Figure 7-8: Closing the top cover's quick clamps
1 = Lift the inner clamp out of the lever
2 = Bring the inner clamp closer to the retaining lug on the top cover's edge
3 = While bringing the inner clamp closer, make sure to leave the lever in a low position
4 = Push the inner clamp over the retaining lug
5 = While bringing up the lever, make sure to position the inner clamp on the center of the lug (in the
green circle)
6 = Fully close the lever
7 = Here, the inner clamp is badly positioned, too far to the left
8 = Here, the inner clamp is badly positioned, too far to the right
5.
NOTICE! Risk of reduced shielding effectiveness. If the top cover is not installed
correctly, shielding efficiency can deteriorate dramatically.
We recommend that you measure the shielding efficiency after closing the cover.
7.4.3 Adjusting the locking force of the cover
Over time, the tension force that the quick clamps exert on the cover may change. This
is due to aging effects of the gasket.
●
Too high force becomes obvious if the quick clamps can hardly be closed by hand.
●
Too low force may result in a reduced shielding effectiveness of the top cover.
To adjust the tension force, shift the quick clamps up or down a little bit. This is suppor-
ted by an adjustment screw (1). However, do not rotate the holder screw (2) of the
inner clamp's hooked flap (3), because one rotation of this holder screw is typically too
much for adjusting the tension force.
