The AM50/75 are designed to mount with the rear heat sink extended outside the customer-supplied enclosure. If the modules are mounted entirely inside the
customer supplied enclosure, the full power dissipation is inside the cabinet.

calculate cumulative system heat dissipation to ensure
that the ambient temperature inside the enclosure does
not exceed 50° C (122° F). To calculate total power
dissipation, add the dissipation of the system module to
the dissipation of the axis module(s).
