Figure 3 Installation configuration 1
This configuration allows the four channel analogue receiver to be located wholly within the
hazardous area and the connection of intrinsically safe circuits to its various ports. The
analogue outputs can be driven from a single or four different intrinsically safe sources
because of the segregation between the four analogue output channels. For the same
reason the power supply port can be driven from the same source as the analogue outputs
or from an entirely different intrinsically safe source without the need for an assessment of
voltage or current addition.

Table 6 Installation configuration 1 entity parameters
The table above lists the entity parameters awarded to the receiver by its certification for
this configuration, these parameters would need to be taken into account when conducting
an installation assessment in accordance with IEC60079-25.
As always, careful attention should be paid to the segregation of wiring in this configuration
as incorrectly segregated wiring could negate the segregation and safety of the receiver.
