[RE-wrenches] Trace or Outback autotransformer: step down but source has no neutral

[Mick Abraham]

Greetings, Wrenchies~

Below I've pasted a visual from the Trace T240 transformer product guide,
circa 2000:

My client's 240vAC 60 hertz source circuit has the two hots but no neutral.
They'd like to run some 120v tools & appliances, hence the autoformer. I
see in the diagram that a neutral from the input side is not required, but:

* In that event, can I ground the newly derived neutral without causing
havoc? The main home where the 240v wires originate is about 150 feet away
& the AC neutral is single point grounded there.

Other cautions or caveats? Thanks in advance. The Wrench List is The Bomb~
