operation when the intake neutral is not connected
If the decision is taken not to connect the intake neutral, proceed as follows:
1. Access the main terminal strip located in the electronics block of each power module.

2. Remove the link between XAc.0 and XAc.1
3. Repeat this operation for each power module
This will eliminate any type of interference in the voltage intake.

5.4.15. connecting to the PV array

The cables for connecting the unit to the PV array enter through the conical glands in the base.
Before any handling, check that there is no electrical hazard in the voltage input from the PV array.
never forget that whenever they receive solar radiation, the panels' terminals generate voltage.
The inverter can therefore have voltages of up to 1000 V inside even when not connected to the grid.
When checking that there is no voltage, wearing dielectric gloves and safety goggles approved for
electrical hazards is required.
connect the positive pole of the panel series to the terminals marked

If the distance between the inverter and the PV array connection point requires the use of longer cables, an external
distribution box must be used close to the inverter to make this connection.
The units have as many independent PV array input plates as electronics blocks.
The unit power should be distributed evenly between the number of inputs available. each one has its own positive
and negative plate. each plate has three M12 metric holes for six ring-terminated cables with a recommended size of
