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.
