Codes. The grounding conductor must then make a connection to earth using a suitable earth ground electrode. • Trina Solar modules can be installed with the use of third party listed grounding devices for grounding the metallic frames of PV modules. The devices have to be installed in accordance with the grounding device manufacturer’s specified instructions.
6.4 INSTALL EFFECT CHART The install effect chart is as follows. Please consult with Trina Solar engineers to confirm whether the rails match Trina clamp/frame or not. And confirm there are no shelter on the back of the modules. MODULE WIRING Each module has two 4mm diameter type standard 90°C sunlight resistant output cables each terminated with plug &...
Trina Solar is a member of the European PV Cycle Association. Through the pre-financed PV Cycle program, Trina Solar PV modules will be taken back and treated in an environmentally sustainable manner.*Applicable only to participating countries within the Europe Union.
