When stacking in parallel configuration (GS8048A or GS4048A):
AC input and output conductors can share common connections from external AC input and output
buses. These are shown above.
Do not use the OutBack bypass assembly in the GSLC.
Connect all DC, PV, AC neutral (common), and ground wires as shown in the main GS8048A diagram.
Connect all CAT5 cables using the appropriate ports in the communications manager.
