A. For intrinsically safe operation (recognized by a BLUE COVER),
intrinsic safety barrier selection, cable parameters and power supply
limits must be in accordance with the entity parameters shown on
drawing.
B. If the area classification is a Division 2 or Zone 2, a barrier is not
required. Note however when intrinsic safe apparatus is used without
barrier, this apparatus may
NOT
be considered as intrinsically safe.
This is because input protection diodes may be damaged without
affecting normal operation. It is the customers’ responsibility to clearly
mark the apparatus when intrinsic safety is no longer valid.
C. Connect the IS Alarm as shown in Figures 2-2 and 2-3.
