3.3.3 AC and Ground Connection
The following describes how to connect the AC and ground cables
between the inverter and the AC grid:
1) Connect the Ground cable as shown in Figure 3-21A or 3-21B item 3
- Bond the Inverter to local grounding point – drive ground rod or
equivalent.
2) Remove the waterproof plugs from the AC output of the wiring box and
install appropriately sized conduit and conduit fittings into the hole.
Then route the cables through the conduit inside the wiring box.
3) A Circuit Ground should be run with the AC Power cables and
connected to the internal ground bus.
4) A separate Ground wire should bond the Wire Box to the local ground
connection for personnel safety. By bonding at this location is easy for
operator to determine the inverter is safely grounded.
5) Connect the AC (L1, L2, L3, N) cables to the terminal block and
connect the ground cable to the internal grounding terminal block. The
Neutral conductor is not required.
