Requirements for cold plate installation – size 0 only

The frequency inverter power loss can be dissipated via coolers that work with different cooling media (air, water, oil, etc.). This can be useful, for example, in restricted installation spaces. When heeding the usual installation notes (40 °C/100 mm (3.94 in) space above and below), cold-plate technology is not necessary.

A good thermal connection to the cooler is important for safe operation of the frequency inverters:

• The contact area between cooler and frequency inverter has to be the size of the frequency inverter cooling plate.
• Level contact surfaces are required, maximum deviation 0.05 mm (0.0002 in).
• Connect cooler and cooling plate with all necessary screw connections.
• The mounting plate must not exceed 70 °C during operation. This must be ensured by the cooling medium.
• Cold plate installation is not possible with FHS or FKB.
