There is no negative in AC wiring and none of those are for ground. There might be a screw somewhere on the metal casing that you can run the ground to.

LS is Switched Live.

A lot of times these are used with switches/timers.

So your L - Live
N - Neutral
LS - Would be a switched or timed live leg
eg:
If you had a light switch on it, the light switch would be fed by a live cable, then it would have the live coming out of the switched side, then you would junction this together with a light and run that "switched Live" to the LS terminal on the fan. Same concept applies with a timer. It means that, that leg is not always live, that it is "switched".

You have two lives and a neutral...


SO

SWITCH/TIMER - LIVE---------------------------------------------LS
LIVE----------------------------------------------------------------L
Neutral------------------------------------------------------------N
Ground--------------------------------------------------------------Somehwere there is probably a screw on the metal that you can ground to.

Manufacturers like this have two types of fans, a switched live and a regular fan. Honestly you probably wanted the regular model but may have bought it because it said timer/switched fan. What that is for in applications like a bathroom exhaust fan or HVAC fan, where you have a second live signal coming from a switched source. So the LS is still a live wire, it is just meant to be for a switch. Their normal model doesn't have LS, just L/N.

It is meant for something like this
(Sorry just used paint real quick)

A lot of times you may have a light switch that ties off on the switched live and goes to a light at the same time, or a thermostat or timer that cuts the fan on and off using the switched live leg.

If it was earthed wouldn't that make a potential shock hazard?
Live leaking into earth would make the fan live, no?
I know that live leaking through the earth would shut of the power but that's isn't gteed safe, no earth is, afaik its a safety circuit it doesn't play a part in working anything?
Who knows about leccy?

After a bit googling double insulated items don't require an earth, they're designed that the live can't touch the body.
Fwiw the casing can become live but it should be picked up by a circuit breaker.
Thank you Google!
