Safety Precautions
Ensure that the selected place is free of electric noise, etc.
Precautionary measures (prevention of noise generation, etc.,) must be taken for other
equipment to prevent the machine from malfunctioning.
Do not expose the machine to combustible or corrosive gas.
Select a place free of lamp soot and dust.
Level the machine at the correct height, using a level vial.
The machine should be free of obstacles around it for easy maintenance.
When the openings of the conveyors in the PCB input or output section are too big,
some measures must be taken on the customer side to avoid any clearance according
to the condition of the conveyors in the input and output machi
nes and the condition of
both machines.
Power Supply
Confirm that the following power is supplied to the machine.
•
Voltage
: 200±20 V AC, 3-Phase
•
Apparent Power : Approx. 8 kVA or less
Fluctuating voltage and noise in the power line can have not only a bad influence on the
machine but also trigger a malfunction of the machine, causing an accident.
Take necessary measures to prevent the other equipment from generating noises.
The primary power supply must be prepared on the local site.
•
The grounding line (PE) must be connected first to the leading-in section of the
primary power supply
.
•
The 100
Ω
or less grounding must be provided, using a metal wire (Tensile Strength:
0.3 kN or more) or an annealed copper wire (Diameter: 1.6 mm or more).
•
When the ground line is connected, it must be longer than the other cables (L1, L2,
and L3), giving some leeway.

Safety Precautions

AKOE-ID
When an earth leakage breaker is used for the power supply to the machine, confirm
that it is a type of breaker that cancels the high-frequency element immediately after
the rated sensitivity current reaches 60 mA
or higher
.
•
PXH-1 Leakage Current: 30 mA or less
Generally
, an earth leakage breaker is not tripped when leakage current is less than 50%
of the rated sensitivity current. On the other hand, it may be tripped when leakage current
reaches 50% or more.
When the power source contains some high-frequency elements, leakage current
increases, causing an earth leakage breaker to malfunction even though the machine is in
the normal condition if the breaker is a type that cannot cancel high-frequency elements.
Air Supply
Supply dry and clean air (Pressure: 0.39 to 0.69 MPa (4 to 7 kgf/cm
2
)) that does not
contain moisture, oil, and dust to the machine.
When the supplied air contains much moisture, etc., the machine may not work normally
due to the moisture, etc., accumulated in the machine.
Note
Dry and Clean Air
Moisture : Dew Point -17°C or less (Atmospheric Pressure)
Oil : 0.1 mg/m
3
or less (ANR)
Dust : Solid 0.01 µm or less
Data Backup Operation
Data may become unavailable due to breakdown or mishandling of the machine.
It is strongly recommended that the compact flash memory card data be periodically
backed up with the network terminal (option).

Safety Precautions
Computer Viruses
When a program or data is corrupted abruptly, the computer makes unexpected system
behavior, or an abnormal window appears on the operation panel, the computer may be
infected with a virus.
Computer viruses are bad programs written to deliberately invade a computer system
without its user's permission or knowledge. They can perform a triggered event or corrupt
your precious data.
Antivirus programs are called "Vaccines" and used to remove or repair infected programs
and files.
A virus-infected computer may spread the virus to other computers through
communication systems or by sharing diskettes (data storage media) between different
computers.
Use a vaccine program to check if the built-in computer is infected with a virus if
necessary.
Keep in mind that a computer virus cannot be removed, depending on what type of
vaccine program you are using.
For this case, book the backup of data beforehand.
Power Failure
Instantaneous voltage drop due to power failure or lightning will cause the built-in
computer to break down and the basic and application programs to corrupt.
It is recommended that a DC uninterruptive power supply be used as a countermeasure
against instantaneous voltage drop.
Built-In Computer
A computer is built in the machine and used to control each internal mechanism of the
machine, save various data, and realize a user interface.
When the power switch of the machine is turned off while the computer is working
(computer being accessed), the computer may break down, causing the stored data and
application programs to corrupt.
Refer to "Power OFF Operation" in "Chapter 3 (Vol. 1: Guide)" for how to turn off the
power switch of the machine.
