Grounding Point
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, the controller
must be adequately grounded before power is connected. Connect a grounding cable to earth ground and then attach
it to the chassis grounding point using two screws.
Comply with electrical grounding standards during all phases of installation and operation of the product. Do not
allow the controller's chassis, network ports, power supply, or mounting brackets to contact any device, cable, object,
or person attached to a different electrical ground. Also, never connect the device to external storm grounding
sources.
