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

and to circuits not exceeding Over Voltage Category

(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.

Attention

EXPLOSION HAZARD

 Substitution of components may impair suitability for Class I,

Division 2.

 Do not replace components or disconnect equipment unless

power has been switched off or the area is known to be non-

hazardous.

 Do not connect or disconnect components unless power has

been switched off or the area is known to be non-hazardous.

 This product must be installed in an enclosure.

 All wiring must comply with N.E.C. article 501-4(b).

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.

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.

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

designations.
