Install the Ferrites 

This procedure explains how to set up a ferrite to reduce EMI interference. The 
ferrite will be connected to the module’s relay contact connector.

1.

Obtain 0.25... 2.5 mm

2

 (22...14 AWG) wire in a length sufficient for 

your application.

2.

Twist the wires.

TIP

If you are not planning to use the relay contact connector on the 
module for system status, you do not need to install the ferrites.

TIP

You may want to choose a smaller wire gauge (for example, 

0.25…0.823 mm

2

 (22…18 AWG) with sufficient size and rating 

to handle amperage requirements of the power supply to aid in 
installation of the ferrite.

Use the key to open the ferrite. Remove the key and close the ferrite.
