Mounting instructions
To fully utilize their RF properties, the feedthrough components must be mounted directly into shiel
ding walls. The case must be contacted seamlessly (sealed against RF signals) to the shielding
wall. This can be best done by screwing it into a threaded hole or bushing so that contact is made
via the threads.
Alternatively, the feedthrough components may be screwed into feed-through holes on the shielding
wall by means of attachment nuts. The contact between case and the shielding wall is then set up
via the contact surface of the thread.
Recommended tightening torques for feedthrough components (capacitors, filters)

Caution
Contacts with rigid copper busbars are not permitted in view of mechanical stresses of the
bushings due to impacts and vibrations.
For types with screw connections, the connecting cable must be secured between two nuts
to exclude a torque on the feedthrough pins. The use of two flat wrenches is recommended.
