Mounting with thermal separation (push−through technique)
Mounting in push−through technique requires the rear panel of the control cabinet to be
a steel plate with a thickness of at least 3 mm.
The edges of the mounting cutout and the fixing holes for the clamps must be slightly
curved inwards (towards the power supply module).
Cooling
The separated heatsink serves to reduce the heat generation in the control cabinet.
ƒ
Distribution of the power loss:
– approx. 65 % via separated cooler
– approx. 35 % inside the power supply module
ƒ
Protection class of the separated cooler: IP54
– The sealing surface at the heatsink of the power supply module must rest
completely against the mounting plate.
– Use a liquid thread sealant to bond the screws of the clamps.
ƒ
Cooling of the drive system:
– Air flow behind the rear panel of the control cabinet must be
³ 3 m/s (e.g. by
means of a collective fan).
ƒ
With sufficient cooling, the ratings of the power supply modules remain valid.
