III — TRANSMITTER INSTALLATION
To ensure long and reliable trouble-free service from the UTX3KW-A transmitter the following steps for
installation are recommended.
1. MECHANICAL INSTALLATION: The UTX3KW-A was designed to be installed in a building
protected from the weather. The building should have a hard-surface oor such as concrete with a
moisture barrier. This barrier could be pressure-treated wood sub ooring which could be anchored
to the concrete and to the transmitter to make the installation earth quake resistant.
Allow 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.
Air ow thru the transmitter is approximately 2500 CFM. Provisions for air inlet and exhaust from
the room must allow air ow with minimal obstruction. In the event that the room temperature
exceeds 35 degrees Celsius, cooling air must be provided so that the room temperature will not
exceed 35 degrees Celsius under worse case conditions.
Notice: This equipment is HEAVY and must be handled by professional movers with proper
equipment. Any damage caused by the installers is not covered under warranty. Check to ensure that
installing crews have proper insurance coverage.
2. GROUNDING: Transmitter grounding is VERY IMPORTANT and must be done correctly for
safety and operational reasons. A typical installation may be done as follows:
Use a heavy gauge wire such as #2 AWG strained copper or solid copper buss one (1) inch wide
by 1/8 inch thick for connections. The bonding between the transmitter and the ground rods must
be good quality and protected from corrosion. The ground wires should run over the oor and
connected to the ground rods located outside the building. The wire should not go thru the concrete
oor but over and around it.
3. AC WIRING: A ten (10) foot cable has been provided with the transmitter to facilitate the
connection to the AC Main power source.
Connections to the AC Main should be made as follows:
— RED, BLACK, AND ORANGE are connected to the 208 VAC 3-PHASE terminals
— WHITE WIRE is connected to the NEUTRAL terminal
— GREEN WIRE is connected to the SAFETY GROUND
NOTICE: All wiring of this type 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.
4. ANTENNA CONNECTION: The transmitter is equipped with 1 5/8 EIA Flange connector located
at the top of the rack. Conditions vary from site to site so some engineering may be required to
ensure that the antenna is receiving the correct amount of power to comply with FCC licenses and
to ensure safety from lighting etc.
