Installation (from the manual)
Torque
| Clamp or bolt torque | torque should never exceed 11 ft-lbs (15 Nm)[5] |
|---|
Conductors
| Cable bending radius / connector notes | Maxeon recommends a conservative minimum bending radius (R) 5x cable diameter must be maintained and must not be bent on the direct exit of the connector or junction box.[5] |
|---|
Clearances and orientation
| Mounting methods and clamp zones | MAX6 66 cells with frame Gen 5.2 using Invisimount; no-hole mounting system has been evaluated to a wind and snow design load of 2873 Pa with clamp-mount method (End-mount method) and 1916 Pa with Quarter-mount method, with a safety factor of 1.5 minimum.; MAX6 72/66 cells with frame Gen 5.2 have been evaluated to a wind design load of 3600 Pa and snow design load of 6000 Pa with direct Quarter-mount method using mounting holes on the PV module, with a safety factor of 1.5 minimum.; MAX6 72/66 cells with frame Gen 5.6 have been evaluated to a wind design load of 3000 Pa and snow design load of 6000 Pa with direct Quarter-mount method using mounting holes on the PV module, with a safety factor of 1.5 minimum.; Modules are to be mounted to the Rail using the clamps located on the longer side, 50mm to 400mm from short edge of the module in portrait orientation;[5] |
|---|
Grounding
| Grounding | Attach a lay-in lug (Ilsco GBL-4DBT) to one of the grounding holes on the module frame, and attach the ground conductor to the lug.; Use an external-tooth star washer between the lug and the module frame in order to pierce the anodizing and establish electrical contact with the aluminum frame.; The assembly must end with a nut that’s torqued to 1.67–2.08 ft-lbs (for a #10-32 bolt).[5] |
