Observe the following points.
• The coils and contacts in electromagnetic contactors and relays in an external circuit are sources of
noise. Do not install them close to the EtherCAT Slave Terminal. Locate them at least 100 mm away
from the EtherCAT Slave Terminal.
Observe the following points when wiring the power supply system.
• Separate the EtherCAT Slave Terminal power supply from the I/O device power supply and install a
noise filter near the power supply feed section.
• Use an isolating transformer to significantly reduce noise between the EtherCAT Slave Terminal and
the ground. Install the isolating transformer between a power supply and the noise filter, and do not
ground the secondary coil of the transformer.
• Keep the wiring between the transformer and the EtherCAT Slave Terminal as short as possible, twist
the wires well, and keep the wiring separate from high-voltage and power lines.
