all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.

4 Specific requirements for power sources with energy harvesting
4.1 General
IEC 62952-1:2016, Figure 1 shows the possible various types of power modules that can be
used as a power source within a WCD system level and architecture description.
Power modules are elements for WCD to provide power or supplementary power to the WCD.
4.2 GEHAM and energy harvester
Power Module Type C shall consist of GEHAM and energy harvester.
Annex A provides implementation options how the power source can be designed with the
energy harvester and GEHAM as separated or integrated elements.
GEHAM accommodates the following functions.
• GEHAM shall provide the necessary mechanical interface between the energy harvester
and WCD.
• GEHAM should include any power conditioning such as rectification and voltage control to
ensure that the GEHAM output conforms to this standard.
• GEHAM should provide the power management necessary to ensure that power is stored
in a suitable energy storage capacitor or secondary battery.
• GEHAM shall supply energy at a suitable voltage to WCD.
• GEHAM may include batteries (primary or secondary) as backup in case power from the
energy harvester is insufficient.
• GEHAM should ensure that power is used preferentially from the energy harvester before
using power from the backup batteries included in the GEHAM.
• When the energy harvester supplies voltage above the nominal voltage then the GEHAM
can provide intermediate energy storage capacity that is sufficient to power the device
during high-power cycles.
4.3 Mechanical requirements
4.3.1 Connector
Connection shall be downward compatible with respect to capability of connector options (2, 3,
4, 5-pin options).
Example
If a 2-pin male connector is plugged into a 4-pin female cable end between the energy harvester and GEHAM, the
connection shall work without the additional capability/information provided on the pins not connected.
In cases where a connector is used, IEC 61076-2-101 M12 A-Coded connectors shall be used.
Male connectors shall be on both devices, and cable ends shall be female on both ends.
4.3.2 Flying lead
This document shall accommodate flying lead on either end, connecting to a terminal strip or
similar on either or both devices.
If a flying lead is used to connect to the GEHAM/WCD, then the terminals shall be clearly
labeled with text, for example with + and –.

– 10 – IEC 62952-3:2017 © IEC 2017
4.3.3 Cable specification
Cable colors shall be compliant with IEC 60304. In case of a flying lead connection, the cable
shall be between 5 mm and 10 mm in nominal outside diameter.
Wire shall be between 0,3 mm and 1,3 mm in nominal diameter depending on the conductors
in the cable.
4.3.4 Enclosure shape
Enclosed type GEHAMs provide additional mechanical protection through having to fit inside
the WCD similar to Type A and Type B defined in IEC 62952-1.
4.4 Electrical characteristics
4.4.1 General
GEHAM is an interface device between the energy harvester and the WCD. To ensure the
interchangeability, input and output rating of GEHAM shall be complied.
4.4.2 Input rating of GEHAM
Maximum input power (Pi) shall be restricted to the capabilities of the used cable and
connectors according to the regulations for electrical safety.
The maximum voltage (Vi) of the GEHAM shall be 30 V DC.
4.4.3 Output rating of GEHAM
The output voltage of GEHAM shall be DC, non-regulated and the ripple shall not exceed the
stated maximum output voltage.
The maximum output voltage provided may be 5 V DC (for a nominal single battery, 3,6 V
capacity) or 10 V DC (for a nominal dual battery, 7,2 V capacity).
The GEHAM shall be clearly labeled to identify whether it is 3,6 V or 7,2 V nominal.
4.4.4 Protections
It is recommended that WCD have over voltage input protection of >12 V DC for preventing
inadvertent connection of GEHAM.
It is recommended that GEHAM have over voltage input protection of > 30 V DC for
preventing inadvertent connection of harvester and disturbance as for example a surge.
This document does not override or replace the requirements of any hazardous area
certification.
4.5 Communication interface
Pin 2 (see Clause B.3) is available for digital communication interface to provide static and
dynamic information from an energy harvester.
5 Profile for power modules with energy harvesting
The general requirements for the power modules are specified in IEC 62952-1. Table 3
specifies general power module profile selection.

Table 4 specifies the Power Module Type C profile selection within IEC 62952-3.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l’IEC). L’IEC a pour
objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines
de l'électricité et de l'électronique. A cet effet, l’IEC – entre autres activités – publie des Normes internationales,
des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au public (PAS) et des
Guides (ci-après dénommés "Publication(s) de l’IEC"). Leur élaboration est confiée à des comités d'études, aux
travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les organisations
internationales, gouvernementales et non gouvernementales, en liaison avec l’IEC, participent également aux
travaux. L’IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO), selon des
conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l’IEC concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l’IEC
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de l’IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l’IEC. Tous les efforts raisonnables sont entrepris afin que l’IEC
s'assure de l'exactitude du contenu technique de ses publications; l’IEC ne peut pas être tenue responsable de
l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de l’IEC s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l’IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l’IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) L’IEC elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de l’IEC. L’IEC n'est responsable d'aucun des services effectués par les organismes de certification
indépendants.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à l’IEC, à ses administrateurs, employés, auxiliaires ou mandataires,
y compris ses experts particuliers et les membres de ses comités d'études et des Comités nationaux de l’IEC,
pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre dommage de quelque
nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les f
