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 first floor.
When the machine has to be installed on a floor other than the first 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.
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. 11.5 kVA
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 fi
rst 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.
