1.3 Safety
Instructions
The following safety instructions must be observed at all times:
The meter connections must not be under voltage during installation or
when opening. Contact with live parts is dangerous to life. The relevant
main fuses should therefore be removed and kept in a safe place until
the work is completed, so that other persons cannot replace them
unnoticed.
Local safety regulations must be observed.
Protection earth connection must not be switched with the supply
control switch.
Only appropriate tools may 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 which have fallen, must not be installed, even if no damage is
apparent, but must be returned for testing to the service and repair
department responsible (or the manufacturer). Internal damage can
result in functional disorders or short-circuits.
The meters must on no account be cleaned with running water or with
compressed air devices. Water penetrating can cause short-circuits.
1.4 Radio
Interference
Possible radio interference in residential environments
This meter is normally a class B product. In combination with some
communication modules, it can become a Class A product. In a domestic
environment, this may then cause radio interference, in which case the user
may be required to take adequate measures
.
