Hazardous Area Specific Guidelines:
1. Do not open unit when energized.
2 .Do not disconnect equipment unless area is
known to be non-hazardous.

cally examined in such combination. The crite-
ria for interconnection is that the voltage and
current which intrinsically-safe apparatus can
receive and remain intrinsically-safe, consider-
ing faults, must be equal to or greater than the
voltage and current levels which can be deliv-
)
ered by the associated apparatus, considering
L
faults and applicable factors. In addition, the
maximum unprotected capacitance and induc-
tance of the IS apparatus, including the inter-
connecting wiring, must be equal or less than
the capacitance and inductance which can be
safely connected to the associated apparatus.
The "entity parameters" were broadened to
allow IXLdp users the freedom to apply the
IXLdp into a wider array of applications.
Additionally, the inclusion of a "nonincendive"
rating gives our customers the ability to
choose an intrinsically safe barrier from any
barrier manufacturer meeting the below ratings.
