These suppression components are suggested as general guidelines. Contacting the load manufacturer is STRONGLY recommended as
1
they are best-suited to provide specific details on proper component selection for the load in use.
Orientation of diode is important. Make sure cathode (side with ring) is connected to the positive side of the DC power supply.
2
Actual wiring depends on specific product. Refer to the product rating for current and voltages.
