Panel Wiring

This section explains basic wiring procedures and precautions for I/O Modules.
It also explains grounding of Modules.
6.2.1

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) Wire these circuits so that are separated from each other as shown in the following fig-
ure.
