UL, C-UL ControlNet Ex System Requirements
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.
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.
WARNING:
Substitution of components may impair intrinsic safety.
AVERTISSEMENT:
La substitution de composant peut compromettre la
securite intrinseque.
If fiber optic cable is provided with a metal shield, it must be connected
to a dedicated intrinsic safety ground in the nonhazardous location and tied
back in the hazardous location or be connected to a ground in the hazardous
location and tied back in the nonhazardous location.
The glass fiber must have a minimum diameter of 6
μ
m.
