SFC4200/SFC1275G Synthesized Frequency Downconverter Installation
TM054 - Rev. 4.0 2-1
Section 2 - Installation
2.0 Installation Requirements
SFC Downconverters are designed to be installed within any standard 19 inch equipment cabinet
or rack, and requires 1 Rack Unit (RU) mounting space (1.75 inches) vertically and 19 inches of
depth. Including cabling, a minimum of 20 inches of rack depth is required. The rear panel is
designed to have power enter from the right and cabling enter from the center and left when
viewed from the rear of the unit. Data and control cabling can enter from either side. The unit
can be placed on a table or suitable stable surface if required.
Before initially applying power to the unit, it is a good idea to disconnect
the transmit output from the operating station equipment. This is
especially true if the current SFC Downconverter configuration settings are
unknown, where incorrect setting could disrupt existing communications
traffic.
2.1 Unpacking
The SFC Downconverter was carefully packaged to avoid damage and should arrive complete
with the following items for proper installation:
SFC Downconverter Unit
Power Cord, 6 foot with applicable AC Connector
Installation and Operation Manual
2.2 Removal and Assembly
Carefully unpack the unit and ensure that all of the above items are in the carton. If the Prime
AC power available at the installation site requires a different power cord/AC connector, then
arrangements to receive the proper device will be necessary before proceeding with the
installation.
SFC Downconverters are shipped fully assembled and do not require removal of the covers for
any purpose in installation. Should the AC Power Connector Cable be of the wrong type for the
installation, either the cable or the power connector end should be replaced. The power supply
itself is designed for universal application using from 100 to 240 VAC, 50 – 60 Hz.
2.3 Mounting Considerations
When mounted in an equipment rack, adequate ventilation must be provided. The ambient
temperature in the rack should be between 10
°
C and 35
°
C, and held constant for best equipment
operation. The air available to the rack should be clean and relatively dry.
2.4 Initial Power-Up
Turn the unit ‘ON’ by placing the rear panel switch (above the power entry connector) to the ‘ON’
position. Upon initial and subsequent power-ups, the SFC Downconverters will test themselves
and several of its components before beginning its main Monitor/Control program. These power-
up diagnostics show no results if successful. If a failure is detected, the Fault LED is illuminated.
