WIRING ( continued )
Units supplied with the AC input bypass option will wired slightly differently. To
conform to NEC 250 the neutral is “carried through” to the output but is not shorted
to the GND terminal. This will place one side of the inverter output at the neutral
potential. It should be noted that this is only recommended to satisfy the NEC
requirements. The output of the inverter is isolated from the DC input and the line.
This allows the output to be floating if required by end user’s application. Maximum
continuous common mode potential is limited to 250Vac or 360Vdc. Figure 2-2
illustrates a typical bypass configuration.

The recommended wire size for each model is listed below in table 2-1. These sizes
are based on a maximum wire length of 10 to 15 feet. Longer wires should be
increased in diameter.
