Connection
In order to make connections between 2 UPS systems in parallel, two 6kVA UPS systems, the primary detachable PDU module and the secondary PDU module will be needed.
1Being sure that all switches are off and all units are powered down, refer back to the
“Mounting” section of the manual. First, mount the UPS systems and then the primary and secondary parallel PDUs.
2Originating from the secondary PDU interconnect port A , connect the parallel power interconnect cable B to the primary PDU C as seen in diagram 2.

When the unit is in Parallel Mode UPS system 1 will display “Parallel: Master” and UPS
system 2 will display “Parallel: Slave”.
8Once Parallel Mode is detected, turn on both output breakers for the primary and secondary PDUs.
