CAUTION HEAT DISSIPATION AND ENCLOSURE POSITION
System and field power consumption by modules and termination assemblies is
dissipated as heat. You should consider this heat dissipation on the design and
positioning of your enclosure; e.g. enclosures exposed to continuous sunlight
will have a higher internal temperature that could affect the operating
temperature of the modules. Modules operating at the extremes of the
temperature band for a continuous period can have a reduced reliability.
