First connection to the grid

11. First connection to the grid
This chapter details the process for the inverter's first connection to the grid.
First review the unit.

11.1. Unit inspection

You must check the correct condition of the installation before start-up.
Each installation is different, depending on its characteristics, the country in which it is located or other special
conditions which may apply. In all cases, before starting up, it is necessary to ensure that the installation complies
with the applicable legislation and regulations and that at least the part to be started up is complete.

11.1.1. Inspection

Before inverter's first connection to the grid, you must carry out a general inspection involving mainly:
Wiring inspection
• Check that the cables are correctly joined to their connectors.
• Check that these cables are in a good condition and that there are no hazards in their environment which
damage them, such as sources of intense heat, objects which could cut them or arrangements which put
them at risk of impacts or pulling.
• Check the polarities of the DC and AC cables.
Review the unit's fastening
Check that the unit is secured firmly and is not at risk of falling.

11.1.2. Hermetic sealing of the unit

Ensure during installation operations that the unit's level of sealing has not been altered during connection of the
unit.
Check the correct adjustment of the connectors and that any cable grommets are well sealed.
Check that a torque of 6 Nm has been applied to the housing closure screws.

11.2. Process for the first connection to the grid

The first time that the inverter is powered from the PV array, a series of screens are displayed so as to guide the
inverter's configuration for proper connection to the electric grid.
