III. TRANSMITTER INSTALLATION
To ensure long and reliable trouble-free service from the DTXPRO-1.2KU transmitter the
following steps for installation are recommended:
1. MECHANICAL INSTALLATION: The DTXPRO-1.2KU 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. 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 flow thru the transmitter is approximately 2,000
CFM. 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 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 the installing crews have proper insurance coverage.
2. GROUNDING: Transmitter grounding is VERY IMPORTANT and must be done correctly
for safety and operational reasons. The single point grounding technique can be effective
to protect multiple pieces of equipment installed inside an equipment rack cabinet. Treat
the rack the same as you would a building, a copper bus bar has been mounted inside the
cabinet to act as both an entrance panel and reference ground for all conductors entering
and leaving the rack. It is recommended the customer install an AC surge protector at this
point in shunt to ground, and install a series impedance between the panel and the
equipment. The chassis of each piece of equipment has been bonded to this buss bar with
a single copper braid or strap. Redundant ground connections by means of the AC cable
and the shields of audio cables should be avoided when possible. Finally, connect the
rack’s access panel to the building reference ground using a heavy gauge wire such as #2
AWG stranded 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 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.
3. AC WIRING: Wiring to the house electrical sub-panel will use the supplied 4-wire cable
already connected to the ACDIS2 Panel inside the transmitter cabinet. Connections to the
AC Main should be made as follows:
--- RED and BLACK are connected to the 220 VAC.
--- WHITE WIRE is connected to NEUTRAL.
---GREEN WIRE is connected to 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.
