Adjustable speed electrical power drive systems - Part 5-3: Safety requirements - Functional, electrical and environmental requirements for encoders (IEC 61800-5-3:2021)
EN IEC 61800-5-3:2023

This part of IEC 61800, which is a product standard, specifies requirements and makes
recommendations for the design and development, integration and validation of safety-related
encoder (Encoder(SR)) in terms of their functional safety considerations, electrical safety and
environmental conditions. It applies to Encoder(SR), being sensors as part of a PDS(SR).
NOTE 1 The term "integration" refers to the Encoder(SR) itself, not to its incorporation into the safety-related
application.
This document can also be referred to and used for Encoder(SR) in any other safety-related
application, for example safety-related position monitoring.
NOTE 2 This document specifies only complementary functional safety, electrical safety and environmental condition
requirements that are not clearly provided by other parts of the IEC 61800 series.
This document is applicable where functional safety of an encoder is claimed and the
Encoder(SR) is operating mainly in the high demand or continuous mode.
NOTE 3 While low demand mode operation is possible for an Encoder(SR), this document concentrates on high
demand and continuous mode. Safety sub-functions implemented for high demand or continuous mode can also be
used in low demand mode. Requirements for low demand mode are given in IEC 61508 (all parts) [2]. Some guidance
for the estimation of average probability of dangerous failure on demand (PFDavg) value is provided in
IEC 61800-5-2:2016, Annex F.
The requirements of IEC 61800-5-2:2016 for PDS(SR) apply to Encoder(SR) as applicable. This
document includes additional or different requirements for Encoder(SR). It sets out safetyrelated
considerations of Encoder(SR) in terms of the framework of IEC 61508 (all parts), and
introduces requirements for Encoder(SR) as subsystems of a safety-related system. It is
intended to facilitate the realisation of the electrical/electronic/programmable electronic
(E/E/PE) and mechanical parts of an Encoder(SR) in relation to the safety performance of safety
sub-function(s) of an Encoder(SR).
Manufacturers and suppliers of Encoder(SR) will, by using the normative requirements of this
document, indicate to users (system integrator, original equipment manufacturer) the safety
performance of the Encoder(SR). This will facilitate the incorporation of Encoder(SR) into
safety-related control systems using the principles of IEC 61508 (all parts), and possibly its
specific sector implementations (for example IEC 61511 (all parts) [3], IEC 61513 [4],
IEC 62061 [5] or ISO 13849-1 and ISO 13849-2 (see Clause 2).
By applying the requirements from this document, the corresponding requirements of
IEC 61508 (all parts) that are necessary for an Encoder(SR) are fulfilled.
This document does not specify requirements for:
• the functional properties of an Encoder(SR) without any safety relevance;
• the hazard and risk analysis of a particular application;
• the identification of safety sub-functions for that application;
• the initial allocation of SILs to those safety sub-functions;
• the driven equipment except for interface arrangements;
• secondary hazards (for example from failure in a production or manufacturing process);
• the Encoder(SR) manufacturing process;
• the validity of signals and commands to the Encoder(SR); and
• security aspects (e.g. cyber security or Encoder(SR) security of access).
NOTE 4 The functional safety requirements of an Encoder(SR) are dependent on the application, and can be
considered as a part of the overall risk assessment of the installation. Where the supplier of the Encoder(SR) is not
responsible for the driven equipment, the installation designer is responsible for the risk assessment, and for
specifying the functional and safety integrity requirements of the Encoder(SR).
This document applies to Encoder(SR) implementing safety sub-functions with a SIL not greater
than SIL 3.
This document provides additional information for Encoder(SR) claiming

High-voltage switchgear and controlgear - Part 104: Alternating current switches for rated voltages higher than 52 kV

IEC 62271-104:2015 is applicable to three-pole alternating current switches for rated voltages higher than 52 kV, having making and breaking current ratings, for indoor and outdoor installations, and for rated frequencies up to and including 60 Hz. This standard is also applicable to the operating devices of these switches and to their auxiliary equipment. This second edition replaces and cancels the first edition published in 2009 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- the title was changed such that the voltage range now is >52 kV instead of ≥52 kV;
- the references have been updated;
- the comments in 17A/1063/RVC have been addressed.
This publication is to be read in conjunction with IEC 62271-1:2007, IEC 62271-100:2008, IEC 62271-102:2001  and IEC 62271-110:2012.

Railway applications - Fixed installations - Particular requirements for alternating current switchgear - Part 1: Circuit-breakers with nominal voltage above 1 kV
EN 50152-1:2012/A1:2013

This EN 50152-1 is applicable to single-pole and two-pole alternating current (a.c.) circuit-breakers which are:
- for indoor or outdoor fixed installations in tractions systems, and
- operated with an a.c. line voltage and frequency as specified in EN 50163.
NOTE 1 EN 50163 specifies the a.c. traction systems 15 kV 16,7 Hz and 25 kV 50 Hz. NOTE 2 As rails of a.c. traction systems are connected to earth and included in the return current path all phase to earth voltages will be within the tolerances as specified in EN 50163. Nevertheless phase to phase voltages are sometimes higher e.g. in autotransformer systems. This European Standard is also applicable to the operating devices of circuit-breakers and to their auxiliary   equipment. This European Standard does not address circuit-breakers with dependent manual operating mechanism. NOTE 3 It is impossible to specify a rated short-circuit making current for these circuit-breakers and it is likely that such dependent manual operation is not meeting safety considerations.
