EFT/ Burst Generator PEFT Junior 1
1. Description
1.1 Introduction
The PEFT Junior test system, enables electromagnetic immunity testing in accordance with the
standard IEC 1000-4-4 (IEC 801-4).
The built in single phase mains filter enables coupling of EFT / Burst into the EUT mains supply
with minimum disturbance to the general mains.
HAEFELY
CONTROL UNIT
HAEFELY
PEFT.1
Fig. 1.1
The equipment is controlled by an integrated microprocessor control unit ( P90 ).
In order to conduct three phase tests in accordance with the standard IEC 1000-4-4, it is
necessary to use an external coupling filter. For example the FP-EFT 32.1 is a three phase filter
that can be controlled directly from the PEFT Junior mainframe.
Tests in IEC 1000-4-4 which require coupling of the EFT / Burst into data and communication
lines, can be achieved using the capacitive coupling clamp type IP4A.
The test system can be made fully automatic, by using the optional interface type RC 730 for
RS232 and IEEE communication with the WinPATS software package.

2. Safety
2.1 Safety standards
The generator has been constructed in accordance with IEC 348 and IEC 1010: Safety
requirements for electronic apparatus.
This user manual contains information and warnings that must be heeded by the user for safe
and efficient use of the generator.
2.2 Environmental conditions
The generator contains high voltage circuits in a very small volume, this defines the
environmental conditions under which it may be operated.
Temperature 15 °C to 35 °C
Relative humidity 45 % to 75 %
Atmospheric pressure 86 kPa to 106 kPa (860 to 1060 mbar)
Absence of Frost, dew, rain,
condensation, water
infiltration, direct sun
Tab. 2.2
The generator must only be used in dry rooms. In the case of visible condensation, the generator
must be dried before use.
Under certain conditions sparks can be produced by the EUT or generator. Because of this the
generator must not be used in an area where an explosion hazard exists.
WARNING
Persons with heart pace makers must not be in
the area when the generator is operating

EFT/ Burst Generator PEFT Junior 9
2.3 Operating precautions
The generator produces high volatges, it is essential that the following basic safety instructions
be followed:
Do not approach the EUT during testing. Accesss to the EUT during operation
can be prevented by use of the safety circuit.
Never touch high voltage cables or connections during operation.
When handling the EUT, the high voltage and any supply to the coupling filter
must first be switched off.
For any service inside the generator, first disconnect the mains.
Tab. 2.3
For safety reasons, the generator must only be connected to an earthed mains supply.
2.4 Electromagnetic compatibility
The EUT may radiate electromagnetic energy. The local rules and regulations must be observed
with regard to this stray energy.
The PEFT Junior should not be placed close to sensitive measuring instruments.
The PEFT Junior satisfies the requirements of the following immunity tests:
Electrostatic discharge level 4 (IEC 1000-4-2)
Electric fast transients and burst level 3 (IEC 1000-4-4)
Surge level 3 (IEC 1000-4-5)
