Mounting Recommendation

Packing

Excessive mechanical strain, e.g. pressure or shock onto the capacitor body, is to be avoided during mounting and usage of the capacitors. When fixing the capacitor the screw torque is to be limited to max. 5 Nm.

Example for ordering / Part number:

Transportation-safe packing in cardboard boxes.
