Connecting the Power Supply and
Ground Wires
This section describes how to wire the power supplies and ground the EtherCAT Slave Terminal.
The wiring of the power supply and ground to the EtherCAT Coupler Unit is shown in the following fig-
ure.
Unit Power Supply Terminals
These terminals are connected to the Unit power supply. The details are given in the following table.
You can use the unwired terminals for through-wiring to an Additional NX Unit Power Supply Unit or
to the Unit power supply terminals on another EtherCAT Coupler Unit. Make the current supplied
from the unwired terminals meet the following conditions.
Current supplied from unwired terminals = Current capacity of power supply terminals
−
Current
consumption of the EtherCAT Coupler Unit block
Refer to
5-4-1 Selecting the Unit Power Supply
on page 5-15 for details on blocks.
I/O Power Supply Terminals
These terminals are connected to the I/O power supply. The details are given in the following table.
Provide a power supply voltage that is within the power supply voltage specifications of the NX Unit
I/O circuits and connected external devices.
