Procedure:
1) Prepare the positive and negative photovoltaic cables.
Insert the crimped positive and negative cables into the corresponding photovoltaic connectors.
1. Positive contact
2. Negative contact
3. Positive connector
4. Negative connector
Make sure that all the DC string parameters are acceptable to the inverter according to the technical specifications
given in the datasheet and in the Azzurro ZCS configurator. In addition, check that the polarities of the photovoltaic
cables are correct. Insert the positive and negative connectors into the inverter until you hear a “click” sound.
Before removing the positive and negative PV connectors, make
sure that the DC rotary circuit breaker is in the OFF position.
Use a MC4 wrench to disconnect the
photovoltaic connectors
NOTE: All MPPT inputs of the inverter should be populated, even if the system only has one
string. Use “Y” cables or a DC square to split the string.
Configure the inverter in parallel mode:
Basic settings  Channel configuration (Channel 3: PV input 1, Channel 4: PV input 1)
ATTENTION Before connecting/disconnecting the PV panels to the inverter,
check that the DC circuit breaker on the inverter is in the OFF position.
