SECTION II
INSTALLATION
2-1.
INTRODUCTION.
2-2. This section contains information required for installation and preliminary checkout of the
Broadcast Electronics FM-5T/FM-5TS FM Transmitters.
2-3.
UNPACKING.
2-4. The equipment becomes the property of the customer when the equipment is delivered to
the carrier. Carefully unpack the transmitter. Perform a visual inspection to determine
that no apparent damage has been incurred during shipment. All shipping materials
should be retained until it is determined that the unit has not been damaged. Claims for
damaged equipment must be promptly filed with the carrier or the carrier may not accept
the claim.
2-5. The contents of the shipment should be as indicated on the packing list. If the contents are
incomplete, or if the unit is damaged electrically or mechanically, notify both the carrier
and Broadcast Electronics, Inc.
2-6.
ENVIRONMENTAL REQUIREMENTS.
2-7. Table 1-2 provides environmental conditions which must be considered prior to transmit
ter installation.
2-8.
COOLING AIR REQUIREMENTS.
2-9. If outside air is to be used to cool the transmitter, the air inlet duct must be sized to allow
adequate air flow. The air must be dry and well filtered. If intake louvers are used, opera
tion of the louvers must be electrically interlocked with the transmitter operation.
2-10. If the heated transmitter air is to be ducted from the room, the duct system must not intro
duce any back-pressure on the equipment. Proper allowances for air flow will ensure that
only a limited amount of heat is dissipated into the equipment interior. The duct system
must allow for a minimum air flow of 800 cubic feet of air per minute (22.6 m
3
/min).
2-11. As a minimum requirement, any duct work must have a cross-sectional area equal to the
exhaust area of the cabinet (refer to Figure 2-1). Sharp bends in the duct system will in
troduce back pressure and are not permissible. A radius bend must be used if a right angle
turn is required. An exhaust fan may be used to overcome duct losses or overcome wind
pressures if the duct is vented to the outside.
2-12.
INSTALLATION.
2-13. Each transmitter is wired, operated, tested and inspected at the factory prior to shipment
and is ready for installation when received. Prior to installation, this publication should be
studied to obtain an understanding of the operation, circuitry nomenclature, and installa
tion requirements. Installation is accomplished as follows: 1) placement, 2) component
installation, 3) remote control connections, 4) wiring, and 5) initial checkout.
2-14.
PRIMARY AC POWER.
2-15.
FM-5T.
The FM-5T transmitter is designed for operation from a closed-delta or wye con
nected three-phase source. Operation from an unsatisfactory power source will void the
warranty on this transmitter as any resultant damage is beyond the control of the manu
facturer. Before attempting installation of the transmitter, assure that the proper power
source is installed. Acceptable power input configurations are shown in Figure 2-2.
