LE-03MP
Electric energy meter,
3-phase
The LE-03MP is a static (electronic) calibrated electricity meter
of three-phase alternating current in a direct system. It is used
for reading and recording of consumed electric energy and ma-
ins parameters with remote readout via a wired RS-485 network.
Under the influence of flowing current and applied voltage, the
LE meter accurately measures the amount of consumed electrici-
ty. Energy consumption is indicated by flashing LEDs: 800 pulses/
kWh for active power and 800 pulses/kvar for reactive power. In
addition, the device measures the mains parameters. The values
are displayed cyclically on LCD display. Parameter changes every
3 seconds. You can manually switch between successive parame-
ters by pressing a button on the front-end of the meter.
The display is active only with meter power supply on.

Do not dispose of this device in the trash along with other waste!
According to the Law on Waste, electro coming from households free of charge and can
give any amount to up to that end point of collec� on, as well as to store the occasion of
the purchase of new equipment (in accordance with the principle of old-for-new, regard-
less of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the
environment and human health.

The meter has an internal relay that switches L1, L2 and L3 cir-
cuits. The (ON/OFF) relay can be also operated manually.
The meter has a program overcurrent protection. If the load
threshold is exceeded, the internal relay opens for 5 minutes.
After that time the relay closes and the measurement is repe-
ated.
Prepaid power (prepayment feature) is the set increment value
of available active power beyond which the internal relay is di-
sconnected by the meter.
Automatic operation is the mode with two active functions: au-
tomatic relay disconnection if the set overcurrent threshold is
exceeded and switching on the prepaid mode.
Current state of relay (ON/OFF) is indicated on the LCD display as
the corresponding Modbus register value.
Readout of all measured values and parameter setting functions
is done via the Modbus RTU protocol.
Communication with the meter working as a Slave is performed
in accordance with Modbus RTU standard via RS-485 serial port.
Converted registers values give results consistent with the indi-
cations on the meter display.
Each indicator is identified by a unique address assigned by the
user.
IrDA (infrared data transmission ) feature is inactive in the
current version of the software.

»Internal relay switching L1, L2, L3 phase circuits.
»Remote control of ON/OFF relay.
»Overcurrent protection – setting the load threshold.
»Prepaid power (prepayment) – active power value at which
the meter disconnects the internal relay.
»Automatic mode – activation of overcurrent protection and
prepaid mode.
»Status – current status of the relay [ON/OFF].

The indicator has a pulse output. This allows you to connect a
pulse meter-reading pulses generated by the counter. For proper
operation of the indicator is not required to connect additional
devices.

Change of meter address is done via the RS-485 port using the
Modbus RTU protocol command to set the desired value in the
meter register. The default meter address: 1.
The meter is marked with individual serial number allowing its
unambiguous identification. The marking is laser engraved and
cannot be removed).

»Please read the instructions carefully before installation.
»The device should be installed and operated by qualified per-
sonnel who are familiar with its design, operation, and asso-
ciated risks.
»Do not install a meter that is damaged or incomplete.
»The user is responsible for proper grounding of the system,
proper selection, installation, and efficiency of other devices
connected to the meter, including safety devices such as over-
current, residual current and overvoltage circuit breakers.
»Before connecting the power supply, make sure that all cables
are connected correctly.
»It is essential to observe the operating conditions of the meter
(supply voltage, humidity, temperature).
»To avoid electric shock or damage to the meter, turn off the
power supply whenever the connection is changed.
»Do not make any changes to the unit yourself. Doing so can re-
sult in damage to or improper operation of the device, which
in turn can pose a threat to people operating it. In such cases,
the manufacturer is not responsible for the resulting events
and may refuse the provided warranty in the event of a com-
