•
Overvoltage Category : Category
III
•
Pollution Degree : 3
•
Altitude : 1,000 m or less above the sea level
Overvoltage Categories refer to the level of Impulse Withstand Voltage protection
provided at the specied Pollution Degree.
Category III
:
Primary circuits of a device to which power is directly
supplied from the power distribution panel, and circuits from
the distribution panel to outlets.
Note
The term was changed from "Installation Category" to "Overvoltage
Category".
"Pollution Degree" is a degree of pollution severity.
Pollution Degree 3 : Conductive pollution or dry nonconductive pollution that
becomes conductive due to condensation occurs.
To be found in industrial environment or construction sites
(harsh environments).
Altitude means the height above sea level of the place where the machine is to be used.
Note
When the machine is used in a place that has an altitude of 1,000 meters
or more, consult with the Marketing Dept of Hitachi High Technologies
or a sales agent.

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.
Select a place solid enough to support the mass of the machine.
Note
It is recommended that the machine should be installed on the rst oor.
When the machine has to be installed on a oor other than the rst one, please
contact the marketing department or sales agency of Hitachi High-Technologies
for details.
Avoid any place that vibrates severely.
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 difference (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

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.
Power Supply
Conrm that the following power is supplied to the main machine (SIGMA-G4/G5).
•
Voltage : 200 ± 20 V AC, 3-Phase
•
Apparent Power
: Approx. 6.7 kVA
Fluctuating voltage and noise in the power line can have not only a bad inuence 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.
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 main machine (SIGMA-G4/G5).
When the supplied air contains much moisture, etc., the machine may not work normally
due to the moisture, etc., accumulated in the machine.
