however, outdoor types can be installed in situations that are accessible to ordinary persons
• intended for use in energy distribution in public power grids;
• indoor use: assemblies for installation inside of electric power substations;
• outdoor use: assemblies containing an enclosure suitable for open air installation.
The object of this document is to state the definitions and to specify the service conditions,
construction requirements, technical characteristics and tests for PENDAs. Tests at higher
performance level can be applicable with some network parameters.
PENDAs can also include control and or signalling devices associated with the distribution of
electrical energy.

This document does not apply to individual devices and self-contained components, such as
motor starters, fuse switches, electronic equipment, etc. which comply with the relevant product
standards.
If the substation is owned or operated by a public distribution system operator (DSO), PENDA’s
which are used as LV distribution panels in transformer substations are within the scope of this
document,
This document does not apply to specific types of assemblies covered by other parts of
IEC 61439 series.
NOTE 2 If a PENDA is equipped with additional equipment (for example meters), in such a way that the main
function is changed considerably, then other standards can also apply as agreed between user and manufacturer
(see 8.5 of IEC 61439-1:2020).
NOTE 3 Where local regulations and practices permit, a PENDA according to this document can be used in other
than public networks.

This part of IEC 60947 series specifies requirements for control units, which control a switching device in response to the PTC thermistors incorporated in rotating electrical machines and the industrial application.
It specifies requirements for that type of system comprising a positive temperature coefficient (PTC) thermistor having particular characteristics, and its associated control unit.
This document includes:
- the characteristics, construction, performance and tests of the control unit; and
- its association with a PTC thermistor designated "Mark A".
This document does not cover:
- the incorporation of thermal protections into rotating machines and their maximum winding temperature. See IEC 60034-11;
- use of the product within explosive atmospheres (see IEC 60079 series);
- software and firmware requirements;
NOTE 1 Guidance on embedded software is given in IEC TR 63201.
- cyber security aspects (see IEC TS 63208).
NOTE 2 It is not possible to specify all the requirements for the operating characteristics of a control unit, as they are dependent on some aspects of the PTC thermistors. Some aspects of the requirements of the thermal protector system can only be specified when account is taken of the characteristics of the rotating machine to be protected and the method of installation of the PTC thermistor within the machine.

IEC 62026-3:2014 specifies an interface system between single or multiple controllers, and control circuit devices or switching elements. The interface system uses two conductor pairs within one cable - one of these pairs provides a differential communication medium and the other pair provides power to the devices. This part establishes requirements for the interoperability of components with such interfaces. This third edition of IEC 62026-3 cancels and replaces the second edition published in 2008. This third edition constitutes a technical revision. The main changes with respect to the previous edition are the followings: - specification of group 4 messages (5.1.2); - clarifications on messaging protocol (5.2); - addition of I/O multicast poll messages (5.5.2 and 5.5.8); - clarifications on slave behaviour (5.5.4 and 5.5.9); - clarifications on physical layer (transceiver) in 5.7; - miscellaneous corrections/clarifications on cable (8.2); - clarifications on EMC testing (9.2.10) and logical testing (9.3).

IEC 60947-9-1:2019 covers low-voltage arc quenching devices, hereinafter referred to as AQDs, which are intended to eliminate arc-faults in low-voltage assemblies (typically low-voltage switchgear and controlgear assemblies in accordance with the IEC 61439 series), by creating a lower impedance current path, to cause the arcing current to transfer to the new current path. This new current path is maintained until a short-circuit protection device (SCPD) interrupts the short-circuit current. AQDs are installed in low-voltage assemblies, connected to the main circuit, preferably as close as possible to all primary power sources. Their rated voltage does not exceed 1 000 V AC or 1 500 V DC.

EN-IEC 60947-5-2 applies to inductive and capacitive proximity switches that sense the presence of metallic and/or non-metallic objects, ultrasonic proximity switches that sense the presence of sound reflecting objects, photoelectric proximity switches that sense the presence of objects and non-mechanical magnetic proximity switches that sense the presence of objects with a magnetic field. Products covered by the scope of this document are not subjected to defined behaviours under fault conditions. Proximity switches with defined behaviour are covered by IEC 60947-5-3 and have to fulfil additional requirements. These proximity switches are self-contained, have semiconductor switching element(s) and are intended to be connected to circuits, the rated voltage of which does not exceed 250 V 50 Hz/60 Hz AC RMS or 300 V DC. Examples of typical applications for in-scope products: - factory automation and machinery industry; - logistic and packaging industry; - conveyor belts, lifts; - process industry; - power plants. Special applications (e.g. corrosive atmosphere) can cause additional requirements. This document is not intended to cover proximity switches with analogue outputs. The object of this document is to state for proximity switches: - definitions; - classification; - characteristics; - product information; - normal service, mounting and transport conditions; - constructional and performance requirements; - tests to verify rated characteristics. Products covered by the scope of this document are expected to be selected, installed, and maintained by skilled personnel only.
