Instructions specific to hazardous area installations
• Refer to
Under the entity evaluation concept, SITRANS LR250 has the following characteristics:
(input voltage) U
i
(input current) I
i
(input power) P
i
(internal capacitance) Ci
(internal inductance) Li
Entity Concept:
The Entity Concept allows interconnection of Intrinsically Safe apparatus to associated
apparatus not specifically examined in such combination. The criteria for interconnection is
that the voltage and current which Intrinsically Safe apparatus can receive and remain
Intrinsically Safe, considering faults, must be equal to or greater than the output voltage (Uo)
and output current (Io) levels which can be delivered by the associated apparatus, considering
faults and applicable factors. In addition, the maximum unprotected capacitance (Ci) and
Inductance (Li) of the Intrinsically Safe apparatus, including interconnecting wiring, must be
equal to or less than the capacitance and inductance which can be safely connected to
associated apparatus.
