Can anyone advise which connections are which, on this £1 electric coin meter? Here is a photo:

are four connections, lower left. Presumably they are: (not necessarily in correct order):1) Live, from mains
2) Live, to appliances
3) Neutral, from mains 4) Neutral, to appliances
But which is which? There is a basic circuit diagram stamped on the inside of the terminals cover (right picture) which may explain it to the enlightened.
I cannot see any earth connection. Should there be one?
Thanks for any help.
