DANGER!
Supply voltage!
Contact with non-insulated parts carrying supply voltage involves the risk of an electric shock resulting in
injuries and death.
The connection to the electric mains and the corresponding protective equipment must comply with the legal
provisions in force at the place of installation of the METPOINT
be carried out by specialists who are qualified accordingly.
Make sure that no parts of the measuring devices are energised and that the devices cannot be connected
with the electric supply mains during service measures.
DANGER!
Missing earth connection!
When the earth connection (protective earth) is missing, there is the risk in the event of malfunction, that
contactable, conductive components may carry supply voltage. Touching of such parts leads to an electric
shock with injuries and death.
It is imperative to connect the plant to earth or to connect the protective conductor according to the
regulations.
Do not use plug adapters at the power plug.
Have the power plug replaced by qualified skilled persons, if required.
