• Do not touch electronic components or contacts.
• The Socomec Field Junction Box contains components that are sensitive to electrostatic charges and may be damaged if handled
improperly.
• Any use of damaged or spoiled components shall be considered as a non-compliance with the applicable standard.
It is forbidden to make any modification to the Field Junction Box without the prior
ried out using original spare parts.
agreement of Socomec.

3. INSTALLATION
3.1. ENVIRONMENTAL REQUIREMENTS
The following points must be considered for installation:
• The Field Junction Box is designed for both indoor and outdoor use.
• The Field Junction Box is exclusively designed for vertical fitting.
• Ensure a good flatness of foothold of the box fixations.
• If the wall is not flat, we recommend to use rigid profiles to fix the SOCOMEC Field Junction Box and to use wedges.
• The supports on which the Field Junction Box is fitted must be of non inflammable material. There must be no inflammable material
in the vicinity. If the device is fitted indoors, it is advisable to install a smoke detector.
• Ensure protection against wind, moisture, snow load and the direct exposure to sun radiation. (Special accessories may be
proposed by Socomec).
3.2. TRANSPORT – INSTRUCTIONS FOR HANDLING

4.5. INSTALLING THE FUSES
• Use only gPV fuses certifi ed for photovoltaic applications.
• Type de fuses: PV 10 x 38 gPV 1000V (compliance with IEC
60269-6)
• ISC STC max/string: 10 A
• PV module peak power current IMPP/string: 9 A
The rated current of the fuses must be calculated for each plant
•
separately (See maximum rated current ISC STC and Impp
STC values per string in the Technical Characteristics chapter).
• The fuse-holder terminals where the strings cables are
connected are always live even if the fuse holder is open.
• Before inserting the fuses of the strings, check the correct polarity of the inputs and check if there is no earth fault.
• Install/remove the fuses only after having disconnected the load (by opening the DC switch-disconnector) and using the appropriate personal protective equipment.
