Grid Connection Guidelines; Connecting The Ac Grid To The Ac/Dc Safety Switch - SolarEdge 3000A-US Installation Manual

Grid Connection Guidelines


In inverters connected to corner grounded grids, connect the L2 terminal to the grounded conductor.
When connecting to other grids, L1 and L2 are interchangeable.

When connecting multiple inverters in an installation connected to a three-phase grid, phase
balancing may be required by the utility or grid operator. Phase balancing is supported in the
SolarEdge inverters. For detailed information, refer to the SolarEdge Phase Balancing Manual,
available on the SolarEdge website at
http://www.solaredge.com/files/pdfs/phase_balancing_connection_guide.pdf.
NOTES:

The conduits, hubs and fittings must be suited for field wiring systems.

The hubs and other fittings must comply with UL514B.

Use the conduit and wiring appropriate for the installation location per the NEC. Outdoor

For more wiring information refer to the SolarEdge Recommended AC Wiring Application

Connecting the AC Grid to the AC/DC Safety Switch

1
If supplied, remove the spring-clamp terminal instructions from inside the switch.
2
Strip 50 mm / 2'' of the external cable insulation and strip 8 mm / 0.32'' of the internal wire
insulation.
3
Insert the AC conduit into the AC-side knockout that was opened.
WARNING!
Connect the equipment grounding before connecting the AC wires to the AC terminal block.
Veillez à relier le conducteur de PE (la terre) avant de connecter les fils CA au bornier CA.
4
Connect the wires to the appropriate terminal connectors, using the label located in the switch.
Connect the grounding wire first.
5
Use a standard straight-bladed screwdriver to connect the wires to the spring-clamp terminals:

The screwdriver blade should fit freely in the terminal opening. Too large a blade can crack the
plastic housing.

Insert the screwdriver and tilt it to press the release mechanism and open the clamp.
