LEM-30 energy meter with a backlit
display, is used to monitor the three-
phase electricity consumption in com-
mercial and industrial applications.
It measures and displays the kWh. It is
possible to connect a measuring device,
due to an additional impulse output. The
meter can be mounted in distribution
boards or can be connected to an exter-
nal power supply source.
The device is designed
for three-phase installa-
tion and must be installed
in accordance with stand-
ards valid in a particu-
lar country. The device
should be connected
according to the details included in this
operating manual. Installation, connec-
tion and control should be carried out by
a qualified electrician staff, who act in
accordance with the service manual and
the device functions.
Disassembling of the device is equal
with a loss of guarantee and can cause
electric shock. Before installation make
sure the connection cables are not under
voltage. The cruciform head screwdriver
4 mm should be used to install the device.
Improper transport, storage, and use of
the device influence its wrong function-
ing. It is not advisable to install the device
in the following cases: if any device part
is missing or the device is damaged or
deformed. In case of improper function-
ing of the device contact the producer.
CAUTION!
The symbol means selective
collecting of electrical and
electronical equipment. It
is forbidden to put the used
equipment together with other
waste.
