Mechanical Information
Model 743 and Model 744 VME Board Computers
Air Flow Requirements
The air flow requirements for the Model 743 and Model 744 are as follows:
46 linear meters (150 linear feet) per minute, -5 Deg C to 35 Deg C (23 Deg F to 95 Deg F)
61 linear meters (200 linear feet) per minute, 35 Deg C to 55 Deg C (95 Deg F to 151 Deg F)
NOTE:
Model 743 and Model 744 VME Board Computers are to be operated only in an environment
that is free from conductive pollution, including dry non-conductive pollution which could
become conductive due to expected condensation.
CAUTION:
Integrated circuit case and junction temperatures must not exceed those shown in
Figure 4-3 and Figure 4-4.
