NOTE!!!
When connection a faulty appliance to the test socket a hazardous voltage may occur when
mains is applied on accessible conductive parts not connected to the protective earth and on
the housing if the protective earth is out of order.
The leakage current, mains currents and power is measured via the test sockets.

5 Functional Description
5.1 Power supply
The transformers for the supplying the tester are protected by two internal fuses located next
to the transformers.
5.2 Internal memory
The measurements performed are stored in the internal memory. Appliance master data and
test data may be transferred to the PC. Appliance master data as well as the test profile may
also be uploaded from the PC to the tester.
5.3 Interface RS232
The PC is connected via a SUB-D 9 extension cable. An adapter USB/RS232 may also be
used.
Note: All pins must be wired through (1:1). Do not use a Null modem cable.
The baud rate is 19200 baud
The interface is galvanically isolated from the electronics and from the test sockets.
The firmware of the tester may be updated via the interface using a special update program.
A barcode reader may be connected to the interface to scan in ID numbers of the appliances
under test. The reader must be pre configured to 19200 Baud, 8 bits, no parity, 1 stop bit,
code 39. It may be connected toe the interface and the control codes may be scanned in.
A transponder reader may also be connected for scanning in the ID codes.
Note: The appropriate configuration must be made within the menu.
For printing out results a small printer may be connected to the interface.
5.4 Display and Keyboard
The display and keyboard are supplied by their own circuitry.
5.5 Fuses
F1, F2, F3 = mains fuses, T 16 A , 6,3x32, 250 V, for all 16 A testing sockets,

SAFETYTEST 3S Manual SAFETYTEST
SAFETYTEST GmbH 16 April 2006 Page 10 of 18
F4 = fuse F 250 mA, 250V, 5x20, for resistance measurement,
NOTE!!!
Please take note of the warnings of chapter 2.
6 Testing the Mains Connection
The person responsible for the electrical installation is responsible for the safety of the power
system to which the tester is connected.
The test of the installation is not part of the appliance test. Nevertheless the tester allows a
Note: This is not a complete test as required by IEC 16557.
The test checks if there is a voltage on the N conductor against the PE conductor. Also the
mains voltages are displayed. In addition the display indicates a clockwise or anti clockwise
phase rotation of a three phase system.
Note: • If the mains connection is faulty a message “Test PE connection” is
displayed on the display. Further tests may only performed after the power
system has been repaired.
• If the tester is supplied from an AC system an indication may appear that the
plug connection has to be reversed. Follow this before testing.
7 Connection test
The first menu displays the phase voltages, the phase rotation and an indication of the
potential difference between the PE and N conductors of the power system.
7.1 AC Supply
If the message “Reverse connection” appears then reverse the polarity of the Schuko plug
connected to the power system.
