1.
Align the power supply connector with the socket on the bottom of the
CPM2C-S and insert the connector.
2.
To remove the power supply connector, grasp the power supply connector
(not the wires), release the lock tab on the connector, and remove the con-
nector.
Note
1.
The CPM2C-PA201 is the recommended Power Supply Unit, but a gener-
al-purpose power supply such as a S82J-series or S82K-series Power
Supply can also be used. When using other power supplies, be sure to use
a DC power supply with sufficient capacity and low ripple.
2.
Do not perform a voltage withstand test on the DC power supply terminals
on the CPU Unit. The test might damage the PC’s internal components.
3.
When the equipment must conform to the EC Directives (Low-voltage Di-
rectives), use a power supply with double insulation or reinforced insula-
tion.
3-4-3
Using the AC Power Supply Unit
Crimp Terminals
Use round crimp terminals for wiring AC power supply to the AC Power Sup-
ply Unit (CPM2C-PA201). Use either crimp terminals or solid wires for wiring
to the ground terminal or the service power supply terminals. Do not connect
bare stranded wires directly to terminals.
• Use M3.5 terminal screws.
• Tighten the terminal screws securely to a torque of 0.74 to 0.9 N·m.
Use round terminals of the dimensions shown below.
Recommended wire diameter when using solid wires: 0.6 to 1.6 mm (AWG 22
to 14).
Grounding
To prevent electric shock resulting from malfunction due to factors such as
noise, connect to a ground of 100
Ω
or less. When grounding, use a wire at
least 1.25 mm
2
thick.
Red lead: +24 VDC
Black lead: 0 VDC
Round Terminal
6.2 mm max.
