Safety Precautions
Precautionary Measures before Installation
If the machine is installed in unsatisfactory environmental conditions, it may malfunction
due to damage or breakdown.
To avoid this, make preparations to install the machine as follows.
When the machine is scheduled to be transferred to another place, please contact the
marketing department or sales agency of Hitachi High-Technologies beforehand.
l
Select a place solid enough to support the mass of the machine.

please contact the marketing department or sales agency of Hitachi High-
Technologies for details.
l
Avoid any place that vibrates severely.
l
The ambient temperatures must be 20±10°C and humidity 30 to 80%. Any dew
condensation must be avoided.
When the machine is transferred to another place and the ambient temperature rises more
than the surface of the machine, dew may condense under the condition described below.
Note that dew condensation may cause the machine to break down.
Condition of Dew Condensation
Dew may condense when the dif
ference (based on "Humidity (%)") between the ambient
temperature of the destination (the place where the machine was transferred) and the
surface temperature of the machine reaches the values or more in the table below.
Humidity (%) of Destination
Differences between Ambient Temperature
of Destination and Surface Temperature of
Machine
80 3 °C or more
70 6 °C or more
60 8 °C or more
50 10 °C or more
40 14 °C or more
30 18 °C or more
l
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.

l
Do not expose the machine to combustible or corrosive gas.
l
Select a place free of lamp soot and dust.
l
Level the machine at the correct height, using a level vial
.
l
The machine should be free of obstacles around it for easy maintenance.
l
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 machines and the condition of
both machines.
Power Supply

Take necessary measures to prevent the other equipment from generating noises.

The primary power supply must be prepared on the local site.

•
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.

that it is a type of breaker that cancels the high-frequency element immediately after
the rated sensitivity current reaches 60 mA or higher.
•
GXH-1S Leakage Current: less than 30 mA
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.

Safety Precautions
Air Supply
Supply dry and clean air (Pressure: 0.45 to 0.69 MPa (4.6 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 hard disk data be periodically backed up with the
network terminal (option).
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les.
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.
