Electrical Installation
Grounding
-
All module frames and mounting racks must be properly electrically grounded in accordance with
respective national electrical code and local authority.
-
A bolt, screw, or other parts used for bonding purposes within a module or panel shall not be intended
for securing the complete device to the supporting surface or frame.
-
Electrically ground the frame of the module or array to avoid the hazards of electric shock and fire.
-
Bonding shall be by a positive means, such as clamping, riveting, bolted or screwed connectors,
welding, soldering or brazing. If the bonding means depends upon screw threads, two or more screws,
or two full threads of a single screw must engage the metal.
-
The array frame shall be grounded in accordance with NEC requirements for grounding solar electrical
system.
-
The module frame must be properly electrically grounded.
-
The grounding wire must be properly fastened to the module frame to assure good electrical contacts.
-
Each long side frame has 3 grounding holes with 4 mm diameter and marked with a symbol “G” or
“ ” adjacent to their location for ground contact. In addition, there is a grounding hole at each short
side frame in order to increase operation friendly. The location of grounding holes are shown on Fig.
3.1.
