6 Installation
Before installing PDA-7000, carefully prepare the location of the installation and the
configuration of the peripheral equipment by referring the following guidelines.
6.1 Temperature and humidity
• The installation site should be air-conditioned and meet the following conditions.
Temperature 10 - 28°C (variations within ±5°C / hour)
Humidity 15% - 70%RH (no condensation)
• Instruments should not be exposed to direct sunlight.
• PDA-7000 system generates about 1,100kcal / hour of heat.
To estimate the total heat release, the heat generated by operators and the room
light also should be considered.
6.2 Vibration
• The installation site should meet the following conditions.
Acceleration less than 0.2G
Amplitude less than 80µm
Velocity less than 0.8cm / sec
6.3 Dust
PDA-7000 uses high voltages and tiny electrical currents. Therefore, dust can cause
it to malfunction. The installation site should be as free as possible of dust.
To prevent dust, implement dust-prevention measures in the doors and windows of
the room where the system is installed.
6.4 Grounding
• If the grounding is shared with other electrical or electronic devices, the spark
discharge noise may cause them to malfunction. Therefore, provide an independent
grounding.
• The grounding condition should meet the following requirement.
Grounding resistance less than 30Ω, independent grounding
(if possible, less than 10Ω, independent grounding is
highly recommended)
• If the distance between the instrument and ground point is too far, it will increase
the chance of generating the noise. Therefore, keep the length of the grounding
wire as short as possible. Also, the grounding wire should be as thick as 8mm
2
(AWG#8) or more. (14mm
2
(AWG#6) or more is recommended.)
