depending on the version
Taking into consideration electromagnetic interference it is recommended to use shielded
conductors for the connection of input and output signals. The power supply must be connected by
means of a two-wire conductor with a suitable cross-section ensuring its protection by means of an
installation fusible cut-out, in case of a short-circuit.
The requirements concerning the supply cable are regulated by EN 61010-1 p.6.10 standard.
