Section 2.3
General
Considerations
1762 I/O 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)

.
2.3.1 Hazardous Location Considerations
This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D or
non-hazardous locations only. The following WARNING statement applies to
use in hazardous locations.
WARNING
EXPLOSION HAZARD

Substitution of components may impair suitability for Class I,
Division 2. Touch a grounded object to discharge static potential.

Do not replace components or disconnect equipment unless power
has been switched off or the area is known to be non-hazardous.
Touch a grounded object to discharge static potential.

This product must be installed in an enclosure. Touch a grounded
object to discharge static potential.

All wiring must comply with N.E.C. article 501-4(b). Touch a
grounded object to discharge static potential.
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.
