5.4.3 Mounting in ”cold plate” technique
When using ”cold plate” technique the controllers can be mounted to sum
coolers. Use controllers of type E82CV... .
The following points are important to ensure a safe operation of the drive
controllers:
l Good thermal contact with the cooler:
– The contact area between the cooler and the drive controller must be at
least as large as the cooling plate of the drive controller.
– Plane contact area, deviation max. to 0.05 mm.
– The cooler and heatsink must be attached using all the screwed joints
that are specified.
l Thermal resistance R
th
according to table. The values are valid for operation
with the drive controllers under rated conditions.

l Ambient temperature - controllers
– The rated data and the derating for higher temperatures still apply for the
ambient temperature of the drive controller.
l Heat distribution between common heatsinks/coolers within the control
cabinet
– If you mount several components (drive controller, brake units etc.) on a
common cooler, then care must be taken that the temperature of the
controller heatsinks does not exceed 75 °C.
