Note the following points:
• Cooling can be attained either by a sufficiently large
backing plate (see Table 2.3) or by an additional cooler.
The cooler must be mounted centrally behind the
hottest area (1) of the device. See also “Project
planning notes, “Cold plate”” in Appendix A.3.
• The temperature on the rear panel of the drive
controller for highspeed drives must not exceed 85.0 °C. At a
temperature > 85 °C the device shuts down automatically. It can
only be restarted when it has cooled.
• Required evenness of contact surface = 0.05 mm, maximum
roughness of contact surface = roughness factor 6.3

Table 2.3 Required cooling with cold plate
Note the following points:
• The backing plate must be grounded over a large area.
• The best result for effective EMC installation is attained with a
chromated or galvanized backing plate. If backing plates are
varnished, the coating must be removed in the area of the contact
surface!
