Parallel Configurations of the AC OUTPUTS: Up to 32 Unit “R” option
The “R” option adds a single pole electronic breaker to the hot wire of the AC OUTPUT. This breaker
allows for fault-tolerant, glitch-free operation of up to 32 UPS units in a multi-system. Single-Phase,
Split-Phase, and 3-Phase systems can be formed. These systems can be N+1 or N+M redundant on
each phase.
The block diagrams below show a summary of the different system configurations that can be made
using units with the “R” option. Please note that each multi-unit system requires its own unique
system CONFIGURATION (Single-Phase, Split-Phase, and 3-Phase) cable. Contact the SynQor factory
to purchase the system specific configuration cables. Note that configuration cables for two, three,
four and five unit Single-Phase parallel systems are offered as standard products.
