3. Insert the pin terminals into the CompoBus/S terminal block on the
CPM2B-S CPU Board and tighten the locking screw.
The CompoBus/S Terminal specifications are as follows:
Tighten the terminal set screws to a torque of 0.2 to 0.4 N•m.
Note Before inserting the signal wires, loosen the terminal set screws sufficiently. If
the set screws aren't loosened, it won't be possible to insert the wires fully
and the wires won't be secured in the terminals.
The maximum lengths of the trunk line, branch lines, and total transmission
line length depend on the communications mode and the kind of transmission
line (flat cable or VCTF cable) being used. The maximum lengths are further
restricted if flat cable is being used with more than 16 Slaves.
