Chapter 4 Power Wiring, Power Consumption Calculation, and Power Sequence Requirements
The schematic diagram of power module is shown below. Also be cautious about the following:
1. Please follow the wiring schemes regulated by local national standards to use single-pole switch
（break hot wire〝L〞 ）, or double-pole switch（break both〝L〞and〝N〞 ）, to turn on or off the
AC input power.
2. In wiring, hot wire〝L〞must be connected to the L terminal on unit, while the ground line〝N〞
connected to the N terminal. Please use wires with diameters 1mm
3. All terminals on CPU module or Power module have to be connected to the EG (Earth
Ground) terminal of main power system as shown in the figure below, with wire diameters larger
than 2mm .

Output of 24VDC power for input circuit cannot be connected in parallel with other powers, in which
the conflict between two sets of power will decrease their lifetime or cause immediate damage. This
will induce unexpected malfunction of PLC and cause serious or even deadly damage to people or
equipment.
