Å Enter the measured value into the test report.
If the measured value is < 100 mA, the machine has passed the high-voltage test and can be
released. If the measured value is greater, the error must be eliminated. and the test repeated.
2.5 PE conductor test
2.5.1 Permissible impedance values for the PE conductors
The PE test is used to test the continuity of the PE conductor system by means of a loop
impedance measurement to IEC 60364-6-61, 612.6.3. 2
PLEASE NOTE:
All the electrical connections must be fully installed on the machine, including those for the power
supply. 2
The impedances measured between the PE terminal and the test points must not exceed the
values shown in the following table. 2

2.5.3 Carrying out the PE conductor test
Å Measure the impedance of the PE conductor (yellow-green). Measure at the point furthest from
the PE conductor infeed point. The test duration should be at least 10 seconds.
Å Document the measured values in the test report.
Å Compare the measured values against those in table 2 - 1 on page 75.
Å Record whether the test was passed or not.
Å The machine may be released if the test is passed.
Å If the test is not passed, the error must be eliminated and the test repeated.

3.1 Versions of the affected power supply units
This section describes how to convert the power supply units on SIPLACE S-20/
S-23HM/S-25HM/F4/F5 and F5HM placement machines, the changeover table and wafflepack
changer. This will allow the power supply units to be adapted to the supply networks in individual
countries. 3
These instructions apply to machines with the following power supply unit releases: 3
