7. Grounding Requirements (UL)
Equipment grounding requirements must be checked in accordance with the applicable regulations and standards before work is started.
The module frame or array must be grounded to avoid the hazards of electric shock or fire. The position of possible grounding connections can be found in Fig. 3-1.
An equipment grounding conductor can be fixed to the holes in the frame. Copper ground wire or equivalent to be used:
The grounding wire can be mounted on one of the designated holes in the module frame (see fig. 3-1).
Avoid contact corrosion when using different metals and observe electro-chemical insulation rating.
As an option, UL-467 approved bonding and grounding devices, including Burndy (formerly WileyElectronics) Washer Electrical Equipment Bonding (WEEB) and
similar devices, which penetrate the anodized layer of the module frame during installation can also be used for grounding the solar modules. These UL-467
approved devices are available together with grounding terminals (for the connection of the mounting system to the earth) from the manufacturer.
Observe the applicable regulations.
