes and the bolts from the messenger clamps for pedestal and surface-mounting installations.
