Standards Development

Scope

Replace the full text below Figure 1 of Clause 1 with:

“Components of the above-named equipment and within the scope of this document are, for example:

— (auxiliary) stand-alone power supplies;

— peripherals such as digital and analogue I/O;

— remote-I/O;

— industrial network equipment, embedded or stand-alone (e.g. switches, routers, wireless base station).

Control equipment and their associated peripherals are intended to be used in an industrial environment and are provided as either open or enclosed equipment.

NOTE Control equipment intended also for use in other environments or for other purposes (example: for use in building installations to control light or other electrical installations, or for use on cars, trains or ships) can have additional conformity requirements defined by the safety standard(s) for these applications. These requirements can involve for example: insulation, spacings and power restrictions.

Equipment covered in this document is intended for use in overvoltage category II (IEC 60664‑1) in low-voltage installations, where the rated equipment supply voltage does not exceed AC 1 000 V r.m.s. (50/60 Hz), or DC 1 000 V. If control equipment or their associated peripherals are applied in overvoltage category III installations, then additional analysis will be required to determine the suitability of the equipment for those applications.

The object of this document is to define clear, complete, and exhaustive technical requirements to products falling in its scope.

Safety requirements for control equipment and their associated peripherals are specified in IEC 61010‑2‑201.”
