Precautions for Wiring the EtherCAT Slave Terminal Together
with Computers and other Peripheral Devices
Caution
When you connect a computer or other peripheral device to the following Unit, either ground the 0-V
side of the external power supply (i.e. Unit power supply) or do not ground it at all.
• EtherCAT Coupler Unit with a non-isolated DC power supply (internal power supply cir-
cuits)
Depending on how the peripheral device is grounded, the external power supply (i.e. Unit power sup-
ply) may be shorted. Never ground the 24-V side of the power supply, as shown in the following fig-
ure.
