DC side Connection
NOTE
The cable length on DC side should not exceed 30 m.
DANGER
DANGER to life due to potential fire or electricity shock.
Never connect or disconnect the connectors under load.
NOTICE
If only one string input is used for DC connection, please use the sealing
plug to seal the left DC input set to ensure the inverter IP 65 protection.
NOTICE
Before electrical connection setup, installer shall make sure the inverter is
isolated and disconnected from the PV source and AC grid.
The inverter may only be operated with PV generators (Class A PV modules
according to IEC 61730 and cabling) of protection class II. Do not connect any sources
of energy other than PV modules to the inverter.
NOTICE
No mixed connections between input zones
For instance, if the positive pole of a string is connected at input zone 1 and
the negative pole at input zone 2, this is called a mixed connection.
Only connect strings at one input zone and never mix the input zones 1 and 2!
The DC connectors come pre-assembled and the caps are loose. The whole connector
