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.

Grounding and power connection
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. To avoid
electric shock the power cord protective grounding conductor must be connected to ground.
System GND
The system is connected to GND via the earth wire of the connected mains power cable for the generator and the
EUT supply. A separate GND wire from the reference GND plane to the building earth point may be useful to
avoid interferences to other areas.
EUT GND
Ensure that a reliable return path for the interference current is provided between the EUT and the generator.
The GND wire from the generator to the reference GND and must be designed as a low inductance connection
suitable for high frequencies. The reference ground plane and the ground connections to the instruments, as
described in the relevant test standards, serve this purpose well.
Protection (optional)
A proposal is to separate protection of the EMC system with filters, insulation transformer or fault current
protection and other measures may be useful for the EMC installation. The advantage is the separation of the
EMC system from all other installation.
A shielded room with adequate filters may be the best solution for avoid unwanted conducted and radiated
interference to other areas.

Mains Switch, fuse holder and power input
To replace a fuse:
1) Disconnect the mains cable
2) Pull the fuse holder out of the connector
3) Remove the damaged fuse(s)
4) Insert 1 or 2 fuses (4 A / 115V and 2 A / 230 V slow blow)
5) Replace the fuse holder
6) Plug the mains cable into a power outlet with a solid ground
connection
7) Switch the system on and operate as instructed in this manual

Connecting the compact NX5 system to the ground reference
Connection to reference ground
Connection to reference ground
For burst tests, the generator must be placed on a ground
reference plane which is connected to ground.
A low inductive high frequency ground connection between the
test system and the ground reference plane (GRP) is absolutely
essential for performing burst tests correctly.

Safety circuit
The safety circuit locks the system and enables the
generation of the high voltage impulses in the
generators.
Design
Each device that has internal relevant high voltage
unit, includes a safety circuit. The safety circuit works
like an “open collector circuit”, where the external
safety loop must be closed for switch on the high
voltage.
Safety circuit closed
The device will generate high voltage pulses after start
Safety circuit open
The device will switch off the high voltage and
discharges the high voltage circuit

Warning Lamp
The warning lamp offers a voltage free contact that
indicates the status of the generator system.
Design
Each device with warning lamp function can short
thewarning lamp contact. An external powered relays
max. 60 V / 2 A controls the lamp. The user is
responsible for the warning lamp power supply

EUT Power supply and 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 61010-1:2001.
Dimensioning of the mains supply and rating of fuse protection of the AC or DC power supply must conform with
local electrical codes and EUT requirements. Inappropriate arrangement, mounting, cabling or handling of the
EUT or ground can reduce or negate the effectiveness of the compact NX5’s safety features.
3.4.1.
Notes on protective devices which need to install the operator
There are two different protective devices in a mains distribution system for safe operation.
A Fault current protection: A residual-current device (RCD), or residual-current circuit breaker (RCCB)
is an electrical wiring device that disconnects a circuit whenever it detects that
the electric current is not balanced between line and the return neutral. In
normal circumstances, these two wires are balanced, and any difference
current usually indicates a short circuit or other electrical anomaly like a surge
impulse is present.
B Circuit breaker protection: A circuit breaker is an electrical switch designed to protect an electrical
circuit by overload or short circuit. Its basic function is to detect a fault
condition and interrupt current flow.
3.4.1.1.
Fault current protection
The standards recommend decoupling and filter capacitors to PE for decoupling surge pulses. This is the reason
for tripping fault current protection relays that interrupt the mains to the EUT supply. For eliminate the
circumstance use one of the following options:
Remove the fault current protection
This solution does not limit the current to PE. The surge test as other EMC tests with higher currents to PE are
possible. The user must take care to the circuit with no fault current protection. Only trained professional people
are allowed to perform such tests. Some countries do not allow to operate without fault current protection.
Using of insulating transformers
An insulating transformer separates the circuit from the test circuit. The Fault current detector (FI protection)
cannot detect the earth current in the EUT circuit.
The fault current safety detection function in the generator circuit is disabled. The user must respect
this circumstance. For a safe operation he must follow the electrical rulers.
Behind the insulating transformer the neutral and PE must be connected for a proper phase synchronization of
the generator. In case of a 3-phase system the user must perform similar.

3.4.1.2.
Fuses for EUT with smaller nominal currents
The EM Test pulse generators have no built in fuse for the EUT power supply. It is in the scope of responsibility
of the user to protect the EUT external for the rated current.
The design of the external fuse must be match the following rules:
- fuse dimension must be equal or smaller than the rated EUT current of the connected test
generator
- fuse must be designed for protect the connected EUT device under test in malfunction
Example of external circuit breaker
Circuit breakers in the building are designed for 32 A. A circuit breaker box with 16 A protection is
installed between the building supply and the test generator.
Test generator and EUT are now fused for 16 A rated current

Phase indicator
The phase indication shows the correct connection of the supply to Phase and Neutral input of the compact
NX5. For the generator hardware both, L and N paths are potential free and a reverse connection is not relevant
for the generator operation.
For EUT where it is important that phase and neutral are correct, the LED indication shows the correct phase
connection.
