XM-12X Dynamic Measurement Modules
European Hazardous Location Approval
ATTENTION: The serial communication port is intended only for temporary local-programming purposes only and is not
intended for permanent connection:
• The serial cable and power connections are not to exceed 3.0 m (9.84 ft).
• This product is intended to be mounted to a well-grounded mounting surface such as a metal panel or DIN rail. For DIN rail
mounting, use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail materials (for
example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.) and use end-anchors appropriately.
• Do not remove or replace a terminal base unit while power is applied. Interruption of the backplane can result in
unintentional operation or machine motion.
• This module is designed so you can remove and insert it under power. However, when you remove or insert the module with
power applied, I/O attached to the module can change states due to its input/output signal changing conditions. Take
special care when using this feature.
IMPORTANT Install the overlay slide label to protect the serial connector and electronics when the serial port is not in use.
The following applies when the product bears the Ex Marking
This equipment is intended for use in potentially explosive atmospheres as defined by European Union Directive 94/9/EC and 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
Zone 2 potentially explosive atmospheres, given in Annex II to this Directive.
Compliance with the Essential Health and Safety Requirements has been assured by compliance with EN 60079-0, EN 60079-15 and EN 60079-11.
WARNING: The installation of the XM-12x module includes the following warnings:
• This equipment must be mounted in an ATEX-certified enclosure with a minimum ingress protection rating of at least IP54
(as defined in IEC60529), and used in an environment of not more than Pollution Degree 2 (as defined in IEC 60664-1)
when applied in Zone 2 environments. The enclosure must have a tool-removable cover or door.
• This equipment must be used within its specified ratings defined by Rockwell Automation.
• For products with I/O or power connections: Provision must be made to prevent the rated voltage from being exceeded by
transient disturbances of more than 140% of the rated voltage when applied in Zone 2 environments.
• This equipment must be used only with ATEX-certified Allen-Bradley terminal bases.
• Secure any external connections that mate to this equipment by using screws, sliding latches, threaded connectors, or
other means provided with this product.
• Do not disconnect equipment unless power has been removed or the area is known to be nonhazardous. Connection of the
modules to barriers and/or sensors located in dangerous areas is the responsibility of the user.
• The XM-120, XM-121, XM-122, and XM-123 modules must be installed in accordance with specification control sheets
48178-HAZ and 48179-HAZ.
