2 Terms and definitions
2.1 Definitions relating to ratings, voltages, currents, frequencies, and wattages
Replace Definitions 2.1.4 and 2.1.5 with the following:
2.1.4
extra-low voltage
ELV
voltage not exceeding the maximum values of 50 V AC (RMS), 70,7 V AC (peak) or 120 V DC
(ripple-free) between conductors and between conductors and earth which is permitted to be
maintained indefinitely under normal and single-fault conditions
Note 1 to entry: Ripple-free is conventionally defined as an RMS ripple voltage of not more than 10 % of the DC
component.
Note 2 to entry: The use of ELV other than in SELV system or PELV system is not a protective measure against
electric shock, this is in line with IEC 61140:2001.
2.1.5
safety extra-low voltage
SELV
voltage for use in SELV system or PELV system between simultaneously accessible part(s)
and between any accessible part and earth, not exceeding the limits of 30 V AC (RMS), 42,4 V
AC (peak) or 60 V DC (ripple free) under normal and single-fault condition, which is provided by
an independent source (such as safety isolating transformers, motor generators, and batteries)
or when obtained from higher voltage is obtained by a safety isolating transformer or a
converter with separate windings providing equivalent insulation
Note 1 to entry: The voltage limits are based on the assumption that the safety isolating transformer is supplied
at its rated voltage. For the purpose of the output test in 24.1.1, the secondary output voltage limit shall be increased
as specified in 17.2.2.
Note 2 to entry: Transformers used in converters that have separate windings and provide equivalent insulation
are covered under IEC 61558-2-6 and IEC 61558-2-16.
Note 3 to entry: SELV limits are defined regardless of any special condition which may occur in installation. Different
requirements may be specified in the relevant electrical installation standards (e.g. IEC 60364 (all parts)) or in the
applicable local regulations.
Note 4 to entry: Ripple-free is conventionally defined as an RMS ripple voltage of not more than 10 % of the DC
component.
Note 5 to entry: SELV limits may be different in other product or system standards. In case a control is declared
exclusively for use in applications governed by a different standard, the limits set by the application standard apply
(e.g. controls to be used exclusively in household appliances according IEC 60335 set of standards or connected
to HBES/BACS systems according to IEC 63044-3 accept different SELV voltage limits).
Add the following new definition:
2.3.33
mounting surface temperature
T
s max
declared maximum temperature to which the mounting surface of the control is intended to be
exposed including any likely overshoot once a control has operated

Add the following new definition:

the occurrence of a condition which could impair compliance with this document

8.1.1
Replace the second and third paragraphs with the following:
Unless otherwise specified, accessible parts connected to SELV systems or PELV systems
where the voltage does not exceed the SELV limits of 2.1.5 are not considered to be hazardous
live parts.
For accessible parts connected to a SELV system or a PELV system where the voltage
exceeds the SELV limits of 2.1.5 or the voltage limits declared in item 87 of Table 1, the current
measured between the simultaneously accessible parts and between accessible parts and
earth shall not exceed the limits in H.8.1.10.1 under fault-free (normal) and single-fault
conditions.
