Grid Connection Guidelines; Connecting The Ac Grid To The Safety Switch - SolarEdge UL1741-SA Installation Manual

Grid Connection Guidelines

In single phase inverters connected to corner grounded grids, connect the L2
terminal to the grounded conductor. When connecting to other grids, L1 and L2 are
interchangeable.
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 installations must use components that are rated NEMA 3R or higher.
NOTE
For more wiring information refer to the SolarEdge
Recommended AC Wiring Application Note , available on the

Connecting the AC Grid to the Safety Switch

1. Strip 5/16'' (8mm) of the AC wire insulation.
2. Insert the AC conduit into the AC-side drill guide that was opened.
NOTE
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.
3. Connect the wires to the appropriate terminal blocks according to the labels on the
terminal blocks (N,
4. Use a standard flat-blade 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.
a. Insert the screwdriver and press the release mechanism and open the clamp.
b. Insert the wire into the round opening and remove the screwdriver – the wire is
automatically clamped.
5. Verify that there are no unconnected wires.
