3.2 Cooling space for capacitors
Make sure that su󹪟cient cooling space is provided:
• A minimum distance of 20 mm between the capacitors is necessary to maintain su󹪟cient
cooling.
• Keep at least 20 mm space above the capacitor and do not attach any mounting components
at the crimp or on top. This gap will allow a longitudinal extension of the can in order to
ensure that the over-pressure disconnector can fully extend.

Using reactors: cooling space for cables
If reactors are used in an application, note that they operate at a much higher temperature. The
distance between the reactor and capacitor must be large enough so that no reactor heat is
conducted via the connection cable to the capacitor, or that heat radiation from the reactor to
the capacitor causes overheating.
