6. Our company and sales agents shall have no responsibility for any accident
resulting in injury or death, any breakage or resultant damages due to
irresponsible handling. 【Precautions for human body, operation, environments
and connection】
7. When lowering the voltage setting of this unit with VOLT ADJ control,
discharge extra energy, otherwise causing a danger. (High voltage remaining
in the condenser in this unit will not lower even if VOLT ADJ control is
operated, unless high voltage is discharged.) To discharge extra energy,
turn off the high voltage circuit (by pressing HIGH VOLT OFF switch) or
press START switch and then discharge until the meter indicates the desired
voltage setting. If this operation is omitted, the operator may receive an
electric shock. 【Precautions for human body and operation】
8. Never fail to watch equipment while this unit is operating. When leaving
this unit, check that the voltmeter indicates “0V” and the high voltage circuit
of this unit is turned off by pressing HIGH VOLTAGE CIRCUIT OFF SWITCH
beforehand. Otherwise, a third person or equipment related to the test may
be exposed to a danger. 【Precautions for human body, operation and
environments】
9. Do not connect a cable etc. to any terminal unnecessary for setting a test.
Do not mistake cable setting or connection. Otherwise, you may receive an
electric shock or the internal unit of this unit and equipment connected to it
may be damaged. 【Precautions for human body, operation and connection】
10. When conducting a DC line injection test, turn off power supply to EUT and
DC ON switch (breaker) of this unit before connecting EUT or DC input cable
to this unit. Otherwise, the operator may receive an electric shock by
power supply to EUT. 【Precautions for human body and connection】
11. Connect each connector and cable securely. Otherwise, you may receive
an electric shock or the internal unit of this simulator and equipment
connected to it may be damaged. 【Precautions for human body and
connection】
12. To ensure safety operations, use the standard and optional accessories
supplied by NOISEKEN.
13. When this unit is not used, remove the supplied switch key and keep in a
safe place

7. HOW TO CONNECT EQUIPMENT
Thoroughly read Par. 5 “Fundamental Safety
Precautions for Safety Performance” before doing
connection and starting a test.
7-1 Preparation
1) Install the simulator on a level floor and put a stopper under the caster.
When installing this unit, do not block the ventilating
opening.【Precautions for environments】
2) A radiation fan is provided on the top of the simulator. Check that nothing is
blocking the fan. Adjust the 50/60HZ SELECT SWITCH ➋to the
frequency of commercial power supply before using
this unit. Continuous use by mistake will result in
a trouble or burn of the power supply. 【Precautions
for connection】.
3) Set the 50/60Hz select switch ➋to the position matching the frequency of the
commercial power supply.
7-2 Connection to the equipment being tested
Connect the equipment being tested to the simulator by referring to the figure in
page. 16. In this case, however, use a cable with sufficient resistance to voltage
and current. When performing DC line injection test ,turn off the
power supply for the EUT and DC ON SWITCH
(breaker) before connecting this unit to the EUT and
DC input cable. Otherwise, you will receive an
electric shock by power supply for EUT.
【Precautions for human body and connection】
Connect each connector and cable securely.
Otherwise, you may receive an electric shock or the
internal unit of this simulator and equipment
connected to it may be damaged. 【Precautions for

7. Connection of the simulator
1) Connect the plus side power input terminal of the equipment being tested to
the SURGE OUT TERMINAL ⑮of the simulator.
2) Connect the minus side power input terminal of the equipment being tested to
the SURGE G TERMINAL⑭of the simulator.
3) Pass the cable through the hole provided on the acrylic door on the front panel
and tightly close the door. If the acrylic door is left open, the safety device
will actuate to make the HIGH VOLTAGE ON SWTICH③inoperative.
7-3 Connection with the power supply for driving the
equipment being tested
Connect the power supply for driving the equipment being tested to the simulator
in the following manner by referring to the figure in page 16. In this case,
however, use a cable with sufficient resistance to voltage and current. Use of a
thin, long cable may produce a disordered surge waveforms. So, a thick and
short cable (2mm2and over) is preferable.
When performing DC line injection test ,turn off
the power supply for the EUT and DC ON SWITCH
(breaker) before connecting this unit to the EUT
and DC input cable. Otherwise, you will receive
an electric shock by power supply for EUT.
【Precautions for human body and connection】
1) Turn off the DC BREAKER⑩.
Connect each connector and cable securely.
Otherwise, you may receive an electric shock or
the internal unit of this simulator and equipment
connected to it may be damaged. 【Precautions
for human body and connection】
2) Connect the plus side of the power supply for driving the equipment
being tested to the DC IN terminal⑬of the simulator.
3) Connect the minus (ground) side of the same power supply to DC G terminal⑫
of the simulator.
4) Pass the cable through the hole provided on the acrylic door on the front panel

8. OPERATION
Thoroughly read Par. 5 “Basic Safety Precautions for
This Simulator” before doing connection and
starting a test.
8-1. Power ON
1) Insert the supplied switch key into the POWER SWITCH⑦and turn the
switch key clockwise by 90 °. Thus, the power is supplied to the simulator and
the POWER LAMP⑥lights up.
2) When the DC BREAKER⑩is turned on, the power is supplied to the
equipment being tested.
8-2. Selection of the surge waveform
1) The name of the surge waveform specified in JASO Standard is engraved on
the top of the respective keys of the SURGE WAVEFORM SELECT
SWITCHES⑯. The surge waveform is selected by pressing any of the
SURGE WAVEFORM SELECT SWITCHES⑯. When the power is turned
on, the surge waveform mode is initialized to Class A-1 waveform.
8-3. Buzzer setting
An end buzzer and a surge out buzzer are built into the simulator.
1) The surge out buzzer actuates at an interval of 30 seconds during surge
application.
When the SURGE OUT BUZZER actuates, surge is
output from SURGE TERMINAL⑮
⑮⑮
⑮. Be careful
with electric shock.
2) The end buzzer actuates when SURGE APPLICATION SET COUNTER ⑩
stops counting and surge application is completed. The buzzer sound
continues until END BUZZER STOP SWITCH⑨is pressed. While the
buzzer sound is produced, the lamp provided inside this switch lights up. The
end buzzer can be set with END BUZZER ON/OFF SWITCH⑧. When this
switch is set to the ON position, the lamp provided inside the switch lights up
and a buzzer sound is produced at the end of the test.

8. Operation Procedure
8-4. Surge voltage setting
1) Make sure that the acrylic door on the front panel is closed. Then, turn the
VOLTAGE ADJUST KNOB①fully counterclockwise (0V).
2) Turn on the HIGH VOLTAGE ON SWITCH③. In this case, if the lamp
inside HIGH VOLTAGE ON SWITCH ③lights up, the surge generation
circuit is on stand-by. On the other hand, if it does not light up, check Step
1) again. When the acrylic door is not closed, the safety device actuates to
make HIGH VOLTAGE ON SWITCH ③inoperative.
Never fail to watch equipment while this unit is operating.
When leaving this unit, check that the voltmeter indicates “0V”
and the high voltage circuit of this unit is turned off by pressing
HIGH VOLTAGE CIRCUIT OFF SWITCH beforehand. Otherwise,
a third person or equipment related to the test may be exposed
to a danger. 【Precautions for human body, operation and
environments】
3) Next, set the peak value of the surge voltage in the no-load state by turning
the VOLTAGE ADJUST KNOB①while observing DIGITAL VOLTMETER⑲.
The JSS-003 employs an inverted L type circuit specified in JASO Standard
D 001-94 as a transient voltage generative circuit. Therefore, the set
voltage (charge voltage to the condenser) specified in JASO Standard is
equal to the peak value of the surge voltage (transient voltage) in the no-load
state. The maximum transient voltage Vp specified in JASO Standard and
the maximum set voltage of the JSS-003 are as shown in Table 1 below :
Class of test
Set Voltage (V)
Maximum set voltage Vp (V) of JSS-003
