This section describes the precautions to be taken for wiring.
Power wiring
1. You must use 24V DC power supply.
−
If the power variation is more than the regular range, you must connect a
constant voltage transformer.
−
To prevent noise from the power cable, twist the power cable as densely as
possible and connect within the shortest distance.
−
Provide the power where the noise is lesser. (If there is much noise, connect the
Isolation transformer.)
−
For PLC, I/O machine and power machine, it is required to divide the power as
follows.
Where T1, T2: Constant voltage transformer.
−
Use 2mm² thick power cable to reduce the voltage fluctuation.
