Notes before connecting
1. Do not connect L1, L2 or L3 to N
2. In order to avoid moisture in the meter due to condensa-
te 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

Wiring diagram
The secondary, mains current transformer
connection is to be connected to the phase to
be measured and therefore the transformer
don’t have to be grounded.
This connection is to be fused according to the local
installation instructions.
