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.
