Select the “F: Floating” or “R: Redundant” option when ordering UPS units configured in
this manner.
Contact the SynQor factory for redundant Split Phase systems, redundant 3-Phase systems, or
redundant Single Phase systems with more than three units.
Parallel Connection of the AC OUTPUTS
Two or three SynQor UPS units can have their AC OUTPUTS connected in parallel to deliver two
or three time the output power and output current of a single unit. Units can also be connected
to form 1+1 or 2+1 redundant systems.
Two UPS units with AC OUTPUTS Paralleled
For two UPS units having their outputs connected in standard parallel or redundant parallel, the
wiring diagram for the AC OUTPUT cables and the CONFIGURATION cable is shown below:

When ordering, select the “F: Floating” or “R: Redundant” option for UPS units configured
in this manner. Use CONFIGURATION cable SYN-9311 for standard parallel and SYN-9341 for
redundant parallel.
If the user is providing the AC OUTPUT cable, the cable sections shown above in either blue or in
red should have the following minimum wire size, depending on whether the AC OUTPUT of the
UPS units is 115 Vac or 230 Vac.
