*1 If the XW2Z-200T-4 Cable is used with the NV3W(-V1), 5 V can be sup-
plied from the PLC instead of from an external power supply.
In that case, the power consumption or current consumption shown in the
above table will be provided from the PLC power supply, so be sure to cal-
culate the entire 5-V current consumption at the PLC and to stay within
that range.

Wiring Procedure
Use the following procedure to connect the power supply.
1. Strip the power supply cable.
7 mm
2. Remove the communications/power connector from the PT.
(NV3Q only)
3. Insert the wire into the terminal block until it stops, and secure it by tight-
ening the screw clockwise.
Using a small flat-blade screwdriver, tighten the screws to a torque of 0.22
to 0.3 N·m.
4. Attach the communications/power connector to the PT.
Observe the following points to avoid disconnections.
• Be careful not to cut the wire when stripping off the sheath.
• Connect the conductor without twisting the wires.
• Connect the conductor without soldering the wires. Wires can become
disconnected due to vibration.
• Do not apply stress to the cable after the wires have been connected.
