Section 2 - Minimum Installation Requirements (E-Compact ATSC Transmitters) All the ferrous parts and accessories that make up the atmospheric discharge protection system must be hot galvanized or plated with a 254-mm coat of copper. The cable length from the lightning arrester up to the flowing pit cannot have any splices and the cable path must be such so as to avoid angles smaller than 90º, which could create sparking points. 2.3.
Section 2 - Minimum Installation Requirements (E-Compact ATSC Transmitters) 2.4.3 Cooling The air conditioning system should always be operated in the "recirculation" mode, with the room temperature being reduced without outside air coming in. For improved cooling system performance, the air conditioner should be installed in series with the transmitter's cooling cycle. I.e., the air conditioner's outgoing flow must be directed to the front part of Hitachi Kokusai Linear TV transmitter.
Section 3 - Installation (ATSC EC702HP Transmitter) Section 3 Installation 3.1 3 Introduction This section provides general information for planning the installation of the EC702HP transmitter, such as recommendations regarding Shelter, Tower, Antennas, Cables, Grounding, Power Line, Prevention against Transients, etc. 3.2 Inspection The package and the equipment must be inspected upon delivery in order to detect eventual visible damages.
Section 3 - Installation (ATSC EC702HP Transmitter) 3.3.2 Tower For the installation of the TV transmission and reception system, the tower must be made with hot-dip galvanized steel. A lightning protection system should be installed in the tower as well as nocturnal beacons bulbs with red glass. The following information about the tower must be obtained: (a) It must be provided of special insulator supports for descent of cordage of lightning rod, with a space of 1,5m maximum between them.
Section 3 - Installation (ATSC EC702HP Transmitter) Distance between the Rx and Tx Antennas They should be placed as far as possible from each other in order to isolate the transmitted signal from the received signal. Polarization It is very important to verify the polarization of the received signal, which can be vertical, horizontal or circular.
Section 3 - Installation (ATSC EC702HP Transmitter) 3.3.4 Equipment Installation Indoors Small equipments must be placed on a table in a way to provide easy access from all sides and be at least one meter far from the walls. Do not place anything on the top of the equipment in order not to compromise its natural ventilation. The ventilation system equipments must be placed directly on the shelter's floor as long as it is flat and they must be placed at least one meter far from the walls.
Section 3 - Installation (ATSC EC702HP Transmitter) 3.3.6 Electric Installation Grounding The shelter installations receive power through an aerial power line. Moreover, because of it, the lightning discharges that might hit the power lines generate power surges that can reach the shelter and consequently the equipments. To protect the equipments against eventual power surges, we recommend the use of gas filled surge protectors, after an isolation transformer with electrostatic shield.
