* Please read the manual carefully prior to installing the meter.
* The meter should be installed and operated by qualified per-
sonnel familiar with the construction, operation and any
hazards involved.
* Do not install the meter if it is damaged or incomplete.
* The user is responsible for proper grounding, selection, instal-
lation and functionality of any other devices connected to the
meter, including security devices such as overcurrent protec-
tion breakers, differential switches and surge protectors.
* Before connecting the power supply make sure that all cables
are connected properly.
* Always follow the operational conditions of the meter (voltage,
humidity, temperature).
* In order to avoid electric shock or damage to the meter, discon-
nect the power before each change in connection configu-
ration.
* Do not modify the device on your own, as this may cause dama-
ge or improper operation of the meter and consequently
expose the users to risk. In these cases the manufacturer is not
liable for ensuing events and reserves the right to refuse the
warranty claims on the counter.

1. Disconnect the switching station power.
2. Mount the meter on the TH rail in the distribution box.
3. Open the covers on the terminals.
4. Connect the power to terminal 1 (L1 IN), terminal 3 (L2 IN),
terminal 5 (L3 IN).
5. Connect a measured circuit or a single receiver to terminal 2
(L1 OUT), terminal 4 (L2 OUT), terminal 6 (L3 OUT).
6. Connect wire N to terminal 7.
7. Optionally connect the RS-485 network wires to the 9(A+) -
8(B-) terminals.
8. Close the covers on the terminals and optionally seal them.
