Hy, i am assembling celing fan with speed pot. I have lost pin layout papers.
I goes from 220v to 60w.
Faze is wired to ttansformer that has 3 pins F L Gr faza has to go in f or in l and come from f or l to fan,.
Can i test the power of pind without geting fried, to be sure not to damage fan.

Are you sure this is a transformer? Normally ceiling fans are shaded pole and use a triac/dimmer style for control.
I would guess that I is input (power) and F is Fan.

Exactly, it's probably L for line power, F for fan load, and Gr for ground

Looking at this I would say L line power, F for fan, and Gr for ground also.

Sorry, I can't see enough of actual circuit to say for sure.
Normally, a fan rated dimmer is used in place of the wall switch.
This is located on the fan itself, or the wall?
the cable is coming from the fan load itself, or the household circuit?
What is the fan voltage, 240v?

The odd thing is there should be a Neutral (grounded) terminal next to it.

There is a possibility that L is for light if it has one attached.

I wouldn't guess at this.

I only see one cable. There should be one for line power (mains) and one for the load (the fan)

Unit shown is a choke. The two output cables are placed in series with the fan. The switch is a rotary type that switches out each tapping on the choke one at a time until the switch puts main supply direct on the motor for full speed. It makes no difference which line is which as far as L (line) and F ( fan) BUT the ground symbol is for an earth wire that connects to the choke laminations.

Ok, I see one cable on the top coming through the surface raceway, but I can't see where it goes. Then another below the rotary switch.
I'm just used to seeing (on this side of the pond)a terminal strip with L, N and ground grouped together. It appears the neutral connection in this case is that loose blue wire barely visible under the rotary switch.

Depends whether the installation loops at the fan or the control. Point being though that it has nothing to do with the operation of the choke shown.

Its a simple Choke with tappings in series with the fan to control speed. Had that on one of fans during the 60's.
