SunEdison recommends using a copper or tin plated grounding lug that is rated for outdoor use and uses no smaller than a #12
wire. The use of a copper split bolt connector is authorized for use as well.
• Attach the grounding lug to the frame as follows and shown below in Figure 3:
Step 1: Uses stainless steel metric/english set only. The following is the minimum hardware metric (left) and english (right) required
by SunEdison.
Step 2: Place the grounding lug over the grounding hole on the exterior of the module frame.
Step 3: Place a star washer directly between the bottom of the grounding lug and the exterior surface of the frame.
Step 4: Place a bolt through the lug, star washer and frame grounding hole.
Step 5: Secure the lug to the frame using a flat washer, split washer and nut.
Step 6: Torque the bolt stack to approximately 1.5-2.3 N·m (or 1.1-1.7 ft·lbs) to ensure the star washer scratches the anodized
