3-4-2 Ground Wiring

Grounding	Be sure to ground the earth terminal to less than 100 Ω in order to protect against
	electric shock and incorrect operation from electrical noise. Be sure to use a wire
	of at least 1.25 mm2 for grounding.

!WARNING During installation, be sure to ground to 100 Ω max in order to protect against electric shock.

Ground to 100 Ω max.
