Publication 1794-IN087C-EN-P - July 2005

North American Hazardous Location Approval

PROFIBUS Adapter, Cat. No. 1794-APB Series B

Installing Your Adapter Module

Mounting on a DIN rail before installing the Terminal Base Units

1. Position the 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 “Connecting Wiring”

later in this document.

Remove debris wrapper before applying power to the module.

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. Remove the PROFIBUS connector from the front of the adapter.

2. Disconnect any wiring jumpered to the adjacent terminal base.

3. Open the module latching mechanism and remove the module from

the base unit to which the adapter will be attached.

4. Push the flexbus connector toward the right side of the terminal base

to unplug the backplane connection.

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.

WARNING

AVERTISSEMENT

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 PROFIBUS 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.
