In the system safety analysis, always check the Hazardous Area/Hazardous Locations devices to conform with the related system documentation, if the device is Intrinsically Safe check
its suitability for the Hazardous Area/Hazardous Locations and gas group encountered and that its maximum allowable voltage, current, power (Ui/Vmax, Ii/Imax, Pi/Pi) are not exceeded
by the safety parameters (Uo/Voc, Io/Isc, Po/Po) of the PSD1001 Associated Apparatus connected to it. Also consider the maximum operating temperature of the field device, check that
added connecting cable and field device capacitance and inductance do not exceed the limits (Co/Ca, Lo/La, Lo/Ro) given in the Associated Apparatus parameters for the effective gas
group. See parameters on
enclosure side and the ones indicated in the table below:
