The LEM-40 digital, three-phase electricity
meter is a precision device measuring the pow-
er consumption in a three-phase system. The
meter operates in class B (equivalent to class
1). The device is equipped with a legible LCD
and signaling diodes informing about the pres-
ence of voltage of a given phase. ZAMEL LEM-
40 meter is used to monitor power consumption
of three-phase system in consumer, commer-
cial and industrial applications. The product is
ideal solution for billing the power consumption
in garages, workshops, plots of land, tenants of
facilities or for machinery control. The device
measures and displays electricity expressed in
kWh rounded to 2 decimal places (0.01kWh).
W results are presented on a 6+2 digital display.
Pulse output of the meter allows connecting
metering device and presenting the measure-
ment results on the additional display/system.
The meter can be easily installed in electric
cabinets because it has compact 4-module de-
sign (4 DIN modules). The device is equipped
withsafetyaps,whichcanbesealed.
The device should be connected
to a three-phase network in ac-
cordance with legally binding
standards. The connection meth-
od is described in this manual.
Any activities related to instal-
lation, connection, and adjustment should be
performed by qualied electricians who have
read this user’s manual and familiarised them-
selves with device functions. Removing the
enclosure voids the warranty and poses a risk
of electric shock. Before installation, make sure
that there is no voltage on connection cables.
To install the device, use a cross-head screw-
driver 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 oper-
ates improperly, please contact the manufac-
turer.
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.

INTENDED USE
ASSEMBLY, OPERATION
1. Before assembly you should familiarize
yourself with the manual and observe the
requirements related to location and con-
ditions of assembly. The assembly should
be carried out by a person with appropriate
authorizations.
2. All assembly works should be carried
out after disconnection of supply voltage
(measuring voltage).
3. Use only insulated tools.
4. The cables used should conduct the maxi-
mum current assumed for the given meter.
5. Check voltage-free condition on supply
conductors using a proper measuring in-
strument.
6. Install the device in the switchboard on the
TH35 rail.
7. Connect the wires to the terminals in ac-
cordance with the wiring diagram.
8. Switch on the power supply.
9. Do not touch connecting terminals of the
meter with bare hands, metal objects, non-
insulated wire or other conductive object,
because it poses a risk of electric shock,
which can result in injuries, serious injuries
or death.
10. Maintenance and repairs of the meter can
becarriedout only byqualiedpersonnel
with valid authorizations.
11. The meter should be protected against fall
and mechanical impacts, that may cause
damage of precise components inside it
and have adverse effect on accuracy of the
measurements.
NOTE: Using pulse output (terminals 22
and 23) you should apply additional sup-
ply voltage within the range 5 ÷ 27 V DC
through a resistor R (470 Ω ÷ 1 kΩ) limiting
the value of the current.
