For the junction box to maintain its Class II safety standard, the cables must also be
Class II.
The ground wire must be
.To ground the modules, you must use a stainless steel
lug terminal
and a self-tapping screw between 4,2x4,5mm and 4,2x16mm. Esto
irá unido a un terminal de ojete semiaislado de 4mm .Ver imagen (10).
Make sure the lug terminal is placed between the wire and module frame. The wire
must fully clamped with the lug terminal and must make good contact with the frame.
There are two drill holes in the solar modules for this purpose, which are marked with a
ground connection (Earthing hole 4mm). View image of annex (11-12). The proper
torque values should be between 1,5 to 2Nm.
The photovoltaic system will be earthed according to the local and national regulations.

Connect the modules and the support
structure to ground, which will ensure that
any current leakage to any of the
components of the installation will not
reach the installer or user under any
circumstances.
The module frame material is aluminium.
