About the End Caps/Terminators
The 1769 controllers, such as the 1769-L32E, require end caps. A 1769-ECR right end cap or
1769-ECL left end cap terminates the end of the communication bus. Use this guide to install
either end cap.

Environment and Enclosure
Compact I/O End Caps/Terminators 3
ATTENTION
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 (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 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 enclosure must have suitable flame-retardant properties to
prevent or minimize the spread of flame, complying with a flame spread rating of 5VA,
V2, V1, V0 (or equivalent) if non-metallic. 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.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, for additional installation
requirements, 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.

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.
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 an d
nonhazardous locations only. Each product is su pplied with
markings on the rating nameplate indicatin g the hazardous
location temperature code. When combining p roducts within a
system, the most adverse temperature code (lowest "T" number)
may be used to help determine the overa ll temperature code of
the system. Combinations of equipment in your system are subject
to investigation by the local Author ity Having Jurisdiction at the
time of installation.
WARNING
EXPLOSION HAZARD -
