Precautions for Safe Use
NX-series PROFINET Coupler Unit User’s Manual (W623)
• Do not write on the Communications Coupler Unit or 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 malfunc-
tions in the IO Device Terminal.
• For the installation orientations in the following figure, support the cables, e.g., with a duct, so that
the End Plate on the bottom is not subjected to the weight of the cables. The weight of the cables
may cause the bottom End Plate to slide downward so that the IO Device Terminal is no longer
secured to the DIN Track, which may result in malfunctions.
• Double-check all switches and other settings and double-check all wiring to make sure that they are
correct before turning ON the power supply.
Use the correct wiring parts and tools when you wire the system.
• Do not pull on the cables or bend the cables beyond their natural limit. Also, do not place heavy
objects on top of the cables or other wiring lines. Doing so may break the cable.
• When wiring or installing the Units, do not allow metal fragments to enter the Units.
• Do not press the flat-blade screwdriver straight into the release holes on a screwless clamping termi-
nal block. Doing so may damage the terminal block.
• When you insert a flat-blade screwdriver into a release hole on a screwless clamping terminal block,
press it down with a force of 30N or less. Applying excessive force may damage the terminal block.
