Re: Alignment
If you do connect the sig.gen. to the chassis- not recommended anyway - but if you do, and you've carefully checked that the chassis is at neutral, then as a last check before actually making the connection just stick a meter between the generator earth and the chassis. It should read 2v- 3v ac.
With the best will in the world one can always make a mistake; if the meter reads 240v you can correct things before making it.
