This document applies to plugs，fixed or portable socket-outlets，and appliance inlets,hereinafter referred to as accessories, with a rated operating voltage not exceeding 1 0o0 v Dcor 1 000 V AC with a frequency not exceeding 500 Hz and a rated current not exceeding 125 A,primarily intended for industrial use, either indoors or outdoors.
These accessories are intended to be installed by instructed persons or skilled persons only.
NOTE 1 All references for accessories with a rated current of more than 125 A in IEC 60309-1 are not applicableto this document.
This document applies to accessories with pins and contact-tubes of standardizedconfigurations.
This document applies to accessories, for use when the ambient temperature is normally withinthe range -25 °c to 40°C.
The use of these accessories on building sites and for agricultural, commercial and domesticapplications is not precluded.
This document applies to accessories with screwless-type terminals or insulation piercingterminals,with a rated current up to and including 32 A for series l and 30 A for series ll.
Socket-outlets or appliance inlets incorporated in or fixed to electrical equipment are within thescope of this document. This document also applies to accessories intended to be used inextra-low voltage installations.
NOTE2 This document does not apply to accessories primarily intended for domestic and similar general purposes.In locations where special conditions prevail, for example on board ship or where explosionsare liable to occur,additional requirements can be necessary.

7 Marking
Clause 7 of lEC 60309-1:2021 applies except as follows:
7.1 Replace the sentence before the compliance statement at the end of the subclause bythe following paragraphs:
The symbol indicating the position of the earthing contact or of the minor key or keyway shallbe placed before or above the value for the rated operating voltage and separated from it by aline.
These markings shall be placed after the marking for rated current, separated from it by a dashif an oblique line separates the symbol indicating the position of the earthing contact or of theminor key or keyway from the value for the rated operating voltage.
lf a symbol for nature of supply is used, it shall be placed after or below the marking for ratedoperating voltage.
For three-phase accessories it is not necessary to mark the voltage phase to neutral, if any.The marking for rated current(s)，position of the earthing contact or the minor key，keyway,rated operating voltage(s) and nature of supply accordingly may be as follows.IEC 60309-2 pdf download.
