Secondary section cooling connection

Connection options
For motors of the 1FN3 product family, you can use secondary section end pieces for the
flow and return lines of the secondary section cooling system.
If the continuous secondary section cover is not used, you can also connect the plastic
hoses directly to the heatsink profiles using hose connector nipples.
Properties of the plastic hose
The plastic hoses must be resistant to the cooling medium, flexible and abrasion resistant.
Note
Recommended manufacturers
You will find the recommended manufacturers for the plastic hoses in the appendix.
Connection via secondary section end pieces
To connect plastic hoses to secondary section end pieces, screwed joints with screwed
nipples and reinforcing sleeves can be used. You can attach the plastic hoses over the
screwed hose connector nipples with hose clamps.
For this connection, note the maximum outer diameter (12 mm) and the maximum width
across corners (width across flats 10) of the screwed joint or the screwed nipple:
If you choose larger screw joints or screwed nipples, you must provide appropriately
dimensioned recesses in the screw surface of the secondary section.
You can seal screwed nipples from the end piece in one of the following ways:
● Axially acting O-ring
● Sealing ring
● Thread seal
We recommend the use of conical screwed nipples
