Environment and Enclosure
ATTENTION: This equipment is intended for use in overvoltage Category II
applications (as defined in IEC 60664-1), at altitudes up to 2000 m (6562 ft)
without derating.
This equipment is considered Group 1, Class A industrial equipment according
to IEC/CISPR 11. Without appropriate precautions, there may be difficulties
with electromagnetic compatibility in residential and other environments due to
conducted and radiated disturbances.
This equipment is supplied as enclosed equipment. It should not require
additional system enclosure when used in locations consistent with the
enclosure type ratings stated in the Specifications section of this publication.
Subsequent sections of this publication may contain additional information
regarding specific enclosure type ratings, beyond what this product provides,
that are required to comply with certain product safety certifications.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, Rockwell
Automation publication 1770-4.1
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the
degrees of protection provided by different types of enclosure.
Prevent Electrostatic Discharge
ATTENTION: 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.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in use.

About the Modules
The ArmorPOINT I/O family consists of modular I/O modules. The sealed IP67
housing of these modules requires no enclosure. Note that environmental requirements
other than IP67 may require an additional appropriate housing. I/O connectors are sealed
M12 style. The mounting base ships with the module. The 1738-OE2CM12 module is
shown here.

Mount the I/O Base
To mount the base on a wall or panel, use the screw holes provided in the base.
ATTENTION: The ArmorPOINT I/O module must be mounted on a grounded
metal mounting plate or other conductive surface.
A mounting diagram for the ArmorPOINT base with adapter is shown here.
Install the mounting base as follows:
1. Lay out the required points as shown above in the drilling dimension diagram.
2. Drill the necessary holes for M4 (#8) machine or self-tapping screws.
3. Mount the base using M4 (#8) screws.
4. Ground the system using the ground lug connection. The ground lug connection
is also a mounting hole.

Install the Module
To install the analog output module, proceed as follows:
1. Using a bladed screwdriver, rotate the keyswitch on the mounting base clockwise
until the number 4 aligns with the notch in the base.
2. Position the module vertically above the mounting base. The module bridges
two bases.
3. Push the module down until it engages the latching mechanism. You hear a
clicking sound when the module is properly engaged. The locking mechanism
locks the module to the base.
Remove the Module from the Mounting Base
To remove the module from the mounting base:
1. Insert a flat blade screwdriver into the slot of the orange latching mechanism.
2. Push the screwdriver toward the I/O module to disengage the latch. The module
lifts up off the base.
3. Pull the module off the base.

Analog modules have earth grounded metal rings. This should be
considered when choosing shielded cables and grounding techniques.
ATTENTION: Make sure all connectors and caps are securely tightened to
properly seal the connections against leaks and maintain IP enclosure type
requirements.

Communicate with the Module
I/O messages are sent to (consumed) and received from (produced) the ArmorPOINT
modules. These messages are mapped onto the processor’s memory. The ArmorPOINT
analog output modules produce 2 Bytes of input data (scanner Rx – fault status). They
consume 4 Bytes of output data (scanner Tx).
