Note
Do not put into fire!
Do not open the capacitor!
To avoid health and fire hazards, do not
operate the capacitor beyond the voltage or
temperature limits given in the data sheet.
Any excess may also result in a reduction of
lifetime.
Please pay also attention to the transport
and waste disposal instructions in chapter
"Cautions".
