There is two of samples for grounding below.
Using a grounding wire
Using listed EGC
• Determine the size of an external ground wire according to Article 690.46, NEC2014.
(Equipment grounding conductors smaller than 6 AWG shall be protected from physical damage.)
• A grounding conductor with insulation or bare (no insulation) may be used, provided the terminations are reliably
available.
• Use equipment grounding conductors approved by Article 250.118, NEC2014.

• LG AC module includes DC cables in the module’s internal wiring, so no grounding is required for DC input.
• For equipment grounding, LG AC Module uses an external grounding equipment conductor. AC cable does not
provide a grounding conductor, grounding is provided only by the external connection to the module frame.
