4.2.3 Mounting in "cold plate" technique
For this mounting variant you require the controller type E82CV...
The following points are important for safe and reliable operation of the controller:
ƒ Good thermal connection to the cooler
– The contact surface between the collective cooler and the controller must be at
least as large as the cooling plate of the controller.
– Plane contact surface, max. deviation 0.05 mm.
– When attaching the collective cooler to the controller, make sure to use all
specified screw connections.
ƒ Observe the thermal resistance R
th
given in the table. The values are valid for
controller operation under rated conditions.

Ambient conditions
ƒ The rated data and the derating factors at increased temperature also apply to the
ambient temperature of the drive controllers.
ƒ Temperature at the cooling plate of the drive controller: max. 75 °C.
