ControlNet Daughtercard 3

ATTENTION

Environment and Enclosure

This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC
publication 60664-1), at altitudes up to 2000 meters without derating.

This equipment is considered Group 1, Class A industrial equipment
according to IEC/CISPR Publication 11. Without appropriate
precautions, there may be potential difficulties ensuring electromagnetic
compatibility in other environments due to conducted as well as radiated
disturbance.

This equipment is supplied as “open type” equipment. It must be
mounted within an enclosure that is suitably designed for those specific
environmental conditions that will be present and appropriately designed
to prevent personal injury resulting from accessibility to live parts. The
interior of the enclosure must be accessible only by the use of a tool.
Subsequent sections of this publication may contain additional
information regarding specific enclosure type ratings that are required to
comply with certain product safety certifications.

NOTE: See NEMA Standards publication 250 and IEC publication
60529, as applicable, for explanations of the degrees of protection
provided by different types of enclosure. Also, see the appropriate
sections in this publication, as well as the Allen-Bradley publication
1770-4.1 (“Industrial Automation Wiring and Grounding Guidelines”),
for additional installation requirements pertaining to this equipment.

ATTENTION

Preventing 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.

• If available, use a static-safe workstation.

• When not in use, store the equipment in appropriate static-safe

packaging.

European Hazardous Location Approval

European Zone 2 Certification
(The following applies when the product bears the EEx Marking.)

This equipment is intended for use in potentially explosive atmospheres as defined by
European Union Directive 94/9/EC.

The LCIE (Laboratoire Central des Industries Electriques) certifies that this equipment has
been found to comply with the Essential Health and Safety Requirements relating to the
design and construction of Category 3 equipment intended for use in potentially explosive
atmospheres, given in Annex II to this Directive. The examination and test results are
recorded in confidential report No. 28 682 010.

Compliance with the Essential Health and Safety Requirements has been assured by
compliance with EN 50021.

IMPORTANT

• This equipment is not resistant to sunlight or other sources of UV
radiation.

• The secondary of a current transformer shall not be open-circuited
when applied in Class I, Zone 2 environments.

• Equipment of lesser Enclosure Type Rating must be installed in an
enclosure providing at least IP54 protection when applied in Class I,
Zone 2 environments.

• This equipment shall be used within its specified ratings defined by
Allen-Bradley.

• Provision shall be made to prevent the rated voltage from being
exceeded by transient disturbances of more than 40% when applied
in Class I, Zone 2 environments.

North American Hazardous Location Approval

The following information applies when operating
this equipment in hazardous locations:

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.

6 ControlNet Daughtercard

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.

• If you insert or remove the card while host 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.

About the Daughtercards

The network daughtercard architecture defines a common
hardware and software interface that several different
network interface cards will support. This allows products
that have been designed to support the network
daughtercard option to support several different Rockwell
Automation networks.

About the ControlNet Daughtercard

You can install the 1788-CNC or -CNCR ControlNet daughtercard in any host device that

supports the ControlNet daughtercard.

Every ControlNet network requires at least one module that is able to store parameters and
configure the network with those parameters upon start-up. This module is called a ‘keeper’
since it keeps the network configuration.

Any 1788-CNC or -CNCR card can keep the network parameters at any legal node address
(01 to 99). Multiple devices on any one network can act as the network keeper. Each device
capable of being the network keeper acts to back up the current keeper. This backup function
is automatic and requires no action on your part.

IMPORTANT

(1)

The host device must provide a suitable power source per the restrictions in the specifications table.

Publication 1788-IN002C-EN-P - April 2004

On the 1788-CNC or -CNCR card, the non-volatile keeper data is erased
when a firmware update is performed.
