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