Indoor Cabinets
This upright style cabinet has provisions in the base for bolting it down to a concrete floor.
All cabinets have an ac power outlet strip with six grounded outlets and a 4.5 meter (15
foot) CSA (UL) approved, three-wire line cord installed in the cabinet’s base. Remove the
knockouts that best fit your installation needs when routing the ac power cord, antenna
cable, and other wiring.
Caution
DOC and FCC Rules and Regulations require that the transmitter be installed so that
all controls are protected from adjustment by unauthorized personnel. Cabinet doors
must be kept locked unless the transmitter area is secure.
Transmitter Rack Mounting
When the Power Amplifier is ordered without a cabinet, it is supplied with rack mounting
hardware and can be installed in any standard EIA 19-inch rack. However, certain guide-
lines should be followed when installing the transmitter. The Power Amplifier location
should provide enough unobstructed space (at least 30cm [12 inches]) immediately to the
rear of the large finned heat sink and fan located on the rear of the PA chassis. This space
is necessary for proper cooling of the amplifier power elements.
When the Power Amplifier is installed in a cabinet, airflow through the cabinet should not be
restricted, and the cabinet should have ample louver openings for airflow at both top and
bottom.
5.3 Operating and Servicing Hazards
Voltages
Operating voltages ranging from a few volts to 120 or 240 volts ac are present in this
equipment. Care has been taken in the design of the equipment to insure personnel
safety. Terminals where ac line voltages are present are enclosed by covers that
require tools for removal. Do not remove these covers or service the equipment with
ac power applied to the equipment.
Human Exposure to Radio Frequency Energy
In August 1996 the Federal Communications Commission (FCC) of the United States with its
action in Report and Order FCC 96-326 adopted an updated safety standard for human exposure
to radio frequency (RF) electromagnetic energy emitted by FCC regulated transmitters. Those
guidelines are consistent with the safety standard previously set by both U.S. and international
standards bodies. The design of this product complies with the FCC guidelines and these
international standards.
This equipment is intended for use only in a permanent professionally installed licensed site.
Licensing of that site may require that an Environmental Assessment be performed based upon
human access, antenna type, antenna mounting height, ERP, operating frequency, duty factor,
and any co-located transmitters that contribute to the overall Radio Frequency energy exposure
level.
Compliance is ultimately the responsibility of the site licensee and a determination of compliance
can only be made by evaluating the complex factors of the specific site.
