Installation
The NSG 3150 test 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!
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. Since the
instrument works, on principle, the NSG 3150 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.
Take care to have access to all connectors for disconnect them in no time in case of emergency.

Installation of an EUT power switch
The EUT input should be connected through a properly rated power switch device, which should be located close to the test
setup. In order to ensure easy and quick access to the EUT power, the switch should be clearly and visibly labeled as "EUT
power ON / OFF".
The in-house power distribution must be equipped with a proper circuit breaker and an emergency off button as per IEC 61010-
1.
WARNING - Operation without a ground connection is forbidden!

Dangers concerning the EUT
WARNING - Users must be aware of the following dangers that can occur during testing:
▪
▪
Local burning, arcing, ignition of explosive gases.
EUT supply current surge caused by a flashover or breakdown resulting from the
superimposed high voltage.
Disturbance of other, unrelated electronics, telecommunications, navigational systems
and heart pacemakers through unnoticed radiation of high frequency energy.
In the test system the interference voltage, corresponding to the level called for in the
relevant test specification, is superimposed also on the EUT's protective earth
conductor. Earth contacts or pins (e.g. as in German and French mains plugs) as well as
the EUT earth itself can therefore be at an elevated voltage level that would make
touching dangerous. In many power connectors even the screws are linked to the
protective earth.
EUTs are often functional samples that have not yet been subjected to safety tests. It is
therefore possible that the EUT could be damaged by internal overloads or may even
start to burn.
As soon as the EUT shows signs of being disrupted the test should be stopped and the
power to the EUT switched off.
