Chapter 2 Install the Dynamix 1444 Series Monitoring System
Temperature Considerations
While the 1444 series modules operate at rated temperature when mounted
vertically or horizontally, the system components have been designed for
cooling by natural convection based on a horizontal orientation. Therefore, to
make sure that there is optimal heat dissipation, the recommended mounting
orientation is horizontal (in an upright / vertical position) as shown in
Figure 1
.
Figure 1 - Module Mounting Position
The module plastics design enables natural convection or unducted airflow by
its ventilation slots on both sides of the module such to support a “chimney
effect” from bottom to top.
IMPORTANT Although the terminal base of expansion modules has a fully passive nature,
some electronics are present within the DYN module terminal base. Despite
low-power dissipation, the main terminal base is also equipped with
ventilation slots and some level of internal airflow ducting from bottom to
top. We recommend that you verify these ventilation slots are not blocked.
