Wye Output Transformer
The Wye Output Transformer controls the firing of the SCRs on startup, which minimizes the inrush into PDU
transformers. Output breakers and PDU input breakers have to be closed when you start up the system. Based
on whether the input side of the PDU transformer is configured as a Wye or Delta changes the firing sequence of
the SCRs.
If the Liebert STS2 is connected to a PDU configured as a Wye:
• Select YES for the Wye Output Transformer choice in the System Options dialog box.
Remote Source Selection
If your system is configured with the optional Remote Source Selection, it must be enabled from the System
