NX-series EtherCAT Coupler Unit User’s Manual (W519)
• 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.
• Do not incline or twist the flat-blade screwdriver while it is in a release hole on a screwless clamping
terminal block. Doing so may damage the terminal block.
• Use all Units within the I/O power supply ranges that are given in the specifications.
• Supply sufficient power according to the contents of this manual.
• Use the power supply voltage that is specified in this manual.
• Do not apply voltages that exceed the rated value to any Input Unit.
• Do not apply voltages or connect loads to the Output Units or slaves in excess of the maximum rat-
ings.
• Inrush current occurs when the power supply is turned ON. When selecting fuses or breakers for
external circuits, consider their fusing and detection characteristics as well as the above precautions
and allow sufficient margin in shut-off performance.
• Install external breakers and take other safety measures against short-circuiting and overcurrents in
external wiring.
• When you set the Operating Mode at Startup, confirm that no adverse effect will occur in the system.
• Before you start operation, always register the NX Units that are connected to the Communications
Coupler Unit in the host communications master as the Unit Configuration Information.
