Wiring between the B7A Interface Unit, input B7A Link Terminal, and output B7A
Link Terminal sharing a single power supply differs from wiring between Units
using independent power supplies as shown in the following diagrams.
Transmission distance: 100 m max.

Transmission cable: VCTF 0.75 mm
Transmission distance: 500 m max.

Transmission cable: VCTF 0.75 mm
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. Locate transmission cables away from power cables and high-voltage
cables to eliminate the effects of noise.
