Page: 8 Model CA1250
Physical location and mounting
1. The CA1250 is convection cooled. That is, it depends on the natural free flow of air up through the slot perforations in the bottom
plate, over the internal heat dissipating fins, then out the top cover, for adequate cooling.
2. The CA1250 is designed for mounting into standard 19" (483mm) racks or on flat horizontal surfaces.
3. If mounted in an equipment cabinet or other confining location, allow at least 2 inches of space above the top cover (see Fig.
above). Be sure there are large openings in the shelf below the unit and in the cabinet to allow the entry of cool air and the
escape of warm air.
4. If the cabinet contains other heat generating components or you are using several CA1250’s, you will have to pay even closer
attention to adequate ventilation.
5. Do not hesitate to use fans (quiet, boxer type), if necessary, to ensure a constant flow of air through the CA1250's and the other
heat generating components.
6. When installing the CA1250 in a rack, please use racks that feature rear support provision. Adding a single RU (Rack Unit)
above and below the CA1250 will improve convection in heavy use applications. [One Rack Unit size = 1-3/4" (44.5mm) in
height].
7. In some installations, you may have large bundles of wire and cable to accommodate audio and speaker connections. Be sure to
allow enough room for the leads and dress them in such a manner so as not to block airflow.
