M is the motor that drives the wheels of the clock.

Only in this model the "motor" is the electronic clock "Mechanism" so the terminals 1 and 2 will require power fed to them.

Probably this will be 230 volts AC but check the data sheet that came with the unit. It should matter which is Live and which is neutral.

A tidy way to wire it is

Neutral on 1

Live on 2 and 3

Switched live from 5

You will need a fuse in the supply to the Motor

Unless the lamps are massive a 2 amp fuse will suffice ( 400 watts of lighting )
