Photovoltaic module mounting - Grounding

The module frame must be properly grounded. The grounding wire must be properly fastened to the module frame to ensure good electrical contact. Use the recommended type, or an equivalent, connector for this wire. If the support frame is made of metal, the surface of the frame must be electroplated and have excellent conductivity.

We recommend the lay-in lug when grounding (Cat. No. GBL4-DBT is recommended by the producer). Assemble the recommended grounding lug to the aluminum frame using a stainless steel M3 or M5 screw and hardware as shown below. Note: There are two different-sized grounding holes, the smaller of which is being phased out.

Further, the buildups of hardware for mounting the grounding lug are the same— except for the M3 screw, where an added lat washer is mounted directly under the M3 screw head. The star washer is fitted directly under the grounding lug and makes electrical contact by penetrating the anodized coating of the aluminum frame. The screw assembly is further fitted with a flat washer, then a split lock washer, and finally a nut to secure the entire assembly, as shown. The recommended torque of M3 or M5 screw assemblies is 0.8 NM or 1.5 N
