Grounding
Connecting the protective ground for the NRG Controller
The NRG controller is equipped with a metal contact clip at the back of the product to provide functional grounding
via the Din Rail. The Din Rail must be conductive and grounded. Shielded Cat 5e cables fitted with an outer metallic
shell should be used. The shell should be connected to the wire screen of the cable.
