isolation device for the instrument.
Cables and circuits must fulfil the isolation requirements and

conform to, for example, IEC 60227 or IEC 60245.
Do not connect circuits simultaneously with extra-low voltage
■
circuits, or with safety extra-low voltage circuits (SELV) or
protected extra-low voltage circuits (PELV).
The earthing terminal is not connected and therefore it does not
