Publication 1794-IN101B-EN-P - June 2004
North American Hazardous Location Approval
The following adapters are North American Hazardous Location approved:
1794-ACN15/C, -ACN15K/C, -ACNR15/C and -ACNR15K/C.
ControlNet Adapter, Cat. No. 1794-ACN15 and 1794-ACNR15
1794-ACN15(K) and 1794-ACNR15(K) Series C, Firmware 4.1, of the FLEX
I/O ControlNet Single and Redundant adapters allow the 1794-ACN15(K)
and 1794-ACNR15(K) to talk with the 1794-OB32 module. (Previous versions
of the 1794-ACN15 and -ACNR15 adapters would not properly communicate
with the new 1794-OB32 module.)
This version of the 1794-ACN15(K) and -ACNR15(K) adapters changed how
the adapter firmware is displayed in RSNetworx for ControlNet (Rev 3.0 and
earlier). Previous versions of the adapters displayed an alpha for the firmware
version
(C/F = major firmware revision C [3] , minor firmware revision F [6] ). This
current release will display the firmware revision numerically. (Ex. 4.1 = major
firmware revision 4, minor firmware revision 1). The Series remains
unchanged as Series C.
Customers using RSNetworx for ControlNet (Revision 3.21 or later) will see all
current and previous versions of 1794-ACN15 and -ACNR15 adapter
firmware displayed numerically.
Installing Your ControlNet Adapter Module
Mounting on a DIN rail before installing the Terminal Base Units
1. Position the ControlNet adapter module (A) on a 35 x 7.5mm DIN
rail (B) at a slight angle.
2. Hook the lip on the rear of the adapter onto the top of the DIN rail,
and rotate the adapter module onto the rail.
3. Press the adapter module down onto the DIN rail until flush. Locking
tab C will snap into position and lock the adapter module to the DIN
rail.
4. If the adapter module does not lock in place, use a screwdriver or
similar device to move the locking tab down while pressing the
adapter module flush onto the DIN rail, and release the locking tab to
lock the adapter module in place. If necessary, push up on the locking
tab to lock.
5. Connect the adapter wiring as shown under “Wiring” later in this
document.
Panel/Wall Mounting
If mounting this adapter to a panel or wall, refer to publication 1794-5.13,
“Panel Mounting Kit, Cat. No. 1794-NM1.”
Mounting (or Replacing) the Adapter on an Existing System
1. Disconnect any wiring jumpered to the adjacent terminal base.
2. Disconnect the BNC connector(s) from the front of the adapter
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.
EXPLOSION HAZARD
• Do not disconnect equipment
unless power has been removed or
the area is known to be
nonhazardous.
• Do not disconnect connections to
this equipment unless power has
been removed or the area is known
to be nonhazardous. Secure any
external connections that mate to
this equipment by using screws,
sliding latches, threaded
connectors, or other means
provided with this product.
• Substitution of components may
impair suitability for Class I,
Division 2.
• If this product contains batteries,
they must only be changed in an
area known to be nonhazardous.
RISQUE D’EXPLOSION
• Couper le courant ou s’assurer que
l’environnement est classé non
dangereux avant de débrancher
l'équipement.
• Couper le courant ou s'assurer que
l’environnement est classé non
dangereux avant de débrancher les
connecteurs. Fixer tous les connecteurs
externes reliés à cet équipement à
l'aide de vis, loquets coulissants,
connecteurs filetés ou autres moyens
fournis avec ce produit.
• La substitution de composants peut
rendre cet équipement inadapté à une
utilisation en environnement de Classe
I, Division 2.
• S’assurer que l’environnement est
classé non dangereux avant de changer
les piles.

ATTENTION
During mounting of all devices, be sure that all
debris (metal chips, wire strands, etc.) is kept from
falling into the module. Debris that falls into the
module could cause damage on power up.
WARNING
If you connect or disconnect the ControlNet cable with
power applied to this module or any device on the network,
an electrical arc can ocur. This could cause an explosion in
hazardous installations. Be sure that power is removed or
the area is nonhazardous before proceeding.
