Mounting Recommendation

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 plates the screw torque is to be limited to max. 5Nm.

Packing

Transportation-safe packing in cardboard boxes. Packing quantities may vary depending on the plate version.
