Section 2 Installation
2.3.1.1 Transmitter/Transformer Cabinet Positioning
Review the Outline Drawing to determine the size and placement of the transmitter at
your location. The transmitter and transformer should be located to permit adequate
maintenance access and sufficient ventilation.
!
CAUTION:
UNIT MUST NOT BE DROPPED. TWO PEOPLE ARE NEEDED TO REMOVE
THE CABINET FROM THE PALLETS, AND TO PLACE THE UNIT INTO A
CABINET OR WALL OPENING.
If the transmitter is to be positioned into a predetermined wall opening, be sure to allow
for any final leveling needed when figuring the wall opening dimensions.
NOTE:
The transformer can be located in the base of the rack in which the transmitter is
mounted, provided the rack meets access and ventilation requirements.
2.3.1.2 Rack Rails Installation
Locate the adjustable rack mount rails and install front to back, one on each side. Once
the location for the transmitter has been determined secure the rails using the provided
screws, with the wider flat weight-bearing portion facing up. Tighten all screws
including the length adjustment screws.
Carefully place the transmitter into the rack cabinet and secure with rack screws.
2.3.2 Air System And Cooling
Refer to the DAX-1/DAX-3 Cabinet Outline Drawing, for information on air flow
CFM, heat dissipation and duct work dimensions.
Cooling air for the transmitter enters through the back of the Cabinet and exhausts
through the front and top of the cabinet. If an exhaust duct is used, static pressure in the
duct must be neutral or slightly negative. Static pressure for air intake at the rear of the
transmitter must be neutral or slightly positive. The exhaust grills opening on the top of
the transmitter must not be restricted. This is an important consideration when a wall
will be installed along the front of the transmitter.
