MOUNTING GUIDELINES
• The connection to one electrode must be flexible in order to prevent the generation of physical force which could damage the
capacitor elements. Such forces are often generated by the dimensional differences resulting from the normal physical
tolerances of these components.
• The capacitor elements must not be used as a mechanical support for other devices or components.
• Use two wrenches when tightening the nuts on both sides of the conductor rod.
The outer electrode terminal flange of these feed-through capacitors components should be fixed after tightening the inner
electrode’s connection.
• Make sure that not too much force applied to the solder connections between hardware and noble metal electrode. A torque
less than 5 Nm is recommended.
