Terminal lug requirements:
☐ Use tin-plated terminal lugs only.
☐ For the connection, only the supplied screws, washers and nuts must be used.
☐ The terminal lugs must be designed according to the temperature. Temperature: +95°C
☐ The width of the terminal lugs must exceed the washer diameter. The diameter of the washers for M12 screws is
32mm. The diameter of the washers for M8 screws is 20mm. This will ensure that the defined torques are
effective over the whole surface.
Cable requirements:
☐ The DC cables must be designed for the maximum PV voltage and must have double or reinforced insulation.
☐ No more than two cables must be connected to each DC terminal.
☐ Use copper or aluminum cables only.
☐ Maximum cable cross-section:400mm².
☐ Terminal lugs: M12 or M8
