2.3.3 Performing the insulation test
Create a test set-up as illustrated in figure 2 - 3.
Follow the instructions in the manual for the testing device.
Measure the insulation resistance at 500 VDC.
Enter the measured value into the test report.
If the measured value is > 1.0 MOhm, the machine has passed the insulation test and can be
released. If the measured value is smaller, the error must be eliminated and the test repeated.

2.4 High-voltage test
2.4.1 Minimum durations and voltages for the high-voltage test
The electrical system must withstand a test voltage applied between the conductors of all the
power circuits and the PE conductor system for at least 10 seconds. 2
The test voltage must 2
– be twice the rated voltage for the electrical system or 1000 VAC (Canada: 1500 VAC), which-
ever is the higher.
– have a frequency of 50/60 Hz and
– be powered by a transformer with a minimum rated output of 500 VA.

WARNING 2
Parts of the system that are not rated for the test voltage must be disconnected. This particularly
applies to the monitor. 2

2.4.3 Performing the high-voltage test
– Disconnect the monitor.
– In the distributor box, connect the three-phase AC socket or socket with earthing contact to the
power cable for the machine, component table or MTC/MTC2. The test set-up is shown in fig-
ure 2 - 3
.
RISK OF DEATH 2
To protect the test set-up, you will need 2
a barrier chain
a red flashing light to signal the high-voltage tests and keep unauthorized personnel away from
the system.
Switch on the testing device and measure the equivalent leakage current with the following set-
tings:
- 1000 VAC (Canada 1500 VAC)
- Test duration 10 sec.
Measure the equivalent leakage current (active or apparent current).

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 imped-
ance 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 val-
ues shown in the following table. 2
