LEM-04 device is a single-phase
electricity meter, which can be used as
a electricity sub-meter for single-phase
AC circuit. Measurement of electricity
consumption is signalled by LED and its
value is indicated on LCD. The meter is
also equipped with pulse output allowing
connecting an additional counting device.
To protect the device against the illegal
power consumption LEM-04 is protected
with plastic enclosures on the terminals,
which can be sealed.
The device should be con-
nected to a one-phase network
in accordance with legally bind-
ing standards. The connection
method is described in this
manual. Any activities related
to installation, connection, and adjustment
shouldbeperformedbyqualiedelectricians
who have read this user’s manual and famil-
iarised themselves with device functions. Re-
moving the enclosure voids the warranty and
poses a risk of electric shock. Before instal-
lation, make sure that there is no voltage on
connection cables. To install the device, use
a cross-head screwdriver with a diameter of
3.5 mm. The proper operation of the device
is affected by how the device is transported,
stored, and used. It is not advisable to install
the device in the following cases: lack of any
components, damage to or deformation of
the device. If the device operates improperly,
please contact the manufacturer.
NOTE
Do not dispose of this device together
with other waste! To avoid harmful effects
on the environment and human health,
the worn-out device should be stored
in designated areas. Electrical waste
from households may be handed over
to the waste collector established for
this purpose free of change and in any
amount, as well as to the store when
purchasing new equipment.

ASSEMBLY, OPERATION
1. Disconnect the safety power supply
circuit, the overcurrent circuit breaker
or the isolating switch connected to the
corresponding water circuit.
2. Check voltage-free condition on the
supply cables with proper instru-
ment.
3. Install LEM-04 in the switchboard on
TH 35 (DIN) rail.
4. Connect the wires to the terminals in
accordance with the wiring diagram.
5. Switch on the power supply.
Current owing throught the device
causes that generated pulses are propor-
tional to amount of drawn electric energy
(2000pulsesperkWh).AashingLEDin-
dicates current consumption and the fact
that the device is measuring. The value
can be read from segment LCD. The
digits after the decimal point indicate the
hundredths of 0.01 kWh (10 Wh).
NOTES:
• When using pulse input (terminals
20, 21) it is necessary to apply addi-
tional supply voltage within a range
5 ÷ 27 V DC.
• It is recommended to use an addi-
tional resistor R (470 Ω ÷ 1 kΩ) to
limit the value of current.
• Changing the power supply polarity
may damage the indicator’s pulse
output.
• If there is no connection then the
metering device should not be con-
nected to pulse output of the supply
system.
