_____________
1 Scope
Replace the first paragraph with the following new text:
This part of IEC 61347 specifies general and safety requirements for lamp controlgear for use
on d.c. supplies up to 1 000 V and/or a.c. supplies up to 1 000 V at 50 Hz or 60 Hz.
3 Terms and definitions
Add, at the end of Clause 3, the following new definition:
3.49
surge protective device
SPD
device that is intended to limit transient overvoltages and divert surge currents and which
contains at least one nonlinear component
Note 1 to entry: This note applies to the French language only.

7.1 Items to be marked
Replace, in item f), the third paragraph with the following new text:
Controlgear with an integrated SPD requiring connection to earth shall be marked with the
protective earth symbol according to IEC 60417-5019: 2006-08.
Replace existing item s) with the following new item s):
s) SELV circuits in lamp controlgear shall be identified by the following symbol which shall be
readable with normal or corrected vision:
SELV
Replace under item u), the second bulleted list item with the following new list item:
• any output terminal and earth (if applicable – particularly, SELV-circuits are excluded)
Replace Table 2 with the following new Table 2:
Table 2 – Working voltage and U steps
out
Working voltage < 50 V a.c. or < 500 V a.c. or d.c. ≥ 500 V a.c. or d.c.
≤ 120 V d.c.
U in steps of 1 V 10 V 50 V
out
Add, after item w), the following new item x):
x) Indication: “Integrated SPD” for CLASS I application if an overvoltage protective device is
integrated in the controlgear.
Replace the existing Clause 8 with the following new Clause 8:
8 Terminals
8.1 Integral terminals
Integral terminals shall comply with the following clauses of IEC 60598-1:
• Clause 14 for screw terminals;
• Clause 15 for screwless terminals.
Compliance is checked by inspection and the relevant tests.
8.2 Terminals other than integral terminals
Terminals, other than integral terminals, shall comply with the requirements of the relevant
IEC standards, if any.
Terminals which comply with the requirements of the relevant IEC standard and marked with
individual ratings shall suit the conditions which may occur in use.
Aspects of use not covered by the respective standard shall require them to satisfy the
additional relevant requirements of this standard.

– 4 – IEC 61347-1:2015/AMD1:2017
© IEC 2017
Terminals complying with the requirements of their own standard and used in accordance with
their intended use, shall only meet the requirements of this standard where there are no
requirements in the "terminals" standard.
Compliance is checked by inspection and the relevant tests.
NOTE Example terminal standards are IEC 60947-7-4, IEC 60838-2-2 and IEC 60998 (all parts).
10.4
Replace the fifth paragraph with the following new text:
Accessible conductive parts separated by double or reinforced insulation, for example live
parts and the body or primary and secondary circuits, may be bridged (conductive bridged) by
resistors or Y2 capacitors provided they consist of at least two separate components of the
same rated value (resistance or capacitance) in series and each component is rated for the
total working voltage and whose impedance is unlikely to change significantly during the
individual lifetime of the controlgear. In addition, accessible conductive parts separated by
double or reinforced insulation from live parts, as above, may be bridged by a single Y1
capacitor.
11 Moisture resistance and insulation
Add, at the end of Clause 11, the following new text:
The over voltage protective device (SPD) is disconnected if it complies with IEC 61643-11
when conducting the insulation and electric strength test.
14.5
Add, at the end of Subclause 14.5, the following new text:
Short circuit across or, if applicable, interruption of components for SPDs (e.g. MOV, VDR or
spare gaps components). Only one component at a time shall be short circuited (or
interrupted).
14.7
Replace the first paragraph with the following new text:
Connect the controlgear under test to a high-power a.c. and in turn to a d.c. (if claimed so)
+10
supply capable of passing a fault current of 160 A % r.m.s., as shown in Figure 2.
16.1 General
Add between the eighth paragraph and NOTE 1 the following new text:
The insulation properties of printed circuit board over a metallic substrate (metal core printed
circuit board – MCPCB) are only to be considered as a single level of insulation (basic or
supplementary).
© IEC 2017
16.2.1 General
Replace the second paragraph with the following new text:
For the dimensioning of the creepage distances the r.m.s. values of the working voltage
(Table 7) shall be taken into account. In case of insulation between circuits and accessible
parts, the requirements in 15.4 shall be taken into consideration to find the working voltage.
Replace Figure 4 with the following new Figure 4:
