Iskra ME382 (& MT382) Smart Meter –Installer Instructions
Although installing this smart meter only involves connecting four wires, we recommend that it should only
be carried by a qualified electrician. However, the direct replacement of an existing meter, outside of a
special area, does not currently need notification to Building Control by a Competent Person under Part P.
The users may occasionally need to push the blue button and see the LCD screen –so if possible position
the meter at eye level or below in an accessible place.
If required, please make a note of any credit on the meters that you are replacing so
that it can be transferred to the new meter.
The supply circuit must be disconnected during the installation, and only re-energised once all the wiring
connections are secure and the terminal cover is installed. Please also check that there is electricity in the
flat downstream of the meter after the installation.
These meters are remotely read and credited by the tenant and if they were to be installed on the wrong
circuit then that tenant would be crediting his neighbour’s meter. So it is really important that the
correct meter is installed in the correct location. The meters are dispatched with the
location printed on the packaging box, and there is also a meter serial number which can be used to match
the correct location by the labels. (If the wrong meter has accidentally been installed in the wrong location
please tell us so that we can correct it remotely).

To install the ME382 –single phase meter simply connect the four cables: live input and output, and
neutral input and output. The MT382 is a three phase meter with eight cables: i.e. live input and outputs
for each of the three phase.
Once the electricity is reconnected, the meter should automatically power up. Please look for a
triangular flag above SQ on the LCD screen to check that the meter has adequate signal
quality.
If the flag is on, then there is a high mobile network signal quality. If the flag is not shown, or is flashing,
then there is no or low signal quality. To communicate effectively with our systems, you may then need an
external antenna which we will supply. The REG flag should also be solid to indicate that the SIM
card is registered.
The meter is now ready to be activated –please phone [phone] to directly tell Meterix who
manage our communications to check that mobile network connections are working. Meterix can then tell
us to commence our back-end processes which are needed to commission the meter.
Stick the label giving the top-up details on the meter as shown –you may also wish to stick further
stickers in a readily visible location for your tenants –e.g. the front of the meter cupboard. Please ensure
that the stickers match the address and serial number.
Finally, give the instruction card to the tenant ensuring
that it also has the correct address and serial number (you may need
to stick a label in the blank spot on the top of the instruction leaflet).
After installation, electricity will flow freely through the meter until
all the emergency credit has been used up, so tenants will have a
couple of days in which to make the initial top-up.
In case of any problem you can contact us on 01234 484444 or
Meterix on 01803 500 850 for technical difficulties. Out of hours
you can contact Gary Wernick on 07956 391143 or Dan Homer on
07730 129990.
