2) Grounding by using grounding clamp

The grounding clip assembly consists of a slider, base, and self–captivating thread–cutting screw or

8–32 screw and hex nut. The grounding clip accepts solid uninsulated copper wire sizes 10 or 12 AWG.

We recommend customers use SolKlip Grounding Clip Assemblies 1954381–[]; SolKlip Grounding

Clip Assemblies 1954381–[ ] are used with metal–framed photovoltaic (solar) panels and related products
that require grounding for safety reasons.
3) Addition Third-party Grounding Devices

DMEGC PV Modules can be grounded using third party grounding devices so long as they are

certified for grounding modules and the devices are installed according to the manufacturer’s specified
instructions.

7. Maintenance and care

It is required to perform regular inspection and maintenance of the modules, especially during the

warranty period. To ensure optimum module performance, DMEGC recommends the following
maintenance measures:
