7.3 Electrical Wiring
A set of cables with a plastic connector for each polarity is supplied with SF PV modules. Use these to connect
modules.
Do not open the junction box on the back side of the module
Fasten the module cable to the frame or to the mounting system in order to avoid any stress to the connector.
Cables drooping from the terminal box are hazardous and must be avoided.
Cables should be secured so they are not exposed to direct sunlight (such as behind the module).
The sum of Voc of modules in series must not exceed the maximum system voltage rating of the module under any
condition, even at low temperature.
Reverse current applied to the modules should not exceed 7 A under any condition.
Minimum cable diameter: 2.5 mm sq
