replacement whilst work is performed. If isolation is provided by a switch, the switch must
conform to the requirements of IEC 947-1 and IEC 947-3 or equivalent.
•Over-current protection is not provided by the equipment and must be provided as part of the
building installation. For the domestic supply the maximum over-current device rating is 100A
at 415V AC, conforming to the requirements of BS1361 or equivalent.
•Only suitable trained and qualied personnel shall be allowed to work on the equipment. Local

short-circuits.
•The meters must only be cleaned whilst disconnected and with a dry cloth without solvent and
on no account be cleaned with running water or with high-pressure devices. Penetrating water
can cause internal short-circuits.
•A terminal cover protects inadvertent exposure to the meter tail connections and must be
