Obvius A89DC-08 - Manual (Page 14)

Mechanical Drawings
The A89DC-08 must be mounted inside an appropriate enclosure rated for the weather, location, and electrical components
located inside it. The A89DC-08 mounting holes are detailed below.
Forced Air Cooling Application Note:
For use in high temperature environments, a fan may be required. The following drawing shows one example of forced air
cooling that can be used with the A89DC-08
The examples show use of a single fan and two fans. While airflow from a single fan is acceptable, two fans provides some
redundancy in case of mechanical failure. The fan should be capable of at least 10cfm. A thermostatic switch can also be
used to turn on the fan above specific temperatures.
The enclosure should include at least ½ cu ft of air volume per A89DC-08. For example, an A89DC-08 can be mounted in a
box that is 12” x 12” x 6” with one or two fans.
Recommended fan: NMB-MAT BG0703-B054 (24vdc, 0.2A), Ball bearing, 10cfm. [ Digikey.com p/n P12907-ND ]
