Connection of End Unit
If the cable lengths are the same, connect the end unit to the line having fewer nodes.
CAUTION
Be sure to connect one SL-VEU end unit to the end of the main line.
If the branch line length exceeds 80% of the maximum transmission distance, connect one SL-VEU unit to the
end of the branch line, too.
<If the branch line length is equal to the main line length>
Same length (Note 1)
Connect the end unit to the
line having fewer nodes.
SL-VEU
<If the branch line length is 80% of the main line length or more>
80% of main line length or more
Maximum transmission distance
Main line
Connect the end unit to the main line
and branch line, respectively.
SL-VEU
Notes: 1) Even if the cable lengths are the same, if both the main and branch line lengths exceed 80% of the maximum transmis-
sion distance, connect two SL-VEU end units. Note that it is not possible to connect more than two SL-VEU end units.
2) The maximum transmission distance depends on the cable conductor cross section and the number of nodes.
