Removal and Insertion Under Power (RIUP) Capability
Ethernet Network Communications Connections
North American Hazardous Location Approval
WARNING When you insert or remove the module while backplane power is on, an electrical
arc can occur. This could cause an explosion in hazardous location installations. Be
sure that power is removed or the area is nonhazardous before proceeding. Repeated
electrical arcing causes excessive wear to contacts on both the module and its
mating connector. Worn contacts may create electrical resistance that can affect
module operation.
WARNING If you connect or disconnect the communications cable with power applied to this
module or any device on the network, an electrical arc can occur. This could cause
an explosion in hazardous location installations. Be sure that power is removed or
the area is nonhazardous before proceeding.
The following information applies
when operating this equipment in
hazardous locations: Informations sur l’utilisation de cet
équipement en environnements
dangereux:
Products marked “CL I, DIV 2, GP A,
B, C, D” are suitable for use in Class
I, Division 2 Groups A, B, C, D,
hazardous locations and
nonhazardous locations only. Each
product is supplied with markings on
the rating nameplate indicating the
hazardous location temperature code.
When combining products within a
system, the most adverse temperature
code (lowest “T” number) may be
used to help determine the overall
temperature code of the system.
Combinations of equipment in your
system are subject to investigation by
the local authority having jurisdiction
at the time of installation. Les produits marqués “CL I, DIV 2, GP A,
B, C, D” ne conviennent qu’à une
utilisation en environnements de Classe I
Division 2 Groupes A, B, C, D dangereux
et non dangereux. Chaque produit est livré
avec des marquages sur sa plaque
d’identification qui indiquent le code de
température pour les environnements
dangereux. Lorsque plusieurs produits sont
combinés dans un système, le code de
température le plus défavorable (code de
température le plus faible) peut être utilisé
pour déterminer le code de température
global du système. Les combinaisons
d’équipements dans le système sont
sujettes à inspection par les autorités
locales qualifiées au moment de
l’installation.
