Grounding

：

All permanently mounted modules have to be provided with appropriate

grounding. The grounding lug should be suitable for outdoor use with aluminum. The

grounding method of the frame of arrays shall comply with the NEC, article 250 and also

meet UL 1703 standard. Lay-in-Lug ground part with 32 threads per inch (e.g.

the lay-

in-lug with UL file number E34440, part # GBL-4DB), with size #10-32 ½ inch stainless

steel thread cutting screw, and using a 20 lb*inch torque, should be mounted to one of the

4 mm diameter grounding holes marked as grounding hole on the frame. When the

module system is used, it should be connected to the ground reliably. The ground wire

should be a naked copper wire with surface coating only and with no insulation jacket.

The area of cross-section of wire should be sized in accordance with the prime current

carrying conductor. The area of cross-section of wire should meet the NEC, article 250.

Installation in Canada shall be in accordance with CSA C22.1, Safety Standard for

Electrical Installations, Canadian Electrical Code, Part 1 ( refer Figure 3)
