Installation
1762 I/O is suitable for use in an industrial environment whe n installed in
accord an ce with the se in struction s . Sp e ci fic ally, this equipm en t is in tended for
use in clean, dry environments ( Po llution degre e 2
exceeding Over Vo ltage Cat egory II

(IEC 60664-1).
Prevent Electrostatic Discharge

!
Remove Power
!
ATTENTION:
circuits or semiconductors if you touch bus connector pins.
Follow these guidelines when you handle the module:
Touch a grounded objec t to discharge static potential.
•
Wear an approved wris t-strap grounding de vice.
•
Do not touch the bus connector or connector pins.
•
Do not touch circuit components inside the module.
•
If av ailabl e, use a static-safe work sta tion.
•
When not in use, keep the module in its static-shield box.
•
ATTENTION:
this module. When you remove or install a mo dule with power
applied, an electrical arc may occur. An electrical arc can cause
personal injury or property damage by:
sending an erroneous signal to your system’s field devices ,
•
causing unint ended machine motion
causing an explosion in a hazardous environment
•
causing permanent damage to the module’s circuitry
•
Electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may cre ate
electri cal resistan c e .
Electrostatic discharge can damage integrated
Remove po wer before removing or inst alling

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.

Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC)
designations.

Mounting
ATTENTION:

!
wiring is complete. Once wiring is complete and the module is free
of debris, carefully remove protective debris strip. Failure to
remove strip before operating can cause overheating.
Minimum Spacing
Main ta in s p ac ing from
enclosure walls,
wireways, adjacent
equipment, etc. Allow
50.8 mm (2 in.) of space
on all side s for ad eq u at e
ventilation, as sho wn:
Note:
1762 expansion I/O ma y be mounted horizontally onl y.
A TT ENTION:
be sure that all debris (metal chips, wire strands, etc.) is kept from
!
falling into the module. Debris that falls into the module could
cause damage when power is applied to the module.
Do not remove protective debris strip until after
