Mounting with thermal separation (push−through technique)
With push−through technique, the rear panel of the control cabinet must be a steel
plate with a minimum thickness of 3 mm.
The edges of the mounting cutout and the fixing holes for the wire clamps must be
slightly curved to the inside (to the capacitor module).
Cooling
The separate heat sink reduces the heat development in the control cabinet.
ƒ
Distribution of the power loss:
–
approx. 65 % via separated cooler
–
approx. 35% inside the capacitor module
ƒ
Protection class of the separated cooler: IP54
–
The sealing surface of the capacitor module at the heat sink must rest
completely on the mounting plate.
–
Seal the screws for the wire clamp with liquid thread seal (e.g. Loctite 620).
ƒ
For sufficient cooling of the drive system:
–
Air flow behind the rear panel of the control cabinet ³ 3 m/s (e.g. through
the use of a collective fan).
ƒ
With sufficient cooling, the rated data of the capacitor modules remains
valid.
