Typical Rear Panel Overview
SG2K-1TXI, SG2K-2TXI & SG3K-1TXI, SG3K-2TXI Output Configuration
The SG -2TXI models provide three galvanically isolated 240Vac and 120Vac outputs. The
two 120Vac receptacles are an isolated and are derived split phase from the isolated,
center tapped 240Vac output. The center tap has been grounded to provide a derived
neutral for both 120Vac outlets. The 120V load must be split between the two 120Vac
receptacles. The combined power of all 208-240Vac and 120Vac receptacles must never
exceed the maximum rated output power of the UPS
WARNING: never attempt to connect the outputs from each of the duplex 5-15R or
5-20R receptacles together as they are connected to opposing 120Vac phases.
SG2K-2TX, SG3K-2TX & SG2K-1TX, SG3K-1TX Output Configurations
The SG -2TX models provide galvanic isolation only on the 120Vac outlets. The 120Vac
outlets have been limited to a 1400 watt maximum output. The 208-240Vac output is
supplied directly from the UPS inverter, which is not isolated. The 120V load must be split
between the two 120Vac receptacles. The SG -1TX models provide galvanic isolation only
on the 208-240Vac outlet. The 120Vac outlets are wired directly to the 120Vac inverter
output and upt to 100% of the load may be connected to the 120Vac outlets. As an alter-
nate configuration, both -1TX and -2TX models can provided with a single 120Vac output
with a derived neutral, please specify at the time of order. Note: The combined load of all
outputs must never exceed the total UPS output rating.
