Connecting the AC Grid
If the Safety Switch has a pre-assembled RGM (in single phase inverters), flip the RGM plate downwards before making the connections.
1 Insert the AC conduit into the AC-side knockout that was opened.
2 Connect the wires, and check that they are fully inserted and cannot be pulled out easily:
 Single phase 3-7.6kW inverter - Connect the wires to
the appropriate terminal blocks, according to the
labels on the terminal blocks. Connect the grounding
wire first. Use a standard straight-bladed screwdriver
to connect the wires to the spring-clamp terminals.
 Single phase 10-11.4 kW inverter - Connect the wires to the appropriate terminal blocks,
according to the label on the terminal blocks. Connect the grounding wire first. Use a
03⁄16" (5mm) straight flat-blade screwdriver to connect the wires to the terminals.
 Three phase inverter
 For AC/DC Safety Switch: - Connect the Ground and Neutral wires to the
terminal blocks in the AC side of the switch. Connect the line wires to the
appropriate connectors according to the label located in the switch.
 For DC Safety Switch: Use a standard flat-blade screwdriver to connect
the wires to the spring-clamp terminals
NOTE:
Three phase inverters require neutral connection at all times (only WYE type grids with neutral connection are supported).
3 Verify that there are no unconnected wires.
Connecting the Strings
1 Insert the DC conduit into the DC-side knockout that was opened.
2 Connect the DC equipment ground conductor to the equipment grounding terminal block.
NOTE:
Functional Electrical Earthing of DC-side negative or positive is prohibited because the inverter has no transformer. Earthing of module
frames and mounting equipment (equipotential bonding) is required per NEC.
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.
