Basic Procedures
Extension of Main / Branch Line Cable
●
If you do not use the exclusive 4-core flat cable, be sure to use the 4-core VCTF cable (non-
shielded) having 0.3 to 2.0mm
2
conductor cross section. In addition, if you connect cables of dif-
ferent types to each other, be sure to select cables having the same cross section. If you connect
cables having different cross sections to each other, abnormal communication signals may be out-
put, and abnormal operation of the system may be caused.
●
The cables commercially available have different performances.
Before using these cables, be sure to check operation.
CAUTION
Note: The VCTF cord is the vinyl cabtyre cord that conforms to the requirements of JIS C 3306 ‘Polyvinyl chloride insulated flexible cords.’
Extension of exclusive 4-core flat cables
Hook-up the cables using the
SL-J3A
hook-up connector for cable extension to extend the cable.
(For a detailed description of the hook-up method, refer to pages 37, 38 and 41 to 43.)
Extension of cable excluding exclusive 4-core flat cables
Use a connector or junction terminal block commercially available to extend the cable.
Extension of cable to I/O device
Use the snap male connector (
SL-CP1
,
SL-CP2
, or
SL-CP3
) and the snap female connector (
SL-CJ1
