Replace the existing text by the following:
Subclause 4.5 of IEC 60947-1 applies; moreover, for an electronically controlled electro-
magnet, 4.5.1 of IEC 60947-1 applies with the following addition.
The electronic part may form an integral part or a separate part provided it is an intrinsic
function of the device. In both cases, the device shall be tested with this electronic part
mounted as in normal use.
The characteristics of electronic control circuits are as follows:
− type of current;
− power consumption;
− rated frequency (or d.c.);
− rated control circuit voltage, U (nature: a.c./d.c.);
c
− rated control supply voltage, U (nature: a.c./d.c.);
s
− nature of external control circuit devices (contacts, sensors, optocouplers, electronic
active components, etc).
Annex E gives examples and illustrations of different circuit configurations.
NOTE A distinction is made between the control circuit voltage U , which is the controlling input signal, and the
c
control supply voltage U , which is the voltage applied to energize the power supply terminals of the control circuit
s
equipment and may be different from U due to the presence of built-in transformers, rectifiers, resistors, electronic
c
circuitry, etc.

5.8 Co-ordination with short-circuit protective devices
Replace the existing text by the following:
The co-ordination of contactors and starters is characterized by the type, ratings and
characteristics of the short-circuit protective devices (SCPD) that provide protection of the
contactor and starter against short-circuit currents. Requirements are given in 8.2.5.1 and
8.2.5.2 of this standard, and in 4.8 of IEC 60947-1.
