6.5 Power supply
• The power supply should meet the following requirement.
Voltage single phase 200V/220V/230V±10% or 240V±5%
Frequency 50Hz / 60Hz
Power 4kVA
• If the power source is shared with other electrical or electronic devices, the spark
discharge noise may cause them to malfunction. Therefore, if possible, provide an
independent power supply.
• Put a power switchboard between the power source and the instrument so that the
power can be turned off as needed.
6.6 Argon gas
• The argon gas should meet the following requirement.
Purity 99.999% or more
Oxygen concentration 1ppm or less
Dew point below -70°C
• 140 - 200kPa (1.4 - 2.0kgf / cm
2
) of pressure is required at PDA-7000 gas inlet.
If the argon gas is provided from a gas cylinder, a pressure regulator is needed.
(Ex.) Ar gas regulator P/N : 200-33871
Secondary pressure: 150kPa(1.5kgf / cm
2
)
• Plumbing pipes for high purity gases should be used. When the argon gas cylinder
is placed outdoors or 5m or more away from the instrument, use stainless steel
pipes.
• Attach a purge valve to the argon gas piping to clear out the air after the change of
gas cylinders.
• To prevent loss of pressure, thicker plumbing pipes are recommended.
• For the details of the plumbing, consult a plumber company.
6.7 Exhaust equipment
• Exhaust the oil mist from the vacuum pump to outdoors, or use oil mist separator.
(Ex.) Oil mist separator P/N 040-82714-31
Socket adapter FCMB1 P/N 035-42121
(needed to attach the oil mist separator to the
vacuum pump)
• Exhaust the argon gas emitted from the outlet of gas bubbler to outdoors using
exhaust systems.
