Installation notes for basic unit – electrical aspects
Installation
lation 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 fre-
quency 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.
