Site and Shelter Requirements
The Model 8329-300 Attenuator should be operated in a dry, dust, and vibration free environment.
The ambient temperature range should remain between -40°C and +45°C (-40°F and +113°F) for proper operation.
Allow at least 12" (300mm) of clearance around the unit, 6" (150mm) if it is equipped with a blower, to permit
unimpeded access of convection air currents for adequate heat dissipation.
Place the attenuator as close as possible to the transmitting equipment, to permit the shortest possible cable
length.
Tools Required
The following tools and supplies will be required to prepare the unit for use.
Wrenches
Standard screwdrivers
9/16 Hex wrench (for thermoswitch installation)
Pipe sealing compound (for thermoswitch installation)
Soldering Iron and solder (for thermoswitch installation)
Bolt and nut sets or lag screws (for mounting)
Mounting
The attenuator may stand free, may be secured to a bench, or any convenient flat surface. The front and rear face
plates are made of heavier gauge material bent outward 90° at the bottom to form mounting flanges. At each
corner of these flanges is a 3/8 inch hole for use with suitable fasteners up to 3/8 inch. The holes are arranged in a
20-23/32 inch x 4-1/2 inch rectangle (526.3 x 114.3mm). The front and rear face plates of the attenuator are also
bent over on the top to form convenient carrying handles.
1.
Place the unit on a flat surface.
2.
Insert the fasteners, up to 3/8 inch, through the bench and the holes.
3.
Secure the bolts with nuts and lock washers.
CAUTION
This equipment is designed for operation in a horizontal position only, with mounting
brackets down. Do not operate in any other manner!
