Safety Regulations

© Landis+Gyr
The following safety regulations must be observed at all times:
•
The meter connections must be disconnected from all voltage sources
during installation or when opening.
•
Contact with live parts can be fatal. The main fuse should, therefore,
be removed and kept in a safe place until the work is completed so
that other persons cannot replace it unnoticed.
•
Local safety regulations must be observed. Only technically qualified
and appropriately trained personnel are authorised to install the
meters.
•
Protection earth connection must not be switched with the disconnector.
•
Only "useful" tools have to be used. This means a screw driver has to
have the correct size for the screws and the metallic part of a screw
driver has to 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 never be cleaned under running water or with
compressed air. Water ingress can cause short-circuits.
