Additional Information
It is not normally necessary to unlock the DIN Track mounting hooks when you mount the
EtherCAT Coupler Unit. However, if you mount the EtherCAT Coupler Unit on a DIN Track that
is not one of the recommended DIN Tracks, the DIN Track mounting hooks may not lock prop-
erly. If that happens, unlock the DIN Track mounting hooks at the start of the procedure, mount
the Unit to the DIN Track, and then lock the DIN Track mounting hooks.

Installing and Connecting NX Units

This section describes how to mount NX Units to the EtherCAT Coupler Unit and how to connect NX
Units to each other.
Precautions for Safe Use
• Always turn OFF the power supply before mounting the NX Units. If the power supply is not
OFF, the Unit may malfunction or may be damaged.
• Do not apply labels or tape to the Units. When the Units are installed or removed, adhesive or
scraps may adhere to the pins in the NX bus connector, which may result in malfunctions.
• Do not write on an NX Unit with ink within the restricted region that is shown in the following
figure. Also do not get this area dirty. When the Unit is installed or removed, ink or dirt may
adhere to the pins in the NX bus connector, which may result in malfunctions in the EtherCAT
Slave Terminal.
