PDPM288G6H: Install Manual Requires 4-wire Input. Is 3-Wire Acceptable?

Issue:
The installation manual requires a 4-Wire (3 phases + Neutral + PE) for the input and output.  This PDU has a transformer in it.  Can it be installed as a 3-Wire (3 phases + PE) on the input with the transformer creating a Neutral on the output for the load?

Product line:
Modular PDU

Environment:
All models, all serial numbers

Cause:
Customer requested information since 4-wire wasn’t available in the installation location.  The installation manual, one-line diagrams, and the service manual do not provide specification as to why 4-wire is required.
One Line Diagram
Resolution:
No, this PDU requires 4-wire on the input and output.
The input neutral is required since it is the same neutral used for the output.  The Auto Transformer doesn’t have a Star Point to create a the neutral needed by the load.
