Assembly
1. Disconnect the power.
L 2. Mount the indicator on a rail in the distribution box.
3. Connect input phase to terminal 1. Connect wire N to terminal 4.
4. Connect a measured circuit or a single receiver to terminal 3
(output phase L) and to terminal 6 (N).
5. Optionally connect the RS-485 network wires to the 20 (A+) – 21
(B–) terminals.
6. Put the covers on the terminals and optionally seal them.

meter, including security devices such as overcurrent protection
breakers, differential switches and surge protectors.
* Before connecting the power supply make sure that all cables are
red LED
connected properly.
* Always follow the operational conditions of the meter (voltage,
humidity, temperature).
<27 mA
* In order to avoid electric shock or damage to the meter, discon-
90 ms nect the power before each change in connection configuration.
<20 m
* Do not modify the device on your own, as this may cause damage
