5.4.4 AS-i earth-fault detector
Replace the existing first and second paragraphs by the following two new paragraphs:
In accordance with IEC 60204-1, insulation faults on any control circuit shall not cause
unintentional starting, potentially hazardous motions or prevent stopping of the machine. To
fulfil this requirement, IEC 60204-1 indicates that control circuits that are not connected to the
protective bonding circuit shall be provided with an insulation monitoring device that either
interrupts the circuit automatically after detecting an earth fault or indicates an earth fault to
initiate a signalling at the machine.

– 4 – IEC 62026-2:2008/AMD1:2019
 IEC 2019
If an AS-i network is used to control potentially dangerous movements of a machine and
IEC 60204-1 applies, an insulation monitoring device shall be installed. If the AS-i network is
composed of separate parts that are isolated from each other, an insulation monitoring device
shall be used for each isolated part of the network.
Table 15 – Connection and wiring identification
In existing footnote a, replace "IEC 60947-5-2" with "IEC 60947-5-2:2007/AMD1:2012".
8.3.2 AS-i earth fault detector
Replace the existing third paragraph by the following new paragraph:
The manufacturer shall declare the impedance range that can be detected by the earth fault
detector between ASI+ and ground and ASI- and ground. It shall be compatible with the
requirements for the detection of an insulation fault, in accordance with IEC 60204-1.
8.6.2 Immunity
Replace existing first dashed item of second paragraph by the following new dashed item:
– A. Normal performance within the specification limits and statistical maximum of one
disturbed master request or slave response per 30 transactions.
8.6.2.3 Conducted radio frequency disturbances
Replace existing text of this subclause (including the note) by the following new text:
This test shall be conducted with 3 V, in accordance with IEC 61000-4-6, and performance
criterion A shall apply.
NOTE The operating environment of these devices using an AS-i power supply with a decoupling network is
considered to be well protected against conducted radio frequency disturbances; therefore, testing with 3 V is
sufficient.
9.1.2 Type tests
Insert the following new paragraph after the existing dashed items list:
EMC tests of the AS-i network shall be conducted in accordance with 9.5.9.
9.5.4.3.2 Test procedure with current probe and oscilloscope (Figure 86b)
Replace the existing first sentence of the second paragraph with the following new text:
Switch S1 allows to provide the AS-i slave either with the signal from the master (to switch the
slave in the desired state) or with the a.c. sinus signal to determine the impedance.
9.5.9.1 Test conditions
Replace the existing first paragraph by the following new paragraph:
Unless otherwise stated, the tests shall be carried out on all AS-i-devices addressed in this
document at an ambient air temperature of 23 °C ±5 °C.
Change the existing reference in the 4th paragraph under b) to read:
For master:
 IEC 2019
in accordance with 9.6 without repetition of any message in case of a fault.
9.5.9.5 Emission requirements
Replace existing text of this subclause by the following new text:
The tests shall be performed in accordance with the classification of equipment given in
Clause 5 of CISPR 11:2015, CISPR 11:2015/AMD1:2016 for group 1, class A devices and in
accordance with 8.6.3. The test levels specified in Clause 6 of CISPR 11:2015,
CISPR 11:2015/AMD1:2016 shall apply together with the test methods specified in Clause 7
of CISPR 11:2015, CISPR 11:2015/AMD1:2016.
A.4.5.3 S-7.E – Semiconductor motor control devices
Replace the existing note by the following new note:
NOTE When the motor starter is hybrid (semiconductor and electromechanical), it is considered as a
semiconductor starter (3.4.1 or 3.4.2 of IEC 60947-4-2:2011).
