Note 1. The transmission distance depends on the type of wiring used.
2. The size of terminal screw differs for the B7A Interface Unit and B7A Link
Terminal. Consider the size of the terminal screws when using crimped ter-
minals.
3. It is recommend that the shield wire be grounded.
4. If shielded cable is not used, the transmission distance is not to exceed 10 m
regardless of whether power supply is common or wired separately (using
VCTF 0.75 mm
5. Locate transmission cables away from power cables and high-voltage
cables to eliminate the effects of noise.
