Notes before connecting 

1.   Do not connect L1, L2 or L3 to N

2.   In order to avoid moisture in the meter due to 

condensate build-up, acclimatise the meter at room 

temperature for about half an hour before connecting.

3.   N must always be connected.

Attention!

These devices must only be installed by a professional 

electrician, otherwise there is the risk of fire or the risk 

of an electric shock.
