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 EVF93xx−CV must be used.
Required mounting material 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 safe and reliable operation of the controller:
Good thermal connection to the cooler
ƒ
– 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.
