3 Mounting and Wiring
Individual earth conductors for each MICRO inverter:
•
The conductor linking the assembly to the grounding distribution structure must be at least
6 AWG.
•
The conductor bonding the MICRO inverter to the structure must have a minimum cross
section of 8 AWG (maximum length 1m).
• Ensure that the quality of the bond made between the conductor and the structure is secure.
Only a racking system that is certified for use as a grounding structure is permitted to use
this method.

Incorrect grounding can cause physical injury, death or equipment malfunction
and increase electromagnetic interference.
Make sure that grounding conductors are adequately sized as required by safety
regulations.
