This document provides guidelines to ensure that graphical symbols for use on equipment in IEC product publications are consistent with the requirements of horizontal publication IEC 60417, and ISO 7000. This document is intended to be used by any committees to develop graphical symbols for use on equipment for inclusion in their product publications.

This document is based on and develops IEC Guide 108:2019, Clause 8.

For the creation of new graphical symbols for use on equipment, IEC 80416-1 and ISO 80416‑2 are used. For the application of standardized graphical symbols for use on equipment, IEC 80416-3 and ISO 80416-4 are used.

This horizontal publication is primarily intended for use by committees in the preparation of publications in accordance with the principles laid down in IEC Guide 108.

One of the responsibilities of a committee is, wherever applicable, to make use of horizontal publications in the preparation of its publications. The contents of this horizontal publication will not apply unless specifically referred to or included in the relevant publications.

The purpose of this guide is to establish, in a general way, suitable procedures and tolerances for the installation of Pelton vertical turbines. This guide presents a typical assembly and whenever the word “turbine” is used in this part, it refers to a vertical Pelton turbine. There are many possible ways to assemble a unit. The size of the machine, the design of the machine, the layout of the powerhouse or the delivery schedule of the components are some of the elements that could result in additional steps, or the elimination of some steps and/or assembly sequences.

It is understood that a publication of this type will be binding only if, and to the extent that, both contracting parties have agreed upon it.

The guide excludes matters of purely commercial interest, except those inextricably bound up with the conduct of installation.

The tolerances in this guide have been established upon Best Practices and experience, although it is recognized that other standards are specifying different tolerances

Wherever the guide specifies that documents, drawings or information shall be supplied by a manufacturer (or by manufacturers), each individual manufacturer shall be required to furnish the appropriate information for their own supply only.

IEC 62271-207 applies to:

gas-insulated switchgear (GIS) assemblies

for alternating current of rated voltages above 52 kV complying with IEC 62271-203

for direct current of rated voltages including and above 100 kV

for indoor and outdoor installations, including their supporting structures.

metal-enclosed switchgear and controlgear assemblies for rated voltages above 1 kV and up to and including 52 kV complying with IEC 62271-200 for metal-enclosed and IEC 62271-201 for solid-insulation enclosed, ground or floor mounted, intended to be used under seismic conditions.

The seismic qualification of the switchgear assemblies takes into account testing of typical switchgear assemblies combined with methods of analysis. Mutual interaction between directly mounted auxiliary and control equipment and switchgear assemblies is considered.

Seismic qualification philosophy includes selection of seismic qualification level (Clause 4), methodologies for qualification by testing (Clause 5) and by combined testing and analysis (Clause 6), acceptance criteria (Clause 7) and seismic qualification documentation (Clause 8).

The seismic qualification of switchgear assemblies by the manufacturer is only performed upon request of the user.

This part of IEC 63171 covers shielded free and fixed circular connectors with 4 ways up to 7 ways for power and data transmission and specifies the common dimensions, mechanical, electrical and transmission characteristics and environmental requirements as well as test specifications respectively.

The connectors described in this document are either equipped with a M12 screw-locking mechanism (styles with M12 in the name) or a quick-locking push-pull mechanism with a size derived from that (styles with P12 in the name) or both mechanisms combined (styles with C12 in the name). For the sake of simplicity, the connectors’ size is denoted as “size 12” in this document.

This document provides multiple mating interfaces each of which is associated with a coding preventing the mating of incompatible male and female connectors. These codings are referred to as “Type x” where ‘x’ is represented by a Roman number.

For all codings, two ways and the additional shield pin intended to be connected to the cable sheath support differential data transmission with frequencies up to 600 MHz by meeting the requirements of Category B as defined in IEC 63171.

NOTE 1 Connecting the shield pin to the cable sheath is also required for data transmission with frequencies up to 20 MHz (IEC 63171, Category A).

NOTE 2 The connectors are intended to be used for single-pair Ethernet (SPE) according to the following IEEE Standards: 10BASE-T1 (IEEE 802.3cg), 100BASE-T1 (IEEE 802.3bw), 1000BASE-T1 (IEEE 802.3bp).

NOTE 3 Power over Data line (PoDL) power supply according to IEEE 802.3bu can be optionally used for the two ways intended for data transmission, even in addition to the power supply provided through the dedicated power ways.

The individual codings differ by their power transmission capabilities and intents. The additional ways provide for DC power transmission with up to 63 V/16 A and 600 V/16 A or AC power transmission with rated voltage and rated current up to 600 V/16 A (single-phase) or 480 V/8 A (three-phase). See Table 11 and Table 12 for the voltage and current ratings, and Table 5 for the pin assignments for the individual codings.

Some codings feature a PE pin for safety purposes.

NOTE 4  The PE needs to be connected to all accessible metal parts.

This part of IEC 60364 provides requirements for:

protection of live conductors, PEN conductors, PEM conductors, and PEL conductors against the harmful effect caused by overcurrent.

coordination of measures for protection against overcurrent

NOTE 1 The requirements of this standard do not take account of external influences.

NOTE 2 Protection of conductors according to this standard does not necessarily protect the equipment connected to the conductors.

NOTE 3 Flexible cables connecting equipment by plugs and socket-outlet to fixed installations are not part of the scope of this standard and for this reason are not necessarily protected against the harmful effect caused by overcurrent.

NOTE 4 Disconnection does not mean isolation in this standard.
