The followings explains the wiring instructions for use of the system.
10.2.1 Power Supply Wiring
1) When voltage fluctuations are larger than the specified value, connect a constant-voltage transformer.
2) Use a power supply which generates minimal noise across wire and across PLC and
ground. (When excessive noise is generated, connect an insulating transformer)
3) When wiring, separate the PLC power supply from the I/O and power device as shown
below.
