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.
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.
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.
