2.0 INSTALLATION
2.1 Unpacking the Unit
Carefully remove the equipment from its packing material and set it on a solid surface, such as a table or
desk. If it appears damaged in any way, notify the carrier, and keep all packing materials for inspection by the
carrier’s agent.
2.2 Operating Environment
The MA4001B chassis includes an active cooling fan tray which forces cooling air from the bottom through to
the top of the chassis. (See options (p 8) for selection of front air intake – rear air intake is factory default). For
adequate ventilation, a space of 1U (1.75”) should be left in the rack, directly above the MA4001B chassis for
warm air exhaust. It is designed to operate at temperatures ranging from 10 to 40
o
C (50 to 104
o
F). As with all
electrical equipment, operation at excessive temperature accelerates the deterioration of components. For this
reason, measures should be taken to prevent the build up of excessive heat in the rack.
2.2.2 Antenna Requirements
The MA4070B is used with a user-supplied antenna. Please consult table 2.2A for further information. Mount
the antenna according to the manufacturer’s instructions.

A self-adhesive RF exposure label is supplied with each MA4070B unit for the user to affix to their antenna.
To operate the MA4070B in compliance with FCC regulations, you must apply the included label on to the
antenna. Peel off the protective backing from the label and affix it to the front of the antenna such that the
label is readable from a distance of 3 feet.
☛
Caution: To comply with FCC RF exposure regulations in section 1.1307, a minimum
seperation distance of 1.5 meters is required between this antenna and all persons.
2.3 Power Requirements
The equipment has an international auto-ranging internal power supply which allows it to be powered from any
100 to 240 VAC; 50 to 60 Hz source.
Check the total current consumption of all equipment on the same line before applying power to the MA4000B
system. Avoid sharing an AC source that feeds heavy motors or other equipment, which require large current
drains.
2.4 Rack Mounting
The MA4000 system is designed for standard rack mounting in a 19” equipment rack. It requires 4U (7.00”) of
vertical rack space. It should be installed in a rack allowing access to the back of the unit. The upconverter
should be isolated from strong RF radiation emanating from local equipment in the rack. Power line transients
that may cause damage to the unit should be avoided.
