Installation
Location
CAUTION
This equipment is designed for operation in a
horizontal position only, with the mounting
brackets down. Do not operate in any other
manner.
Allow at least six inches (150 mm) of clearance around the
unit, to permit an unimpeded access of convection air cur-
rents for adequate heat dissipation. Place the attenuator to
permit the shortest possible cable length between the unit
and the transmitting equipment. Operate the attenuator in
a horizontal position only, with the handles on top.
Mounting
The attenuator may be used for portable operation or for
fixed installation, that is, it may stand free or be secured to
a bench or any convenient flat surface. For Models 8322,
8323 and 8325, the front and rear fins are made of heavier
gauge material bent outward 90• to form mounting flanges.
At each corner of these flanges is a _ inch hole. The holes
are arranged in a rectangle, see Specifications, Page 1-3,
and the fasteners must be placed throughout the bench and
the holes. Secure the screws in place with nuts and lock
washers. Model 8321 is equipped with rubber bumper feet
which can be removed for permanent mounting. The holes
are tapped for 8-32 screws. All models have a convenient
carrying handle nested among the cooling fins on the top
side.
