Mounting in "cold plate" technique

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−Cxx must be used.
Mounting material required from the scope of supply:
Description
Fixing bracket
Sheet metal screw
3.5 × 13 mm (DIN 7981)
Requirements for collective coolers
The following points are important for the safe operation of drive controllers:
Good thermal connection to the cooler
ƒ
– The contact surface between collective cooler and drive controller must be at least
as large as the cooling plate of the drive controller.
– Flat contact surface, max. deviation 0.05 mm.
– Connect the collective cooler with all specified screw connections with the drive
controller.
Do not exceed the thermal resistance R
