5.3.1 Separation of Power Supply Systems
1) The power supply circuits for the GL120 and GL130 can be divided into the following four
systems:
a) Power supply for the Power Supply Module
b) Power supply for I/O circuits
c) Power supply for operation circuits
d) Power supply for main circuits
2) Please wire these circuits independently from each other as shown in the figure below:

5.3.2 Wiring the Power Supply Module
Connect the power supply cable and ground cable to the Power Supply Module. Connecting
the power supply cable to the Power Supply Module is described in this section. Connecting
the ground cable is described in item 2. Grounding the Power Supply Module under 5.3.5
