15.9 Testing in Accordance with DIN EN 60950
Tests for safety class I and II data processing equipment and office machines.
The following measurements can be performed in accordance with the
above mentioned standard:
• Protective conductor R
PE
Test current: : 25 A AC (Feature G01 or SECUTEST SIII+H )
•
Testing of dielectric strength by applying DC high voltage (1.5-fold value)
(Prerequisite: Feature F02 or SECUTEST SIII+H)
• Device leakage current I
According to DIN EN 60950, data processing equipment and office ma-
chines must be subjected to a device protective conductor test and a
high-voltage test before they are brought into circulation. This applies to:
• Safety class I devices for all exposed, conductive parts which are
accessible to the user, and which are not connected to the protective
conductor
• Safety class II devices (totally insulated devices) for all exposed,
conductive parts which are accessible to the user
• Housing leakage current
with the mains plug poled in both directions
Connecting the Device Under Test
õ Connect the test instrument to the mains, and the device under test to
the test socket at the test instrument.
Check connection parameters and start test.
To Socket This is the default setting. Refer to chapter 7 on page
17 for other types of connection.
Class If the DUT has been connected to the test socket,
safety class recognition is performed (SC I or SC II).
Otherwise, the safety class must be specified manu-
ally.
Type A specific DUT type can be selected from a list of
devices under test, if these have been entered in the
setup menu.
ID No. An individual serial number (up to 10 characters) can
be entered with the keypad at the (P)SI module
(accessory), or can be read in with a barcode scan-
ner (accessory).
If an incorrect entry is made: Only complete lines can
be deleted, and deletion is only possible with the
key at the instrument.
Setup Refer to chapter 15.2 on page 37 regarding setup of
the measuring sequence.
