Environment and Enclosure
Preventing Electrostatic Discharge
ATTENTION
This equipment is intended for use in a Pollution Degree 2 industrial
environment, 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 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 250 and IEC 60529, as applicable, for explanations of
the degrees of protection provided by different types of enclosure.
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.

Publication 1762-IN012C-EN-P - June 2013
Overview
The 1762 input module is suitable for use in an industrial environment when installed in
accordance with these instructions. Specifically, this equipment is intended for use in clean, dry
environments (Pollution degree 2(1)) and to circuits not exceeding Over Voltage Category II(2)
(IEC 60664-1)(3).
Install your module using these installation instructions.
1762 Input Module
(1) Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation shall be expected.
(2) Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are
controlled and do not exceed the impulse voltage capability of the product’s insulation.
(3) Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.
ATTENTION
Do not remove the protective debris strip until after the module and all other
equipment in the panel near the module are mounted and wiring is complete.
Once wiring is complete, remove protective debris strip. Failure to remove strip
before operating can cause overheating.
ATTENTION
Electrostatic discharge can damage semiconductor devices inside the module.
Do not touch the connector pins or other sensitive areas.

Mount the Module
General Considerations
Most applications require installation in an industrial enclosure to reduce the effects of electrical
interference and environmental exposure. Locate your controller as far as possible from power
lines, load lines, and other sources of electrical noise such as hard-contact switches, relays, and
AC motor drives. For more information on proper grounding guidelines, see the Industrial
Automation Wiring and Grounding Guidelines, publication 1770-4.1.
Mounting Dimensions
ATTENTION
This product is intended to be mounted to a well-grounded mounting surface
such as a metal panel. Additional grounding connections from the power
supply's mounting tabs or DIN rail (if used) are not required unless the mounting
surface cannot be grounded. Refer to Industrial Automation Wiring and
Grounding Guidelines, Allen-Bradley publication 1770-4.1, for additional
information.

Module Spacing
Maintain spacing from objects such as enclosure walls, wireways and adjacent equipment. Allow
50.8 mm (2 in.) of space on all sides for adequate ventilation, as shown:
DIN Rail Mounting
The module can be mounted using the following DIN rails: 35 x 7.5 mm (EN 50 022 - 35 x 7.5)
or 35 x 15 mm (EN 50 022 - 35 x 15).
Before mounting the module on a DIN rail, close the DIN rail latch. Press the DIN rail
mounting area of the module against the DIN rail. The latch will momentarily open and lock
into place.
Use DIN rail end anchors (Allen-Bradley part number 1492-EA35 or 1492-EAH35) for
vibration or shock environments.
TIP
For environments with greater vibration and shock concerns, use the panel
mounting method described below, instead of DIN rail mounting.

Panel Mounting
Use the dimensional template shown below to mount the module. The preferred mounting
method is to use two M4 (#8) panhead screws per module. M3.5 (#6) panhead screws may also
be used, but a washer may be needed to ensure a good mechanical contact. Mounting screws are
required on every module.
System Assembly
The expansion I/O module is attached to the controller or another I/O module by means of a
flat ribbon cable after mounting as shown below.
TIP
Use the pull loop on the connector to disconnect modules. Do not pull on the
ribbon cable.
