MOUNTING INSTRUCTIONS FOR C140 KNS, C155A KNS, C170A

KNS CLAMPS

This type of clamp uses the elasticity of the bar material. The indicator of the load force is a tang

which is fixed on one side and free on the other. The perpendicularity of the load force is guaranteed

by a proper floating joint. In order to have a correct mounting, the following is recommended:

1. The two contact surfaces of semiconductor should be covered with a thin coating of an approved

joint compound and then any surplus should be removed.

2. Locate the semiconductor on one of the two heat sinks centrally by using provided pin after

having checked the polarity. The semiconductor should be rotated to spread the compound.

3. Position the second heat sink on the semiconductor and locate it centrally by using a second pin and

rotate the heat sink to spread the compound.

4. Mount the clamp on heat sinks and hand tighten each bolt, checking the alignment of the heat sinks

and semiconductor to make sure the heat sinks are parallel before starting to tighten the nuts with a

wrench.

5. Tighten alternately the nuts about 1/6 turn each until the clamping force indicator arm snaps into the

indent on the top bar. Tighten an additional 1/12 of a turn.

In case of disassembly of the clamp for a possible replacement of the semiconductor, before loosening

the nuts, flex the force indicator arm slightly outward to the point that it gets free from the bar.
