6-1 Installing Units
This section describes how to mount Units to an EtherCAT Slave Terminal.
To increase the reliability of the EtherCAT Slave Terminal and take complete advantage of its function-
ality, observe the following precautions.
Do not install the EtherCAT Slave Terminal in the following locations.
• Locations subject to ambient temperatures outside the range of 0 to 55°C
• Locations subject to condensation as the result of severe changes in temperature
• Locations subject to a relative humidity outside the range of 10% to 95%
• Locations subject to corrosive or flammable gases
• Locations subject to excessive dust, salt, and metal powder
• Locations subject to shock or vibration
• Locations subject to direct sunlight
• Locations subject to splashing of water, oils, or chemicals
Take appropriate and sufficient countermeasures when installing the EtherCAT Slave Terminal in the
following locations.
• Locations subject to static electricity or other forms of noise
• Locations subject to strong electromagnetic fields
• Locations subject to possible exposure to radioactivity
• Locations close to power lines
Consider the ambient temperature, accessibility for operation, accessibility for maintenance, noise
immunity, and installation orientation when you install the EtherCAT Slave Terminal in a cabinet or con-
trol panel.
Temperature Control
The ambient operating temperature of the EtherCAT Slave Terminal must be between 0 and 55°C.
When necessary, take the following steps to maintain the proper temperature.
• Provide enough space for good air flow.
• Do not install the EtherCAT Slave Terminal directly above equipment that generates a large
amount of heat such as heaters, transformers, or high-capacity resistors.
• If the ambient temperature exceeds 55°C, install a cooling fan or air conditioner.
