Losses and cooling data
Frame size R0 has natural convection cooling. Frame sizes R1…R4 are provided
with an internal fan. The air flow direction is from bottom to top.
The table below specifies the heat dissipation in the main circuit at nominal load and
in the control circuit with minimum load (I/O and panel not in use) and maximum load
(all digital inputs in the on state and the panel, fieldbus and fan in use). The total heat
dissipation is the sum of the heat dissipation in the main and control circuits.
