Snubbercapacitors capacitors DC link and warnings Cautions Cautions and Warnings Mechanical overloads Attention: The capacitor is designed for mounting on a PC board. After it has been soldered to the PC board do not move the capacitor. The capacitor shall not be mounted on places where vibrations or accelerations occur. Do not exceed the tested ability to withstand vibration. Avoid any compressive, tensile or flexural stress. Note: Movement of the capacitor within the case can cause low insulation resistance, shorts, failure on terminals and the capacitor case. Overload Attention: Do not...
