Utility Configuration Jumpers
The SB3800U comes from the factory pre-configured for utility interconnection with
neutral. The SB3800U may be reconfigured for grids without neutral by setting the
jumpers on the board of the SB3800U.
The utility configuration jumpers allow the SB3800U to be connected to transformers
where the neutral is not present, such as the 208V and 240V Delta, shown in Figure 4-
3. Refer to the figure below for a description of jumper settings.
