7.3 Electrical wiring
• A set of cables with a plastic connector for each polarity is supplied with SF modules. Use these to connect modules.
• Do not open the junction box.
• 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.
