1 IMPORTANT SAFETY PRECAUTIONS
The following is very important matters in order to safely handle this product (called unit
hereafter). Read carefully them and strictly observe them.
1. Use of this unit in an explosive area such as "No fire" area etc. is
prohibited. If used in such an area, it is liable to cause combustion or
ignition due to discharge.
2. Any person who has an implanted pacemaker in the body should not
operate this unit. Furthermore, such a person should not enter the
test area while this unit is operating.
3. When connecting cables and carrying out settings, place the unit in
the STOP conditions beforehand, otherwise, an electric shock due to
high voltage may be caused. Even in the STOP conditions, keep a 5
seconds lapse as residual voltages may exist.
4. Before connecting the equipment under test (called EUT hereafter),
check to see that the EUT LINE breaker is off, otherwise an electric
shock due to supply power voltage may be caused.
5. An isolation transformer is indispensable for power supply input to
the EUT. Power supply connection to the EUT LINE INPUT shall be
always done trough an isolation transformer.
6. Fully put in each coaxial connector and make sure connection by
rotating it clockwise until a "click" is heard.
7. Be extremely careful of an electric shock due to the generated pulses
and power supply to EUT.
8. Be sure to go through Section 3 Basic Safety Precautions before use
listing safety precautions for test set-up, connection and execution
of test.

3 BASIC SAFETY PRECAUTIONS
3.1 WARNING SIGNS AND THEIR MEANINGS
Means a warning.
If such a danger is not avoided, a potential
danger which may result in a death or
serious injury will be caused.
Means a caution.
If such a danger is not avoided, a potential
danger which may result in a minor or medium
degree of injury will be caused.
3.2 BASIC SAFETY PRECAUTIONS
1. Use of this unit in an explosive area such as "No fire" area etc. is
prohibited. If used in such an area, it is liable to cause combustion or
ignition due to discharge. [Precautions for human body and
environments]
2. Mishandling and careless operation of this unit will result in a deadly
injury. [Precautions for human body, operation, environment and
connection]
3. Any person who has an implanted pacemaker in the body should not
operate this unit. Furthermore, such a person should not enter the
test area while this unit is operating. [Precautions for human body
and operation]
4. Before connecting the EUT, check to see that the EUT LINE breaker is
off, otherwise an electric shock due to supply power voltage may be
caused. [Precautions for human body and connections]
5. When connecting cables and carrying out settings, place the unit in
the STOP conditions beforehand, otherwise, an electric shock due to
high voltage may be caused. Even in the STOP conditions, keep a 5
seconds lapse as residual voltages may exist. [Precautions for human
body and connection]
6. Fully put in each coaxial connector and make sure connection by
rotating it clockwise until a "click" is heard. Insufficient connection
leads to unwanted discharges inside the coaxial connectors.
[Precautions for human body and connection]
7. Be extremely careful of an electric shock due to the generated pulses
and power supply to EUT. [Precautions for human body and
connection]

6
8. When conducting coupling tests to the EUT LINE, the signal ground
of the HV pulse generator circuit and one line (phase) of the EUT LINE
may be connected, causing a shock hazard if the users touch the
outer conductor of the HV coaxial connectors.
In addition, if the outer conductor of the HV coaxial connectors is
connected to any grounded subject, leak current will flow, tripping the
ground fault interrupter embedded in the facilities.
To avoid these two types of events, use of an isolation transformer is
indispensable. Be sure to connect the EUT LINE INPUT to the isolation
transformer secondary. [Precautions for human body and connection]
9. Any other connection than the supplied SG short plug shall not be
connected to the SG connector of this unit. Wrong connections may
apply HV pulses to the ground plane, causing a shock hazard.
[Precautions for human body and connection]
10. The AC INPUT (AC inlet) terminal on the rear panel has a conductor
for safety grounding connection. This unit shall be connected to a
properly grounded service outlet through the AC INPUT. When this
unit is not grounded through the AC INPUT, PE terminal positioned
next to it shall be used. [Precautions for connection]
11. High voltages exist inside the unit. Never open the covers.
[Precautions for human body]
12. NOISE LABORATORY and its sales agents shall have no liability
against any accident resulting in injury or death, any damage to
equipment or any resultant damage thereof which is caused by abuse
or careless handling of this unit. 【Precautions for human body,
operation, environments and connection】

7
13. The SG terminal provided on the front panel of this unit functions as
the signal reference ground for testing. The PE terminal (EUT) is for
the protective earth conductor for the EUT. The protective earth
terminals for this unit itself are the AC inlet earth pin (AC INPUT) and
PE positioned in close proximity. These SG, EUT PE, simulator PE are
independent each other. When conducting tests, make connections
according to Section 9 test Set-up. [Precautions for operation and
connection]
14. The test rig used in conjunction with this unit should be insulated
against a minimum voltage of 8kV (when the built-in 50Ω terminator
disconnected from the test circuit). [Precautions for environments]
15. During test, high level of electromagnetic radiation may be generated
depending on the type or nature of the EUT and thus causing
interference with nearby electronic equipment and radio
communication equipment. In such case, the user may have to take
measures such as a faraday case, shielded room, shielded cable and
so on. [Precaution for environments]
16. The supplied SG short plug shall not be connected to any other terminal than
L1, L2, L3, N, PE and SG HV coaxial connectors. Connection to wrong terminals
may damage the unit. [Precautions for operation and connection]
17. Be sure to connect the ground plane to the safety ground.
[Precautions for operation and safety]
18. To ensure safety in operation, use the accessories and optional
equipment supplied by our company. Use of others may degrade the
safety and performance of this unit. [Precaution for handling and
safety]
19. Do not use nor keep the unit in a hot or cold environment (Operating
temperature: 15°C~35°C/Operating humidity range: 25~75%) otherwise,
the unit may be damaged or only exhibit limited performance.
[Precaution for environments]
20. If condensation is found, fully dry the unit before operating it,
otherwise, the unit may be damaged or only exhibit limited
performance. [Precautions for environments]
21. Do not drop the unit or do not give strong shock to the unit.
[Precaution for handling]
22. When installing the unit, do not block the vent. [Precaution for
environments]
23. Do not apply voltage exceeding the rated voltage range. [Precautions
for installation and connection]

8
24. Only a service engineer authorized by our company should perform
repair, maintenance work and internal adjustment. [Precaution for
handling and safety]
25. Do not wipe off the body and peripheral equipment with thinner,
alcohol or other solvent. When the unit is dirty, soak a cloth in a
detergent, wring it and wipe the unit with this cloth. Using solvents
may spoil the appearance. [Precautions for handling]
26. The coaxial connectors used for this unit is of NoiseKen original
design. Use of other type of connectors may cause electric shock
hazards or malfunctions of the unit. [Precautions for handling and
safety]
27. When conducting powered EUT testing, be sure to turn ON this unit
and check to see that the power lamp is on. Testing in OFF status
may cause damage or deteriorate some components in this unit due to the
temperature rise since the cooling fan does not work. [Precautions for
handling and safety]
28. Read carefully and strictly observe the instruction manuals of this unit and of
the impulse noise simulator. [Precautions for handling and safety]
3.3 WHEN WARNING LABEL IS MISSING
1. When warning label is lost, or peeled off or dirty, put up a new one for
extra safety.
2. When warning label is lost, contact our company's sales dept. or
maintenance dept. for issuance.
