asYGRID,totheDeltafuseholder,markedas∆GRID(see).
CAUTION!
The only supported delta grid is the 208V L-L grid. Connecting the inverter to other delta grids may
damage the inverter and will void the warranty.
To set the inverter for 208V delta grid connection:
NOTE
Perform this procedure for all inverter units.
NOTE
Perform this procedure before connecting the inverter to the AC grid.

CAUTION!
If the fuse was moved to support one of the grid types, do not connect the inverter to the other grid type
without switching the fuse back to the correct holder. Connecting the inverter to grids when the fuse is
incorrectly located may damage the inverter and void the warranty.
