NX-series PROFINET Coupler Unit User’s Manual (W623)
This section describes how to mount NX Units to the PROFINET 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 Profinet
IO Device Terminal.
Precautions for Correct Use
• When you mount an NX Unit to the PROFINET Coupler Unit or when you connect NX Units
to each other, always mount the Units one at a time on the DIN Track. If you connect NX
Units to each other and attempt to mount them together to the DIN Track at the same time,
the Units may separate from each other and fall.
• When you handle a Unit, be careful not to apply stress to the pins in the NX bus connector.
If the Unit is installed and the power supply is turned ON when the pins in the NX bus con-
nector are deformed, contact failure may cause malfunctions.
• When you handle a Unit, be careful not to touch or bump the pins in the NX bus connector.
