Connecting Earth Ground to an NFX350 Device

 

Earth grounding is recommended, but optional for the NFX350 device. The device functions normally without earth grounding. Electromagnetic Compatibility (EMC) and Electrostatic Discharge (ESD) requirements are met by the device. The AC power cord provides surge protection.

To connect NFX350 device to earth ground, you must use the protective earthing terminal on the device.
