What does 1/N mean in power descriptions (Europe and US)?

It means 1 phase wire and one neutral wire at 230V.
They are on a different system. There one phase and one neutral is 230V
Here it’s 120V

it could work here on 240 as long as there is not an internal grounding system

So do you think this terminology is improperly used in the US case? This is an electrical spec for a job on working on. If it's one phase and a neutral in the US wouldn't they call it 1/N 120VAC 60Hz???

Can be design dependent to some degree. Many cases all that really matters is that the equipment sees rated volts and possibly frequency. Might be designed to be a little safer if the grounded neutral is on a specific terminal - like here in the US is preferred to have shell of lampholder have the grounded conductor connected to it if there is a grounded conductor, improves safety a little should you contact the shell.

Most IEC countries utilize a three phase wye system that is 400-415 phase to phase and 230-240 phase to a grounded neutral.

In more remote areas with no three phase they just use 230-240 two wire with one line grounded and still call that grounded conductor "N" AFAIK.

Many single phase equipment designed to use both in North America or in IEC land will still have one terminal marked "N" and it is preferred to land the grounded conductor there if you have one, otherwise it does still work in North America on typical 120/240 systems connected "line to line".
