Do not touch live parts
Dangers can arise from live electrical installations to which the meters are
connected. Touching live parts is dangerous to life. All safety information
should therefore be strictly observed.
Before installation, the meter should be examined to check that the case
and seals are intact. Should any damage be evident, the problem must be
reported to a Landis+Gyr sales representative as soon as possible.
Dangerous voltage on conductors
The connecting wires at the place of installation must not be live when
fitting the meter. Touching live parts is dangerous to life. The mains fuses
should be removed and kept in a safe place until work is completed, so that
they cannot be replaced by anyone unnoticed.
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.
No over current protection and automatic disconnection
As the meter has no internal overcurrent protection and no method of
disconnection from the mains, this must be provided by the end installation.
Protect supply control switch against overcurrent
In case the meter has a supply control switch: as the supply control switch
is not equipped with a thermal and/or short circuit protection device, it
needs to be protected with an external fuse or oversupply control switch.
