9   LOADING AND INSTALLATION 

 

9.5 Connection and Disconnection of Extension Cable 

(1)   Instructions for handling an extension cable 

• Do not stamp an extension cable. 

• An extension cable must be connected to the base unit when the base cover 

has been installed. 

(After you have set the extension number to the extension base unit, reinstall 

and screw the base cover.) 

• When running an extension cable, the minimum bending radius of the cable 

should be 55mm (2.17 inch) or more. 

If it is less than 55mm (2.17 inch), a malfunction may occur due to characteristic 

deterioration, open cable or the like. 

• When connecting or disconnecting an extension cable, do not hold the ferrite 

cores mounted at both ends of the cable. 

Hold the connector part of the cable for connection or disconnection. 

 

Holding the ferrite core may cause the cable to open within the connector. 

Also, if the ferrite core is shifted, the characteristic will change. When handling 

the cable, take care not to shift the ferrite core positions. 

 

(2)   Connection of extension cable 

 

POINT 

 

When connecting an extension base unit to the main base unit with an extension 

cable, always plug the OUT side connector of the main base unit and the IN side 

connector of the extension base unit with an extension cable. The system will not 

operate properly if the extension cable is connected in the form of IN to IN, OUT to 

OUT or IN to OUT. 

When connecting two or more extension base units, plug the OUT side connector 

of the first extension base unit and the IN side connector of the second extension 

base unit with an extension cable.
