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−Cxx must be used.
Requirements for collective coolers
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.
