DTC25U Operating and Service Manual

lll -- TRANSCODER INSTALLATION

To ensure long and reliable trouble-free service from the DTC25U transcoder the following steps

for installation are recommended:

MECHANICAL INSTALLATION: The DTC25U Transcoder was designed to be installed in a building

protected from the weather. The building should have a hard-surface floor such as concrete with a

moisture barrier. This barrier could be pressure-treated wood sub flooring which could be anchored

to the concrete and to the transmitter to make the installation earthquake resistant.

llow a minimum of three feet around the transmitter cabinet for service access. The top of the

transmitter should be clear for three feet above to allow the air to exhaust from the transmitter.

Provisions for air inlet and exhaust from the room must allow air flow with minimal obstruction.

In the event that the room temperature exceeds 35º Celsius (95º F), cooling air must be provided

so that the room temperature will not exceed 35 degrees Celsius under worse case conditions.

Notice: This equipment is HEAV

and must be handled by professional movers with prope

equipment. Any damage caused by the installers is not covered under warranty. Check to ensur

that installing crews have proper insurance coverage.

GROUNDING: Transmitter grounding is

ERY IMPORTANT and must be done correctly fo

safety and operational reasons. A typical installation may be done as follows

Use a heavy gauge wire such as 16 AWG stranded copper. The bonding between the transmitter

and the ground rods must be good quality and protected from corrosion. The ground wires should

run over the floor and be connected to the ground rods located outside the building. The wire

should not go thru the concrete floor but over and around it.

AC WIRING: The DTC25U transcoder comes with a three wire 110 VAC standard plug for

connection to a 110 VAC electrical outlet. It is recommended that the electrical outlet be protected

with its own separate breaker and used only for the transcoder.

NOTICE: All wiring of this type, except for the actual connection to the AC plug, must be done

by a QUALIFIED ELECTRICIAN and must conform to LOCAL and NATIONAL wiring CODES.

Consult with your electrician to ensure that the proper breaker size is selected for the main circuit.

ANTENNA CONNECTION: The transcoder is equipped with an N connector for output power to the

transmit antenna and an F connector for connection from the receive antenna.
