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.

 

 

Transportation-safe packing in cardboard boxes.
