For conductors with finer stranding, a suitable UL listed wire ferrule
must be used.
Step 5
Pull AC cables through the conduit opening and connect the necessary
conductors to AC pressure type terminal blocks
y
For Wye grid, connect Neutral, L1, L2, L3, and PE conductors.
y
For Delta grid, connect L1, L2, L3, and the PE conductors to the corresponding
terminals on the AC Terminal Block.
y
Observe the pin assignment of AC terminal block. If a phase wire is
connected to the “PE” terminal, it may permanently destroy the inverter.
y
Please avoid squeezing the cable insulation layer into the AC terminal.
Improper connection may damage the inverter.
Additionally, when using a delta connection, the unused N terminal and PE terminal
must be connected with a short jumper cable (green or green/yellow) of 10AWG.
