GENERAL INFORMATION AND INSTALLATION 1 GENERAL INFORMATION One of the keys to a successful installation is meticulous planning and adequate allowances for task times. Allow sufficient time to consider and plan all aspects of the installation, including the building, whether new or existing. Once determined allow for realistic time spans for the building construction or renovation, equipment transportation and installation, and final commissioning.

GENERAL INFORMATION AND INSTALLATION 2 GROUNDING/EARTHING For safety, it is important that grounding conductors of adequate size be used to connect the transmitter (and other) cabinet(s) to the station "technical ground" point. The following notes are supplied as a guide to grounding at fullservice transmitter installations but are useful for all cases.

GENERAL INFORMATION AND INSTALLATION Although most audio and video signals around the transmitter plant are of relatively high levels, it is well to be aware of another planning aspect; this is the possibility of inadvertent creation of one or more "ground loops" of the kind that can induce hum into low level audio circuits.

GENERAL INFORMATION AND INSTALLATION 3 LIGHTNING AND OTHER TRANSIENT PROTECTION The real-world environment of transmitting equipment is one where periodic lightning storms may occur and cause antenna, tower, and power line strikes. The actual incidence varies widely with geographic location and is also affected by local topography, the height of the tower, and routing of the incoming power and telephone lines.

GENERAL INFORMATION AND INSTALLATION 4 ABOUT POWER WIRING The DTR10SC transmitter requires a single phase power source. Typical measured power consumption of the amplifier unit at full power is 150W. The standard design allows the transmitter to operate line-to-neutral from single phase 100 to 130V. For standard line-to-neutral operation, a single fuse is employed for circuit protection of the DTR10SC. Because the transmitter uses a switching power supply, the fuse specified is fast blow 5 Amps.

GENERAL INFORMATION AND INSTALLATION 5 VENTILATION/AIR CONDITIONING INFORMATION At full power, the maximum amount of heat is generated by the RF amplifier. This heat is removed by natural convection mostly through the heatsink on the front of the unit and partially through the amplifier’s enclosure. Care must be taken when locating the DTR10SC amplifier that there is nothing impeding air flow around the heatsink.

GENERAL INFORMATION AND INSTALLATION 6 FIRE PROTECTION Planning fire protection is important in installations where electrical and electronic equipment exist. Systems may be needed to shut down other air systems in the building, to close air dampers and fire doors, and to enable activation of automatic firefighting apparatus, if provided. Automatic methods should be made available for reporting of the fire through the remote control.

GENERAL INFORMATION AND INSTALLATION 7 UNPACKING Carefully inspect each package as it is received, for possible shipping damage. Claims for damaged equipment must be filed with the carrier within seven days of delivery or the claims will not be accepted. Unless specific contractual arrangements for title, FOB location, etc. have been made, generally the delivery of the equipment to the carrier by LARCAN INC.

GENERAL INFORMATION AND INSTALLATION 8 FIRST-TIME, ON-SITE TRANSMITTER START-UP PROCEDURE The DTR10SC transmitter’s power meter is calibrated in the factory for 100% at full power at the channel specified when the unit is tested. The DTR10SC, as delivered, is also tested with the accompanying HCS-5000R+ transcoder so that the transcoder RF output level is already set to the correct level to achieve 100% power when the system is correctly installed and powered.
