This amendment A11 modifies the European Standard EN IEC 60335-2-76:2021; it was approved by CENELEC on 2021-09-20. CENELEC
members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this amendment the
status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC
Management Centre or to any CENELEC member.
This amendment exists in three official versions (English, French, German). A version in any other language made by translation under the

TEXT of A11 of EN IEC 60335-2-76
1 Modification to the Introduction
Add:
With this European amendment A11 the standard EN 60335-2-76:2005+A1:2006+A2:2015+A11:2008+A12:2010
is superseded.
This standard is not linked to any European legislation.
This European amendment A11 supplements or modifies the corresponding clauses of the standards below:
– EN 60335-1:2012+A11:2014+ A13:2017+A1:2019+A14:2019+A2:2019 (Part 1)
– EN IEC 60335-2-76:2021 (Part 2)
2 Modification to Clause 3 “Term and definitions”
3.8.101
standard load
Replace the definition as following:
load consisting of the non-inductive resistor R1 between 50 Ω and 500 Ω giving the most severe condition and a
non-inductive variable resistor R2 that is adjusted so as to maximize the energy per impulse or, when applicable,
the cumulated duration of peak current exceeding 20 A in the non-inductive resistor R1, whichever gives the
more unfavourable result. The non-inductive variable resistor R2 is connected in series or parallel with the non-
inductive resistor R1, whichever gives the more unfavourable result

3 Modification to Clause 6 “Classification”
6.101 Delete the clause
4 Modification to Clause 7 “Marking and instructions”
7.1 Replacement:
In the second paragraph, replace “Energy limited energizers” by “Energizers”.
7.12.1 Addition:
The installation instructions for energizers fitted with polyvinyl chloride sheathed cords shall state that the
energizer has to be located in a shelter and must not be handled when the ambient temperature is below +5 °C.
5 Modification to Clause 10 “Power input and current”
10.101 Replace “energy limited energizers” by “energizers”.
6 Modification to Clause 22 “Construction”
22.108 Replace third dashed item with:
– the energy/impulse in the non-inductive resistor R1 of the standard load shall not exceed 5 J and the peak
current in the non-inductive resistor R1 of the standard load shall not exceed 20 A for more than 200 µs
cumulated per impulse;
Delete the fourth dashed item.
22.115 Replace the first paragraph with following:
Type S security energizer group output characteristics measured in the 500 Ω resistor R shall be such that
T
• the impulse repetition rate shall not exceed 1 Hz;
• the impulse duration of the impulse shall not exceed 10 ms;
• the energy/impulse shall not exceed 5 J;
NOTE The energy/impulse is the energy measured in the impulse over the impulse duration
7 Modification to “Figures”
Delete Figure 103
8 Modification to “Annexes”
The annexes of part 1 are applicable except at follows:
Annex A
(informative)
Routine tests
A.3 Functional test
Replace the addition with following:

load connected across the output terminals.
The energizer output characteristic shall be such that
– the impulse repetition rate shall not exceed 1 Hz;
– the impulse duration of the impulse shall not exceed 10 ms;
– the energy/impulse shall not exceed 5 J;
Add the Annex ZAA:
Annex ZAA
(normative)
Time delayed electric fence energizers
The following modifications to this standard are applicable for time delayed electric fence energizers.
3 Definitions
3.ZAA.1
time delayed electric fence energizer
electric fence energizer that when a very low load impedance is detected at the output terminals, has its
maximum output impulses limited for the duration of the delay time, but permits the output impulses to rise even
above the normal maximum allowed value of 5 J after the delay time
3.ZAA.2
delay time
time the energizer waits before its maximum output energy is allowed to increase in response to a changed load
3.ZAA.3
adaptation time
time by which an energizer output has reached steady-state in response to a changed load after the delay time
has elapsed
7 Marking and instructions
7.1 Addition:
The energizer shall be marked with the substance of the words “time delayed electric fence energizer” or with
the symbol (see 7.6) and shall not be marked as being suitable for use in a security energizer group.
Compliance is checked by in
