• Protection against the over-currents of all the polarities
• Fault signalling on the PV string (fuse indicator).
• Protection against atmospheric over-voltage
Optional functions
• Remote control switching OFF and disconnection.
• Canopy against solar radiations
1.2. GENERAL SAFETY RECOMMENDATIONS
• Always read this instructions manual before commissioning the equipment.
The DC voltage upstream fuse-disconnectors is never disconnected even the position of the switching products.
