MD2401 L-Band Multi Demod Installation and Operation Manual Installation
MN-MD2401 2–2
Revision 7
IMPORTANT Should the AC power cable connector be of the wrong type for the installation, either
the cable or the power connector end should be replaced.
2.2 Installation Requirements
The MD2401 Demodulator is shipped fully assembled. It does not require removal of the covers
for any purpose in installation. Always insure that power is removed from the MD2401 before
removing or installing demodulators. The power supply itself is designed for universal application
using from 100 to 240 VAC, 50 to 60 Hz, 1.0A.
There are no user-serviceable parts or configuration settings located inside the
MD2401 chassis. There is a potential shock hazard internally at the power supply
module. DO NOT open the MD2401 chassis under any circumstances.
2.3 Mounting Considerations
The MD2401 can be installed within any standard 19 inch equipment cabinet or rack. The unit is
a two rack unit (RU) mounting space (3.5 inches) vertically and 15 inches of depth and requires a
minimum rack depth of 18 inches for cabling. The rear panel of the MD2401 is designed to have
power enter from the left and IF Cabling enter from the right when viewed from the rear of the
unit. Data and control cabling can enter from either side based on data interface option. The
unit can be placed on a table or suitable surface if required
When mounted in an equipment rack, adequate ventilation must be provided. The ambient
temperature in the rack should be between 10
° and 35° C, and held constant for best equipment
operation. The air available to the rack should be clean and relatively dry. The MD2401 units
may be stacked one on top of the other up to a maximum of 10 consecutive units before providing
one RU of space for airflow. Demodulator units should not be placed immediately above a high
heat or EMF generator to ensure the output signal integrity and proper receive operation.
Do not mount the MD2401 in an unprotected outdoor location where there is direct contact with
rain, snow, wind or sun. The MD2401 is designed for indoor applications only.
The only tools required for rack mounting the MD2401 is a set of four rack mounting screws and
an appropriate screwdriver. Rack mount brackets are an integral part of the cast front bezel of
the unit and are not removable.
Shielded cables with the shield terminated to the conductive backshells are required in order to
meet EMC directives. Cables with insulation flammability ratings of 94 VO or better are required
in order to meet low voltage directives.
IMPORTANT
The MD2401 CANNOT have rack slides mounted to the side of the chassis.
Two cooling fans are mounted on the right-hand side of the unit.
If the MD2401 is to be mounted in a rack, ensure that there is adequate
clearance for ventilation, particularly at the sides. In rack systems where there
is high heat dissipation, forced air cooling must be provided by top or bottom
mounted fans or blowers. Under no circumstance should the highest internal
rack temperature be allowed to exceed 50°C (122°F).
