GX-series EtherCAT Slave Unit User’s Manual
Precautions for Correct Use
• Wire all connections correctly according to instructions in this manual.
Failure to install them may result in serious accidents.
• Do not operate the control system in the following locations:
• Location subject to direct sunlight.
• Locations subject to temperatures or humidity outside the range specified in the specifications.
• Locations subject to condensation as the result of severe changes in temperature.
• Location subject to corrosive or flammable gases.
• Location subject to dust (especially iron dust) or salts.
• Location subject to exposure to water, acid, oil, chemicals, etc. (General-purpose Slaves)
• Location subject to exposure to acid, oil, chemicals, etc. (Environment-resistive Slaves)
• Locations subject to shock or vibration.
• Locations close to power lines.
• Confirm voltage specifications when wiring communications, the power supply, and I/O crossovers.
Incorrect wire may result in malfunction.
• Wire all connections correctly according to instructions in this manual.
• Use the correct wiring materials to wire the Unit.
• Take appropriate and sufficient countermeasures when installing systems 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 supplies.
• Do not drop any Unit or subject any Unit to excessive shock or vibration. Otherwise, Unit failure or
malfunction may occur.
• When you attach the switch cover, make sure that the packing is not twisted. Also confirm that there
is no foreign matter adhering to the case and packing.
• Do not use the Unit continuously submerged in water.
• Do not disconnect the EtherCAT communications cables during operation. The outputs will become
unstable. However, for the built-in EtherCAT port on the NJ/NX-series CPU Unit, it is OK to discon-
nect the communications cable from an EtherCAT Slave Terminal that has been disconnected from
communications in the software.
