4.1.4 Mounting in "cold plate" technique
The drive controllers can be mounted in ˜cold plate˜ technique, e.g. on
collective coolers. For this purpose, the drive controllers of type EVS93xx−CKx
must be used.
Mounting material required from the scope of supply:

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.

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.
