WARNING
Never connect the AC power supply with this product. When the AC power supply is con-
nected, it causes the electric shock and a fire.
Do not touch the terminals while the power supply is ON. Doing so may result in electrical
shock.
Caution
Please take fail-safe measures on your side in preparation for an abnormal signal due to sig-
nal conductor disconnection and/or momentary power interruption. An abnormal operation
may result in a serious accident.
Precautions for Safe Use
• Check the following again before turning on the power.
- Are the voltage and polarity of the power source set correctly? (24 VDC for positive termi-
nal. 0 VDC for negative terminal.)
- Is the FG (functional grounding terminal) connected to the ground?
- Is the load of the output signal not short-circuited?
- Is the load current for the output signal within the specified range?
- Are there no wrong wirings?
• While the power is ON or immediately after the power is turned OFF, the Sensor Controller
and camera case are still hot. Do not touch the case.
• Make sure to turn off the power when attach or detach cameras or cables. Connecting cables
while the power is supplied may cause malfunction or damage to cameras or peripheral devi-
ces.
• Illumination is normal immediately after the power supply is turned ON. Do not look directly
into the illumination light.
• After confirming that the product is started up, communicate with the high-order device.
• Should you notice any abnormalities, immediately stop use, turn OFF the power supply, and
contact your OMRON representative.
