Functional Ground Terminals
These are the functional ground terminals. Connect the ground wire to one of these terminals. The
details are given in the following table.
Precautions for Correct Use
Do not connect the through-wiring terminals on the Unit power supply terminals to the I/O
power supply terminals. Always use separate power supplies for the Unit power supply and the
I/O power supply. Otherwise, noise may cause malfunctions.
7-2-5 Wiring to the Screwless Clamping Terminal Block
on page 7-14 for the procedure to
connect wires to the terminals on the screwless clamping terminal block.
Refer to
Section 5 Designing the Power Supply System
for information on wiring the power supplies to
the EtherCAT Slave Terminal.
This section describes how to ground the EtherCAT Slave Terminal.
Some of the Units in an EtherCAT Slave Terminal have ground terminals.
Units with Ground Terminals
• EtherCAT Coupler Units
• Additional NX Unit Power Supply Unit
• Shield Connection Unit
When connecting NX Units to external devices, the Shield Connection Unit is used to connect
the shield wire when the shield is used. You can ground more than one shield wire to the same
ground pole to reduce the amount of wiring work for grounding. For the specifications of the
Shield Connection Unit, refer to the
NX-series System Units User’s Manual
(Cat. No. W523).
Type of Ground Terminals
The ground terminals are functional ground terminals.
Functional grounding is done to protect device and system functions, including prevention of noise
from external sources, or prevention of noise from devices or equipment that could have harmful
effects on other devices or equipment.
