GCL Installation Guide
All the module frames and mounting structures shall be grounded according to
regional and national electricity regulations. Use recommended hardware to connect
grounding cables and fasten to the Module frames.
While using the metal structure, make sure the surface of the system have been
electroplated to keep a good conducting circuit.
Use suitable grounding conductors to connect the Module frame to the mounting
structure. This can achieve proper grounding eects.
The grounding conductor must be connected to ground via an appropriate grounding
electrode. It is recommended to use lugs to connect the grounding cables. If it is only
mechanically connected to a grounded module without bolts and nuts, the mounting
system should be grounded as well.
First, peel the grounding cable to a proper length withot damage to the metal core. Then
insert the peeled cable into the lug, tighten the screw. As shown in Figure 8, connect the
lug to the aluminum frame with stainless steel bolts and connection components. The
recommended tightening torque for M3 bolts is 2.3 N•m.
