Use M3 terminal screws.
Connect a crimp connector with a ring terminal to each terminal screw.
Ring terminal
6.2 mm max.
!Caution Tighten the terminal block screws of the AC Power Supply to the torque of
0.5N S m. Loose screws may result in burning or malfunction.
| Use a DC power supply with sufficient capacity and low ripple. For a DC power |
| supply used for the transistor output, use a power supply with double insulation |
| or reinforced insulation to conform to the EC Directives |
| tives). The NC terminal is not used. |

!Caution Do not perform a withstand voltage test on a CPU Unit with a DC power supply. The test might damage the PC’s internal components.
Note 1. Do not conduct a withstand voltage test for the power supply section of the CPU Unit with a DC power supply. Doing so may damage internal elements.
2.Reinforced insulation or double insulation must be used for a DC power sup- ply to conform to the EC Directives (Low Voltage Directive).
Crimp Connectors
!Caution Always use crimp connectors for the CPM1A’s power lines and I/O lines or else use a solid wire (instead of a stranded wire). Do not connect bare stranded wires directly to terminals. Bare stranded wires connected directly to the terminal can cause a fire.
Use M3 terminal screws and tighten the screws securely (0.5 N S m).

6.2 mm max. | 6.2 mm max. |
The recommended wire size for solid wires is 0.4 to 1.2 mm (AWG26 to AWG18).
