NOTES:

1. THE DEPLOYMENT OF THE WEEB 11.5 WASHERS IS ONE (1)

PER PV MODULE. INSTALL IN THE SAME MODULE LOCATION

FOR EACH MODULE.

2 WHEN INSTALLING THE WEEB-11.5 INTO THE ZEE PURLIN

MODULE HOLES, ORIENTATION IS CRITICAL. THE WEEB

MUST BE POSITIONED SO THAT A PERSON LOOKING AT THE

WEEB FACING THE RACK (FACING NORTH) CAN READ THE

TEXT ON THE FRONT OF THE WEEB.

3. READ RBI'S GROUND MOUNT SYSTEM MODEL GM-I

ASSEMBLY INSTRUCTIONS AND RBI'S SOLAR DRAWINGS

FOR THE MANUFACTURER'S INSTRUCTIONS ON RACKING

AND GROUNDING.

4. RACKING GROUNDING LUGS CAN BE PLACED AT THE END

OF EACH ZEE PURLIN OF A CONTINUOUS SUB-ARRAY ROW;

MOST PREFERABLY ON THE SIDE CLOSEST TO AN

INVERTER.

5. MODULES SHALL BE WIRED FROM POSITIVE TO NEGATIVE IN
