Precautions
The cable is designed to connect with its key aligned with the keyway of the connector on the Vision Sensor. Do not force the
connections or damage may occur.
Connecting an I/O module to a power supply
Operating procedure
1.
Verify that the 24 V DC power supply being used is unplugged and not receiving power.
2.
Using a screwdriver, loosen the 24 V DC positive and negative terminals on the I/O module.
3.
Connect the 24 V DC power supply to the 24 V DC positive and negative terminals on the I/O module.
4.
Using a screwdriver, tighten the screws and fix the lead wires on the terminal block. The maximum tightening torque is
0.40 N⋅m.
Precautions
Do not connect the I/O modules to a power supply other than 24 V DC. Also, do not connect the 24 V DC power supply to any
terminal other than the 24 V DC positive and negative terminals. Failure to do so may result in fire or failure.
Connecting an I/O module to a frame ground
Operating procedure
1.
Connect the frame ground wire to the frame ground terminal of the I/O module.
2.
Connect the other end of the frame ground wire to the frame ground.
Precautions
The frame ground terminal and the shield ground of each connector (SENSOR port and RS232 OUT port) are contacted in
the I/O module.
The system ground is designed on the condition that a ground connection is provided.
The ground potential may affect the vision sensor and peripheral devices such as programmable controllers via cables.
For safe operation, connect all the ground connections securely.
