Do not dispose of this device to a garbage bin with other unsorted waste!
In accordance with the Waste Electrical and Electronic Equipment Act
any household electro-waste can be turned in free of charge and in any
quantity to a collection point established for this purpose, as well as to the
store in the event of purchasing new equipment (as per the old for new rule,
regardless of brand). Electro-waste thrown in the garbage bin or abandoned
in the bosom of nature pose a threat to the environment and human health.

Dimensions
Pulse output
The meter is equipped with pulse output SO+ - SO-. This allows
you to connect another pulse device (SO) that reads pulses
generated by the meter.
No additional connected equipment is required for proper opera-
tion of the meter.
The meter has sealable input and output terminal covers
to prevent any attempts to bypass the meter.
The meter is marked with individual serial number allowing its
unambiguous identification. The marking is laser engraved and
cannot be removed.
Length of the SO+ SO- pulses depends on the load of the meter:
5÷40A 80 ms 75A 46 ms
45A 75 ms 80A 42 ms
50A 68 ms 85A 40 ms
55A 62 ms 90A 38 ms
60A 57 ms 95A 36 ms
65A 52 ms 100A 34 ms
70A 48 ms
Purpose
Functioning
LE-03 is a static (electronic) calibrated electricity meter of three-
phase alternating current in a direct system.
A special electronic system under the influence of flowing current
and applied voltage in each phase generates pulses proportional
to the energy drawn in the respective phase. Energy consumption
in the phase is indicated by a flashing of corresponding LED (A, B,
C). The sum of the three phase pulses is indicated by a flashing LED
(800 pulses/kWh) and converted into energy absorbed
throughout the three-phase system. Its value is displayed by the
segment LCD display. The fractional digit represent the decimal
(.1 kWh = 100Wh).

* 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.
