_____________
Add, after the Foreword, the following new text:
Introduction
Work is currently underway to modify creepage distances and clearances requirements

frequencies then 30 kHz;
• impulse and resonance ignition;
• basic, supplementary and reinforced insulation;
• insulation between circuits;
• coated or potted controlgear.
This information is expected to be incorporated into the future Edition 3 of IEC 61347-1.

3 Terms and definitions
3.23
functional earthing (ground)
Replace the existing Notes 1 and 2 of the existing definition by the following Note to entry:
Note 1 to entry: In some cases, functional earthing may be necessary to facilitate starting and/or to avoid radio
interference.
Add, after Definition 3.26, the following new definitions:

– 4 – 61347-1 Amend.2 © IEC:2012
3.27
extra-low voltage
ELV
voltage which does not exceed 50 V a.c. or 120 V ripple free d.c. between conductors, or
between any conductor and earth (voltage band 1 of IEC 60449:1973)
Note 1 to entry: “Ripple free” is conventionally defined for sinusoidal ripple voltage as a ripple content of not more
than 10 % r.m.s. The maximum peak value does not exceed 140 V for a nominal 120 V ripple-free d.c. system.
3.28
safety extra low voltage
SELV
ELV in a circuit which is isolated from the mains supply by insulation not less than that
between the primary and secondary circuits of a safety isolating transformer according to
IEC 61558-2-6
Note 1 to entry: Maximum voltage lower than 50 V a.c. r.m.s. or 120 V ripple free d.c. may be specified in
particular requirements, especially when direct contact with current-carrying parts is allowed.
Note 2 to entry: The voltage limit should not be exceeded at any load between full loads and no-load when the
source is a safety isolation transformer.
Note 3 to entry: “Ripple free” is conventionally an r.m.s. ripple voltage not more than 10 % of the d.c. component:
the maximum peak value does not exceed 140 V for a nominal 120 V ripple free d.c. system and 70 V for a nominal
60 V ripple free system.
