Chapter 7 Wiring
7-1 Cable trunk and branch lines
① On the illustration of the cable wiring below, a bold line means a trunk and the thin lines branched
from the trunk with a "T" shape are called branch lines.
② The length of branch lines branched from the trunk should be within 400 mm.
③ Total cable length should be within 1 km.
7-2 Relaying of trunk cables
① To relay trunk cables, use the straight joint (ME-JJ-01).
② Relaying of trunk cables should be limited to indispensable cases only. Inadvertent relaying of
trunk cables may cause a communication fault such as a weakened signal level due to contact
resistance in the junction connector (straight).
