Installation 2-1

SECTION 2: INSTALLATION

Introduction

This section contains information necessary to install the TW7000 in

its operating environment. Power, antenna, and accessory connections

are discussed. System diagrams are provided to show the proper con-

nections to a variety of accessories.

Type of Installation

The TW7000 can be installed in a variety of different ways. Proper

installation is particularly important in marine and vehicular installa-

tions; mounting and power source connections can make a difference

to transceiver performance.

Fixed Station

Unless otherwise specified when ordered, the TW7000 is shipped

ready for operation. The TW7000 uses an on-demand fan for cooling

the internal heat sink during periods of prolonged transmit operation.

Note: Supply adequate ventilation around the back of the TW7000 to

allow for proper air flow.

Vehicular or Marine

Mobile mounts should be used to mount the transceiver. On occasion

it may be necessary to fabricate special supplementary brackets to

complement a particular vehicle or shipboard location. DWC offers

rack, mobile, and shock mount kits for the TW7000, suitable for most

installations.

Input Power

Input power for the TW7000 is 13.8 Vdc, nominally, with a maximum

current requirement of 25A. The recommended operational voltage

range of the transceiver is 11 to 15.5 Vdc. The dc input connector

(12 Vdc input) on the back panel is a 2 pin, 25A circular receptacle

that has a square mounting flange with 2 male pins. The mating plug

is attached to the input dc power cable (C991829). This cable, sup-

plied with the TW7000, has a convenient connection to a variety of

+12 Vdc sources. For specific connections, refer to the Power Cabling

Accessories figure on page 2-10.
