The B7A Interface Unit can be connected to the input and output B7A Link Termi-
nals using the following cables.
Use a VCTF 0.75 x 3 C cabtire cable (100 m max.) if a power supply is shared
and a VCTF 0.75 x 2 C cabtire cable (500 m max.) if power is supplied indepen-
dently.
Use a 0.75 x 3 C shielded cable (50 m max.) if a power supply is shared and a
0.75 x 2 C shielded cable (100 m max.) if power is supplied independently.
If shielded cable is not used for the high-speed transmission delay-time Link Ter-
minal, the transmission distance is not to exceed 10 m regardless of whether
power supply is shared or wired separately.
Connect the input and output B7A Link Terminals to the B7A Interface Unit via
the following terminals using crimp-style terminals used for CQM1H/CQM1 I/O
Units.
