1. SAFETY ADVICE
1.1. General
■8VHRIWKH&’1LVUHVWULFWHGWRDXWKRUL]HGDQGWUDLQHGVSHFLDOLVWV
■In the fault case dangerously high voltage may be on the housing.
■The coupling network housing must be properly grounded (earthed).
■Operate the equipment only in dry surroundings.
■This instrument is not designed for use in an explosive atmosphere.
■Only approved accessory items, connectors, adapters, etc. are to be used to ensure safe operation.
■The setup must offer insulation protection against voltage which is at least equal to the pulse voltage.
■The pulse voltage must not be able to find its way to ungrounded metallic objects even if the EUT is faulty
or fails.
■Depending on the type of EUT and especially on its cabling, a considerable amount of interference can
be radiated which could affect nearby systems and radio communication. These environmental interfer
ence effects to be controlled by the user through the use of suitable measures such as a Faraday cage,
shielded cable runs, etc.
1.2. Applicable safety standards
Development and manufacture of the instrument complies with ISO 9001. The product conforms with the
UHTXLUHPHQWVRIWKH/RZ9ROWDJH’LUHFWLYH/9’(&EDVHGRQ’,1(1
1.3. Safety symbols used on the product
WARNING: Improper or careless handling can be fatal!
Use of the CDN is restricted to authorized and trained specialists
Protective earth (earth terminal)Attention: Refer to manual
1.5. Test execution
The test area must be organized so that no unauthorized persons have access during execution of a test. If
a safety contact (interlock) is used as a means of access control to the test area (e.g. Faraday cage), then an
additional contact in series with any hazardous voltages or currents is necessary to provide protection
for parts of the EUT that are in danger of being touched.
EUTs, together with their accessories and cables, are to be considered live during a test. The test generator
must be stopped and the EUT supply interruptedbefore any work can be performed onthe EUT. This can often
be achieved by opening the interlock circuit, depending on the type of generator in use.
The EUT is to be tested only in a protective cage or under a hood which provides protection against electric
shock and all manner of other dangers pertaining to the particular EUT.
The safety instructions for all instruments and associated equipment in the test setup are to be observed.

With a surge test voltage of 2 kV is the maximal residual voltage at the AE port only 65 V due to the excellent
decoupling network. Additional decoupling elements are not required to protect the auxiliary equipment
(AE). The high decoupling provides an AE independent pulse shape for the EUT testing. A high measurement

4. APPLICATION
4.1. Setup
Each test setup should be carefully planned. All the equipment should be securely positioned, and all cables
should be securely connected.
Caution: The safety advice given in Section 1 and in the generator manual
must be observed. The EUT and the wiring should be handled only
when the generator is not active.
