Grounding
Overview
The grounding resistance between the Slim Panel ground wire and the ground must be 100 Ω or
less. When using a long grounding wire, check the resistance and, if required, replace the wire with
a thicker wire and place it in a duct.
The table shows the maximum length for the wires:
