• Do not connect or disconnect components unless power

has been switched off or the area is known to be non-hazardous.

• This product must be installed in an enclosure. All cables

connected to the product must remain in the enclosure or be protected by conduit or other means.

• All wiring must comply with N.E.C. article 501-4(b).

Environnements dangereux

Cet équipement est conçu pour être utilisé dans des environnements de Classe 1, Division 2, Groupes A, B, C, D ou non dangereux. La mise en garde suivante s’applique à une utilisation dans des environnements dangereux.

Publication 1769-IN060C-EN-P - May 2002

DANGER D’EXPLOSION

• La substitution de composants peut rendre cet équipement

impropre à une utilisation en environnement de Classe 1, Division 2.

• Ne pas remplacer de composants ou déconnecter

l'équipement sans s'être assuré que l'alimentation est coupée et que l'environnement est classé non dangereux.

• Ne pas connecter ou déconnecter des composants sans

s'être assuré que l'alimentation est coupée ou que l'environnement est classé non dangereux.

• Ce produit doit être installé dans une armoire.

ATTENTION

Module Installation

The 1769-SDN module is suitable for use in an industrial environment when installed in accordance with these instructions. Specifically, this equipment is

intended for use in clean, dry environments (Pollution Degree 2 circuits not exceeding Over Voltage Category II

(2)

(IEC 60664-1).

Prevent Electrostatic Discharge

Electrostatic discharge can damage integrated circuits or semiconductors if you touch bus connector pins. Follow these guidelines when you handle the module:

• Touch a grounded object to discharge static potential.

• Wear an approved wrist-strap grounding device.

• Do not touch the bus connector or connector pins.

• Do not touch circuit components inside the module.

• If available, use a static-safe work station.

• When not in use, keep the module in its static-shield box.

(1)

) and with

(3)

(1)

Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a temporary conductivity caused by condensation shall be expected.

(2)

Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are controlled and do not exceed the impulse voltage capability of the product’s insulation.

(3)

Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.

Publication 1769-IN060C-EN-P - May 2002

Remove Power

ATTENTION

Compact I/O DeviceNet Scanner Module 7

Remove power before removing or inserting this module. When you remove or insert a module with power applied, an electrical arc may occur. An electrical arc can cause personal injury or property damage by:

• sending an erroneous signal to your system’s field devices,

causing unintended machine motion

• causing an explosion in a hazardous environment

Electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance.

8 Compact I/O DeviceNet Scanner Module

System Planning

Consider the following when planning your system:

• The scanner can communicate with up to 63 DeviceNet devices.

• The scanner, as a master, can own up to 63 slave I/O nodes.

• The scanner can simultaneously be a master and be a slave owned by

another DeviceNet master.

• A 1769-ECR (right end cap) or 1769-ECL (left end cap) is required to

terminate the end of the Compact I/O bus.

• Each bank of Compact I/O must have its own power supply (a MicroLogix

1500 acts as the power supply for modules directly connected to it).

• A Compact I/O power supply, or MicroLogix 1500 Base Unit, has limits in

the amount of +5V dc and +24V dc current it can supply to modules in its I/O bank. These limits depend on the catalog number (e.g. 1769-PA2) of the supply. A bank of modules must not exceed the current limits of the I/O bank power supply or MicroLogix 1500 Base Unit.

Refer to the Compact 1769 Expansion I/O Power Supplies Installation Instructions, publication 1769-5.14 or the MicroLogix 1500 User Manual, publication 1764-UM001A-EN-P.

• The scanner has a distance rating of four, therefore the scanner must be

within four modules of the I/O bank’s power supply.

• Determine the DeviceNet baud rate based on standard DeviceNet

considerations.

• Consider the number of words of I/O data the host controller supports.

For more information on planning your DeviceNet network, refer to the DeviceNet Cable System Planning and Installation Manual, publication DN-6.7.2.
