Mounting with thermal separation (push−through technique)
4.2 Mounting with thermal separation (push−through technique)
For the push−through technique the rear panel of the control cabinet must be a
steel plate with a thickness of at least 2 mm.
The edges of the mounting cutout and the fixing holes for the clamps must be
slightly curved inwards (towards the axis module).
Cooling
With the separated heatsink the heat generation in the control cabinet can be
reduced.
Distribution of the power loss:
ƒ
–
approx. 65 % via separated cooler
–
approx. 35 % in the inside of the axis module
Protection class of the separated cooler: IP54
ƒ
–
The sealing surface at the heatsink of the axis module must rest
completely against the mounting plate.
–
Use a liquid thread sealant to bond the screws of the clamps.
For sufficient cooling of the drive system:
ƒ
Air flow behind the rear panel of the control cabinet must be ³ 3 m/s
–
(e.g. by means of a collective fan).
With sufficient cooling, the rated data of the axis modules remain valid.
