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 dimensions when the communications cable is connected to the Unit, refer to Installa-
tion Height
on page A-3. The required space depends on the communications cable and
connector that are used. Consult the manufacturer or sales agent.
