In the system safety analysis, always check the Hazardous Area devices to conform with the related system documentation, if the device is Intrinsically Safe check its suitability for the
Hazardous Area 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 D1010-05* 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 gas group.

When used with separate powered intrinsically safe devices, check that maximum allowable voltage, current (Ui/Vmax, Ii/Imax) of the D1010-05* Associated Apparatus are not exceeded
by the safety parameters (Uo/Voc, Io/Isc) of the Intrinsically Safe device, 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).
If the cable parameters are unknown, the following value may be used: Capacitance 60pF per foot (180pF per meter), Inductance 0.20µH per foot (0.60µH per meter).
