Important
1. External Power Source
In the case of supplying the following terminals with an external power source,
use a DC power supply with the safety extra-low voltage output.
• COM IN terminals of Terminal Block Units or Parallel I/O Units
• COM OUT terminals of Terminal Block Units or Parallel I/O Units
• COM terminals of Power Supply Units
2. Location
Do not install an F300 System in locations subject the following conditions:
• Temperatures outside 0°C to 50°C
• Condensation due to rapid temperature fluctuations
• Relative humidity outside 35% to 85% RH
• Corrosive or flammable gas
• High concentrations of dust, salt, or iron particles
• Direct vibration or shock
• Direct sunlight
• Water, oil, or chemicals fumes or spray
3. Installation
• Temperature Considerations:
Consider environmental factors and ease of operation and maintenance when
installing the F300 System in a control box.
The operational temperature range of the F300 System is 0°C to 50°C. Take
the following measures to maintain the F300 System in this range.
• Maintain a minimum of 50-mm clearance above and below the F300 Sys-
tem to improve air flow.
• Do not install the F300 System immediately above strong heat sources,
such as heaters, transformers, or large-capacity resistors.
• Provide a forced-air fan or air conditioning if the ambient temperature
exceeds 50°C.
• Operation and Maintenance Considerations:
Keep the F300 System away from high-voltage equipment and motors to
improve safety during operation and maintenance.
