Order Of Connecting The Unit; System Wiring Diagram; Insulation Fault Contact / Grid Connection Indicator - Ingeteam Ingecon Sun Power Series Installation Manual

Installation manual
• Connecting the 230 V auxiliary supply (optional depending on the model and kit included)
CAUTION:
As long as the panels are exposed to the light, the DC cables will carry potentially dangerous voltage
levels.
Never handle the connections before disconnecting the inverter from the grid and the PV array.

5.4.3. Order of connecting the unit

The basic connections to be made with the Ingecon
1. Connecting the insulation failure detection switch (optional)
2. Communication line (optional)
3. Connecting the various grounding connections
4. Connecting the auxiliary supply (optional depending on the model and kit included)
5. Connecting the 3-phase inverter system to the power grid
6. Connecting the DC cables from the PV array
The following sections describe how to make these connections.

5.4.5. Insulation fault contact / grid connection indicator

The inverter incorporates a normally open volt-free auxiliary contact. It can be used for one of two functions:
• Detection of insulation fault in the DC circuit.
Open contact: there is no insulation fault in the DC circuit.
