Note 1 to entry: The protection circuitry is usually a combination of hardware and software.
Note 2 to entry: This protection is typically achieved through an algorithm based on the I t of the current to the
motor.
3.46
electronic power output short-circuit protection circuitry
circuitry integral to PDS/CDM/BDM that acts to significantly reduce current flow to the power
output upon sensing a short-circuit condition
Note 1 to entry: The protection circuitry is usually a combination of hardware and software.
3.47
thermal memory
ability of an overload protective system to approximate the heating and cooling of a protected
motor during operation
3.48
thermal memory retention
ability to retain a representation of the thermal state of a motor prior to shutdown or loss of
power
Note 1 to entry: Typically, this information will be used by the overload protective system to approximate the
thermal state of the motor upon restart.
Note 2 to entry: This may include an ongoing reduction of the thermal representation to reflect cooling of the motor
during shutdown or loss of power.
3.49
trip
controlled rapid reduction or elimination of the transfer of energy to any device or process
initiated by a detected fault or abnormal operating condition
4.3.6.1.4 Supply earthing systems
Add, at the end of the first bullet point, the following new sentence:
A corner-earthed system is a TN system with one phase earthed.
Add, at the end of the second bullet point, the following new sentence:
A corner-earthed system is a TT system with one phase earthed.
Add, after the third bullet point, the following new paragraph:
In a PDS designed for operation on a corner-earthed system, the
• insulation between phases of the mains supply, including the earthed phase, may be
designed for functional insulation according to clause 4.3.6.3, and
• circuits within the PDS/CDM/BDM directly connected to any phase of a corner-earthed
system shall be separated from earthed parts by at least basic insulation.
Table 7 — Insulation voltage for low voltage circuits
Replace, at the bottom of Table 7, Note 1 by the following new paragraph;
Interpolation of system voltage is not permitted when determing the impulse voltage for mains supply. Interpolation
of system voltage is permitted when determining the temporary overvoltage for mains supply.
Replace, at the bottom of Table 7, the indication "NOTE 2" by "NOTE".

Add, at the bottom of Table 7, after the note, the following indication:
SOURCE: IEC 62477-1:2012, Table 9
4.3.6.4.1 Determination
Replace, in the fourth paragraph, the first bullet point by the following new bullet point:
• for low-voltage PDS, the value corresponding to the next higher impulse voltage, or 1,6
times the temporary overvoltage, or 1,6 times the working voltage shall be used (see
IEC 60664-1:2007, 5.1.6 and IEC 62477-1: 2012, 4.4.7.4.1);
4.3.6.8.3.1 General
Add, after the first paragraph, the following new paragraph:
4.3.6.8.3 also applies to components providing insulation. See 4.3.6.8.1 for the use of
component standards.
4.3.9 Output short-circuit requirements
Add, after the first paragraph, the following new paragraphs:
The short-circuit evaluation of each power output of the CDM/BDM shall include short-circuits
of both
• phase to phase, and
• each phase to earth.
If the CDM/BDM provides galvanic isolation between all power ports and a power output, then
evaluation of phase to earth short-circuits for that specific power output, and any additional
power outputs with galvanic isolation, is not necessary.
Compliance with the requirement of IEC 60364-4-41:2005/AMD1:— , Clause 411 and Annex D
is shown by
• testing according to 5.2.3.6.5, or
• supplementary protective equipotential bonding in accordance with IEC 60364-4-
41:2005/AMD1:—, 415.2.
The electronic power short-circuit protection circuitry relied on to demonstrate compliance
with the short-circuit test in 5.2.3.6.3 shall also comply with the requirement of 5.2.9.
NOTE IEC 60364-4-41:2005/AMD1:—, 411.3.2, provides more information about protection against indirect
contact in case of a short-circuit between hazardous live parts and protective earth.
Consideration shall be given to compliance with different type of system earthing (e.g. TN, TT,
IT or corner- earthed) as the short-circuit current to protective earth depends on the type of
system earthing.
NOTE Especially, the short-circuit fault current to earth is expected to be lower or equal to the rated output
current of the power output depending on system earthing.
For information requirements, see 6.3.7.

Add, after 4.4.5.2.7, the following new subclause:
4.4.6 Motor overload and overtemperature protection
4.4.6.1 Means of protection
A motor of a PDS shall be protected against overtemperature. Depending on the application
of the motor, one or more of the following means of protection for each motor driven shall be
selected by the PDS manufacturer:
a) thermal or electronic overload relay that complies with the applicable requirements in
IEC 60947-4-1;
b) a CDM/BDM with electronic motor overload protection according to 4.4.6.2, which might
include
i) thermal memory retention according to 4.4.6.3, and/or
ii) speed sensitivity according to 4.4.6.4.
c) a CDM/BDM with monitoring and automatic reduction of motor current based upon a
signal from a thermal sensor mounted in or on the motor according to 4.4.6.5;
d) an embedded motor thermal protection which disconnects the motor;
e) information in accordance with 6.3.8.1.
NOTE 1 a) and d) are the only possible motor overload protections in the case that several motors in parallel are
supplied from the same CDM/BDM motor power output.
