4.1.3 Assembly with thermally separated power stage
(”push-through technique”)
The heatsink of the controllers 9321 ... 9329 can be mounted outside the control cabinet to reduce
the heat generated in the control cabinet. For this, you need an assembly frame with seal (can be
ordered from Lenze).
l
Distribution of the power loss:
– approx. 65% via the separated heatsink (heatsink + blower)
– approx. 35 % inside the controller.
l
The enclosure of the separated heatsink (heatsink + blower) is IP41.
l
The rated data of the controller is still valid.
Preparation for assembly:
1. Lay the halves of the assembly frame into the slot provided on the controller.
2. Push the frame halves together until the ends catch.
3. Slip the seal over the heatsink and lay into the slot provided.
