REXROTH IndraDrive HCQ02 - Installation Conditions; Ambient and Operating Conditions

4.3 Installation Conditions
4.3.1 Ambient and Operating Conditions
Check that the ambient conditions, in particular the control cabi‐
net temperature, are complied with by calculating the heat levels
in the control cabinet. Afterwards, make the corresponding meas‐
urements to verify that the ambient conditions have actually been
complied with.
In the technical data of the individual components, the power dis‐
sipation is indicated as an important input value for calculating the
heat levels.
