Safety regulations

© Landis+Gyr
The following safety regulations must be observed at all times:

This meter does not contain a disconnection device. Means for discon-
nection from the supply must be provided as part of the building instal-
lation. Do not work on the equipment unless the supply is disconnected.
If disconnection is done by removal of fuses or other cut-outs, the re-
moved disconnection devices must be kept secure from replacement
while work is performed. If disconnection is provided by a switch, the
switch shall conform to the requirements of IEC 947-1 and IEC 947-3
or equivalent.

This meter does not contain an overcurrent protection device. Over-
current protection must be provided as part of the building installation.
Maximum overcurrent device rating is 100 A at 415 V, conforming to
the requirements of BS1361 or equivalent.

This meter has a maximum current rating of 100 A and a single fault
overload rating of 145 A. The meter terminals accept cables up to 35
2
mm . Use with smaller diameter cables without corresponding derating
of the mains fuse may degrade the meter.

Local safety regulations must be observed and shall take precedence
over these regulations in the event of a conflict. Only technically quali-
fied and appropriately trained personnel are authorised to install the
meters.

Only appropriate tools shall be used for the job. This means, e.g. that
the screwdriver must be of the correct size for the screws, and the
handle of the screwdriver must be insulated.

The meters must be held securely during installation. They can cause
injuries if dropped.

Meters that have been dropped must not be installed, even if no
damage is apparent, but must be returned to the service and repair
department (or the manufacturer) for testing. Internal damage may
result in malfunctions or short-circuits.

The meters must not be cleaned under running water or with
compressed air. Water ingress can cause short-circuits.

The meter terminal cover should be secured in place before any load
is supplied.
Risks of not covering the intimate communications hub interface
If the meter is supplied without a manufacturer supplied intimate
communications hub interface (ICHI) cover, there are potential safety risks
of installing the product and not fitting a cover, including accidental contact
with an energy source. Such a product should not be installed without an
appropriate cover fitted over the ICHI connector (being a separately
supplied ICHI cover or a communications hub) and the manufacturer shall
not be liable for any consequences associated with the failure to fit such a
cover.
