Installation put in service
This chapter includes a checklist with steps that should be taken before the compact NX5 generator is switched
on and put into operation.
3.1.
Safety instructions for installation and initial installation
National regulations in installation and operation of electrical equipment must be respected.
WARNING The compact NX5 test system is not suitable for use in an explosive atmosphere.
WARNING
Connect the EUT only after the initial system setup has finished.
3.1.1. Qualifications of the staff
Basic knowledge of electrical engineering and electromagnetic compatibility is required to service the unit. The
national regulations for installation of electrical equipment as well as the safety at work of electrical equipment
must be known to the user.
3.1.2. Installation
The Compact NX5 system conforms to protection class 1. Local installation regulations must be respected to
ensure the safe flow of leakage currents.
WARNING
Operation without a ground connection is forbidden!
Two independent ground connections are necessary - one for the test system and one for the EUT. These must
be connected back to the local permanent installation or to a fixed, permanent ground conductor.
Operate the equipment only in dry surroundings. Any condensation that occurs must be allowed to evaporate
before putting the equipment into operation. Do not exceed the permissible ambient temperature or humidity
levels. Use only officially approved connectors and accessory items.
Ensure that a reliable return path for the interference current is provided between the EUT and the generator.
The ground reference plane and the ground connections to the instruments, as described in the relevant test
standards, serve this purpose well.
The test system may only be opened by a qualified specialist upon specific instruction given by the manufacturer.
The equipment works, on principle, with two independent power supplies, one for the generator and one for the
EUT. The compact NX5 must be disconnected from both sources before any modifications to the test setup are
undertaken. Besides the mains connections themselves, certain components also operate at high voltages, and
are not provided with any form of extra protection against accidental contact.
The system complies with the safety requirements of IEC/EN 61010-1 (Safety requirements for electrical
equipment for measurement, control and laboratory use).
It is the user
’s responsibility to ensure that the test rig does not emit excessive electromagnetic interference (EMI)
that might affect other equipment. The test system itself does not produce any excessive radiation; however, the
injection of interference pulses into the EUT can result in the device and/or its associated cables radiating EMI.
To avoid radiating unwanted interference the standards organizations recommend that the test setup be located
in a Faraday cage.
Since the purpose of the test system is to produce interference signals for interference immunity testing, the
requirements in the IEC/EN 61000 series concerning limiting the radiated EMI can only be complied with by
operating the test system inside a Faraday cage.
