ControlNet Adapter, 1794-ACN15, 1794-ACN15K, 1794-ACNR15,
1794-ACNR15XT, Series D
1794-ACN15(K), 1794-ACNR15(XT) Series D, Firmware Revision 10.2, of the
FLEX I/O ControlNet Single and Redundant adapters function as drop-in
replacements for the series C adapters and continue to support 32-bit modules and
numerical display of the firmware revision in RSNetWorx for ControlNet
(Revision 3.21 or later).
Do not remove or replace an adapter module while power is
applied. Interruption of the backplane can result in unintentional
operation or machine motion.
To reduce susceptibility to noise, power communications adapter
modules and I/O modules from separate power supplies.
To comply with the CE Low Voltage Directive (LVD), this equipment
must be powered from a source compliant with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage
(PELV).
Prevent Electrostatic Discharge
This equipment is sensitive to electrostatic discharge, which can
cause internal damage and affect normal operation. Follow these
guidelines when you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging
when not in use.
For Class I Division 2 applications, use only Class I Division 2 listed
or recognized accessories and modules approved for used within the
1794 platform.

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.
