At strong currents, as can occur in parallel connections, the risk of warming of the connections is
higher. To avoid this risk, use an adequate sizing of the cross section.
The solar cables must be approved for the possible maximum short circuit current.
Make sure that other electrical system components may have no adverse effect on the modules.
Detailed information about the connection technique, solar cable and
connectors/plugs
Only use cables and connectors/plugs which are approved and tested for photovoltaic applications.
The choice of cables for the use in the photovoltaic generator must be based on sizing by a skilled
person. Cables with a cross section from 4mm² to 6mm² are recommended. The optimum cross
section should be determined by the maximum short circuit voltage and the complete length of the
wiring (line voltage drop).
Only use high quality cables to assure a failure
– free operating. Ensure good isolation and
whether/UV-durability of the cables.
The rated voltage of the solar cable must be 1000V minimum.
If possible, use flexible cables to ensure consistency against movements, wind etc. This will make
the laying of the cables easier (please find detailed information in the next clause).
Only use tools which are approved for cutting, isolating etc. of the cables or employ qualified
persons/staff.
Only use connectors / plugs which are approved and tested for photovoltaic applications.
Only plug in the connectors when dry and clean. Make sure that they are properly connected.
The connector system is fully latched only when the snap arm is fully obvious in the inspection
window. Take care of the clearance.
When disconnecting the connector, open the lock with the opening tool and pull the connector
apart.
For information about the compatible cables, please refer to the respective connector system
manufacturer.
Further information about the plugs/connectors can be found in the manufacturer's documents:
Stäubli Electrical Connectors MC4: MA231
Stäubli Electrical Connectors MC4 EVO2: MA273
Safety note: DO NOT disconnect the plugs/connectors under load! NEVER disconnect when
the system is in operation! Non-compliance is FATAL. You will find the safety note also
printed on the photovoltaic module product label and on the system plugs.
