Effects of mounting surface and proximity
The proximity of the MicroFlex e150 to other
components could affect cooling efficiency. If the
MicroFlex e150 is mounted beside another
MicroFlex e150 (or other obstruction), there
should be a minimum space of 15 mm (0.6 in) to
maintain effective cooling.
If the MicroFlex e150 is mounted above or below
another MicroFlex e150 (or other obstruction),
there should be a minimum space of 90 mm
(3.5 in) to maintain effective cooling. Remember
that a MicroFlex e150 will be receiving air that has
been already heated if it is mounted above
another MicroFlex e150 or heat source. Multiple
MicroFlex e150 units mounted above each other
should be aligned, not offset, to promote air flow
across the heat sinks.
It is recommended to allow approximately 60 mm
(2.4 in) at the front to accommodate wiring and
connectors.
