Earthing / Grounding

2
Use a cable at least 0.2mm (AWG24) to ground equipment. Ground resistance must be
less than 100Ω (class D). Note that the ground cable must not be connected to the same
ground as the power circuits. Grounding is recommended but if a proper ground cannot be
provided the PLC will still operate correctly without being grounded.
