LE-03MQ CT
Electric energy meter,
3-phase
Directive MID 2014/32/EU
Certificate number 0120/SGS0216
The LE-03MQ CT is a static (electronic) calibrated electricity me-
ter of single-phase or three-phase alternating current in a semi-
-direct system.
It is used for reading and recording of imported electricity and
parameters of the power supply with the ability of remote reading
through a wired RS-485 network.
The meter works with current transformers (CT) with a seconda-
ry current of 1 A or 5 A.
Configuration of the meter is done through the configuration
menu accessible from the front panel and through the commu-
nication port according to the software features of the Modbus
RTU.
Compliance
Purpose
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 indicator has a SO+/SO- 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.
The meter has sealable input and output terminal covers to pre-
vent any attempts to bypass the meter.

»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
result 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
