Precautions for Safe Use
Power Supply and Wiring
• Make sure to use the product with the power supply voltage specified by the user manual.
• Do not connect Code Reader to AC power. Applying AC power will cause the unit to fail.
• Use a wire size suitable to the current consumption and length of wire.
• Use a DC power supply with safety measures against high-voltage spikes (safety extra low-voltage
circuits on the secondary side). If the system must meet UL standards, use a UL Class 2 power supply.
• Confirm that the following conditions are met before applying power to the reader:
• Correct voltage and polarity;
• Proper load and output wiring;
• All wiring is correct for the application.
Ground
• Ensure that the power supply circuit of the unit is insulated from the internal circuit. Refer to the user manual.
• Check wiring again before turning on the unit.
Other
• Use only the cables designed specifically for the product. Use of other products may result in
malfunction of, or damage to, the product.
• Always turn OFF the power of the reader and peripheral devices before connecting or disconnecting a
cable. Connecting the cable with power supply on may result in damage to the reader or peripheral devices.
• Do not apply torsion stress to the cable. It may damage the cable.
• Secure the minimum bending radius of the cable. Otherwise the cable may be damaged.
• Do not attempt to dismantle, repair, or modify the product.
• Should you notice any abnormalities, immediately stop use, turn OFF the power supply, and contact
your OMRON representative.
• While the power is ON or immediately after the power is turned OFF, the case is still hot. Do not touch
the case.
• When disposing of the product, treat it as industrial waste.
• Do not drop the product or apply excessive vibration or shock to the product. Doing so may cause
