Connecting the Cable
Precautions for Correct Use
• Turn OFF the Controller's power supply before connecting or disconnecting Ethernet commu-
nications cable.
•
Allow extra space for the bending radius of the communications cable.
For the CPU Unit dimensions when the communications cable is connected to the Unit, refer
to the NJ-series CPU Unit Hardware User's Manual (Cat. No. W500), NX-series CPU Unit
Hardware User’s Manual (Cat. No. W535), NX-series NX102 CPU Unit Hardware User’s
Manual (Cat. No. W593), or NX-series NX1P2 CPU Unit Hardware User's Manual (Cat. No.
W578). The required space depends on the communications cable and connector that are
used. Consult the manufacturer or sales agent.
