The entity concept allows interconnection of intrinsically safe apparatus
with associated apparatus not specifically examined in combination as a
system when the approved values of V
oc
and I
sc
or V
t
and I
t
of the associated
apparatus are less than or equal to V
max
and I
max
of the intrinsically safe
apparatus and the approved values of C
a
and L
a
of the associated apparatus
are greater than C
i
+ C
cable
and L
i
+ L
cable
respectively for the intrinsically safe
apparatus.
Simple apparatus is defined as a device which neither generates nor stores
more than 1.2V, 0.1 A, 20 μ J, or 25 mW.
Wiring methods must be in accordance with the National Electric Code,
ANSI/NFPA 70, Article 504 and 505 or the Canadian Electric Code CSA
C22.1, Part 1, Appendix F. For additional information refer to ANSI/ISA
RP12.6.
This module, 1797-OE8, must be used with terminal base 1797-TB3 or
1797-TB3S.
Terminals 2, 3, 6, 7, 10, 11, 14, 15, 19, 20, 23, 24, 27, 28, 31, 32, 36 to 39,
and 46 to 49 shall not be connected.
WARNING: Substitution of components may impair intrinsic safety.
AVERTISSEMENT: La substitution de composant peut compromettre la
securite intrinseque.
