1.1.  

GENERAL INFORMATION

Socomec Field Junction Box is designed to make the connection of groups of strings (photovoltaic panels) to an inverter in photo-
voltaic applications.

Basic functions :

•  Connection and combination of the photovoltaic strings

•  Switching OFF and disconnection of the DC voltage of the installation

•  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. 
The DC voltage level is dangerous. Any contact can cause an electrocution or an electric shock.

•  The devices shall be accessible to authorized personnel only.

•  Unauthorized opening of the device or improper interventions can lead to personnel severe injury, death or material damage.

•  Repairs on the boards must be carried out only by the manufacturer or by personnel authorized by the manufacturer.
