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 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 D5038 series 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 group. See parameters indicated in the table below:

For installations in which both the Ci and Li of the Intrinsically Safe apparatus exceed 1 % of the Co and Lo parameters of the Associated Apparatus (excluding the cable),
then 50 % of Co and Lo parameters are applicable and shall not be exceeded
(50 % of the Co and Lo become the limits which must include the cable such that Ci C cable
≤
50 % of Co and Li L cable
≤
50 % of Lo). The reduced capacitance of the external circuit (including cable) shall not be greater than 1
μ
F for Groups I, IIA, IIB and 600 nF for
Group IIC. If the cable parameters are unknown, the following value may be used: Capacitance 180pF per meter (60pF per foot), Inductance 0.60µH per meter (0.20µH per foot).
