Caution Do not perform a dielectric test on a DC-type CPU Unit. Use the Power Supply
provided with double insulation or reinforced insulation for conforming to the EC
Directives (Low-voltage Directives).
3-4-3 Input Wiring
Wire the inputs to the CPM1’s CPU Unit and Expansion I/O Unit as shown in the
following diagrams. Use crimp connectors or single-wire lines (not stranded
wire) to connect to the PC. The power supply output terminals can be used with
AC-type CPU Units.
CPM1-10CDR- CPU Units An AC-type CPU Unit is shown. DC-type CPU Units don’t have power supply
outputs.
