Incorrect wiring patterns
a) Do not mix different types of cabling when connecting modules.
Do not leave any terminals unconnected as shown below.
b) Do not create loops.
Power distribution
a) Distributing power to each module from individual power supplies (A common
power supply is not required.)
b) Distributing power to all modules from one power supply
Note: The long communication cable used in the above power distribution pattern is
subject to voltage drop. In such a case, use a cable of sufficient thickness.
