Power Supply

The B7AH is available in both normal-speed models and high-speed models. The recommended cable lengths and transmission distances are

different for the 2 types. If a single power supply is connected to the Input or Output Link Terminal, (i.e., on the input side or output side), there are

restrictions on the current that can flow along the power line.
