5. Electrical Connection
5.1 DC Side Connection of Inverters
PV strings should be connected to the inverter through special PV connectors
that are in the scope of delivery.
It is recommended to use the DC cable of 4 mm
2
Assemble DC cables to DC connectors:
1) Strip the insulation layer off the DC Cable for about 7mm.
2) Insert the wire into the Crimp Contact and crimp them with an electrical
crimp-er.
3) Thread the cable through the Cable Gland, insert it into the insulator, and
gently pull backward the cable to ensure firm connection. Then screw up
the Cable Gland to the Insulator.
Install the DC connectors to the Inverter:
1) Turn the Grid Supply Main Switch OFF.
2) Turn the DC switch OFF.
3) Connect the DC connectors to the Inverter, small click confirms
connection. Please guarantee the correct polarity of the connection.
DANGER ELECTRICAL SHOCK
Lethal high voltage will be generated by PV arrays under sunlight, so
please disconnect DC and AC breakers and ensure no possibility of
re-connection before conduct electrical connection!
WARNING
Ensure that the open circuit voltage of PV array is within the max. input
voltage of the inverter!
NOTE:
Use DC cables specialized for photovoltaic systems Only!
NOTE:
Use only the supplied connector or the connector with IP 65
or above to guarantee that the protection ingress of the whole inverter is
IP66!
