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) indicated in this manual and enclosure side of the PSD1004 Intrinsically Safe Apparatus connected to it.

When checking the power matching 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 / La/Ra) given in the Associated Apparatus parameters for the effective gas group (see parameters on enclosure side).

If the cable parameters are unknown, the following value may be used: Capacitance 60 pF per foot (180 pF per meter), Inductance 0.20 mH per foot (0.60 mH per meter).
Note that for the PSD1004 the system analysis must be performed for the input and also for the output connection.
Storage
If after an incoming inspection the unit is not installed directly on a system (parts for spare or expansion with long storage periods) it must be conveniently stocked. Stocking area
characteristics must comply with the following parameters:
Temperature –10 to +30 °C the – 40 to +80 °C in the data sheet is meant for limited periods, mainly to arrange for air transport.
Humidity 0 to 70%
long period high humidity affects the package integrity and promotes corrosion of metal parts.
Vibration:
no vibration should be perceivable in the stocking area to avoid loosening of parts or fatigue ruptures of components terminals.
Pollution:
presence of pollutant or corrosive gases or vapors must be avoided to prevent corrosion of conductors and degradation of insulating surfaces.
Disposal (Waste Electrical and Electronic Equipment)
This marking shown on the products indicates that it should not be disposed with other wastes at the end of its working life. It may content hazardous substances for the health and the
environment, to prevent possible harm from uncontrolled waste disposal, please separate this equipment from other types of wastes and recycle it responsibly to promote the sustainable
reuse of material resources. Users should contact either the supplier or their local government office for details of where and how they can take this equipment for environmentally safe
recycling. This product should not be mixed with other commercial wastes for disposal.
