Figure 6-405 Conceptual diagram of a 1+1 parallel system
For a three-phase three-wire parallel system, connect cables according to the
preceding conceptual diagram. In addition, connect the mains input neutral wire
of each UPS together using a single 185 mm

A parallel system where three-phase three-wire input and output cables are connected
using a busway is not supported currently.
A dual-bus parallel system consisting of two parallel subsystems is used as an
example.
