Environment and Enclosure
This equipment is intended for use in overvoltage Category II applications (as
defined in IEC publication 60664-1), at altitudes up to 2000 meters (6562 ft)
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 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, Allen-Bradley
publication 1770-4.1
• NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided by
different types of enclosure.
, for additional installation requirements.
Prevent 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.
• 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 when used with IP67
certified cables. (Note that environmental requirements other than IP67 may
require an additional appropriate housing.) I/O connectors are sealed DB25,
M12 (micro) or M23 styles. The mounting base ships with the module. The
1738-OB16E19M23, 1738-OB16EM12, 1738-OB16E25DS and
1738-IB16DM12 are shown below.

Mount the I/O Base
To mount the base on a wall or panel, use the screw holes provided in the
base.
The module must be mounted on a grounded metal mounting plate or other
conductive surface.
Refer to the Drilling Dimensions illustration of the base with an adapter to
help you mount the base.
Drilling Dimensions
You can only use the 1738-EP24DC expansion power unit with the 1738
ArmorPoint I/O adapters.
