Grounding
• For grounding and bonding requirements, please refer to regional and national safety and electricity
standards. If grounding is required, use a recommended connector type for the grounding wire.
• For grounding, this guide refers to module frame grounding. If grounding is required, make sure module
frames (metal exposed to touch) are always grounded.
• SUNMAN recommends always refer to local state and national code requirements for PV module
grounding. SUNMAN highly recommends negative grounding if it's allowed by local authorities.
• When attaching the frame grounding hardware and wire to the frame it must be placed corresponding
to the ground symbol stamped location to ensure proper electrical connection.
• For grounding should be performed by a qualified electrician.
For SMD Series
Grounding layouts
• Earthing of the array is a requirement as per AS5033 Australian Standards. In order to provide a
conductivity path between the panel frames, an earth lug has been provided on the frame of the panel.
The most efficient way to earth the panel and maintain continuity is to pull through the earth cable
through the ducting and fix earth cable at each lug. This branch of earth cable can then be connect to
the main return earth cable going back to a common ground.
