NOTE 1 Tests specified in product standards do not need be repeated. The functioning of RCMs functionally
independent of line voltage is not affected by voltage amplitude variations. The tests of this standard apply only
to RCMs dependent on line voltage.
NOTE 2 Immunity from power frequency variations is ensured by the fact that all performances of the device
are tested at frequencies which may be subjected to variations in the range of ± 5 % of the rated frequency:
see 9.2.

A study is undertaken for possible inclusion of requirements in a future revision.

8 Requirements for construction and operation
8.1.2 Features
Replace, on page 44, the first sentence by the following:
The RCM shall be provided with a visual “Power on” indicator which shall neither be red, yellow
nor blue.
8.1.3 Clearances and creepage distances (see also Annex B)
Replace the paragraph and note before Table 2 by the following:
Clearance and creepage distances applicable to the RCM and its external components, e.g.
current transformers etc., with the exception of printed circuit boards, shall comply with the
requirements of Table 2 when the RCM is mounted as for normal use.
The above requirements shall also apply to active conductors (phases and neutral) connected
directly to the printed circuit board.
Creepage distances applicable to printed circuit boards of the RCM shall comply with the
requirements of Table 4 of IEC 60664-1, “Creepage distances to avoid failure due to tracking”,
Pollution degree 2, Material group III.
Table 4 of IEC 60664-1 includes requirements for uncoated printed circuit boards. IEC 60664-3
provides for reduced clearance and creepage distances for printed circuit boards using a
protective coating, potting or moulding. Such printed circuit boards may therefore be verified
for compliance in accordance with IEC 60664-3 instead of Table 4 of IEC 60664-1.

8.2 Protection against electric shock
Add, after the second paragraph, the following new paragraph:
The continuous current through the protective conductor shall not exceed 1 mA under normal
supply conditions.

Compliance is checked by measurement, by inspection and by the test of 9.6.
Page 57
8.6 Directional discrimination
Number the existing text as 8.6.1. Add the following new subclause 8.6.2 (former sub-
clause 5.3.10).
8.6.2 The internal impedance between line terminal and the FE terminal shall have a value
not less than 10 MΩ at 50/60 Hz. At higher frequencies the impedance may be reduced
proportionally, however to not less than 1 MΩ.
Compliance is checked by the tests under 9.9.5 e).

8.18 EMC requirements
Replace the existing title and text by the following:
8.18 Electromagnetic compatibility (Based on IEC 61543)
Standard electromagnetic environmental conditions are those conditions which occur in
installations connected to low voltage public networks or similar installations.
8.18.1 Low frequency electromagnetic phenomena
