Handling the product without observing the instructions that accompany a “Caution” symbol
may result in injury or property damage.
The items under this heading contain important handling instructions that the user should
observe to ensure safe use of the product.
General
•
Do not use the product in explosive or corrosive environments, in the presence of ammable gases or near
combustibles. Doing so may result in re, electric shock or injury.
•
Only qualied and educated personnel should be allowed to perform installation, connection, operation and
inspection/troubleshooting of the product. Handling by unqualied and uneducated personnel may result in re,
electric shock, injury or equipment damage.
•
Do not transport, install the product, perform connections or inspections when the power is on. Always turn the
power off before carrying out these operations. Failure to do so may result in electric shock or equipment damage.
•
The terminals on the driver marked with
symbol indicate the presence of high voltage. Do not touch these
terminals while the power is on. Doing so may result in re or electric shock.
•
Do not use a motor in a vertical application. If the driver’s protection function is activated, the motor will stop and
the moving part of the equipment will drop, thereby causing injury or equipment damage.
•
If the driver protective function was activated, remove the cause and reset the protective function. Continuing the
operation without removing the cause of the problem may result in malfunction of the motor and driver, leading to
injury or damage to equipment.
Installation
•
The motor and driver are Class I equipment. When installing the motor and driver, connect their Protective Earth
Terminals. Failure to do so may result in electric shock.
Connection
•
Securely connect and ground in accordance with the connection diagram. Failure to do so may result in re or
electric shock.
•
Do not forcibly bend, pull or pinch the cables. Doing so may result in re or electric shock.
•
Do not machine or modify the motor cable or the connection cable. Doing so may result in electric shock or re.
•
Do not apply any excessive force to the motor connector for the connector type. Doing so may result in electric
shock or re.
•
Do not remove the connector cap for the connector type until the connection cable is connected so that the O-ring
of the connector connection on the motor is not damaged. Doing so may result in electric shock or re.
•
Be sure to observe the specied cable sizes. Use of unspecied cable sizes may result in re.
Operation
•
Use a motor, gearhead, and driver only in the specied combination. An incorrect combination may cause in re,
electric shock or equipment damage.
•
Keep the input power voltage of the driver within the specied range. Failure to do so may result in re or electric shock.
Maintenance and inspection
•
Always turn off the power before performing maintenance/inspection. Failure to do so may result in electric shock.
•
Do not touch the motor or driver when conducting insulation resistance measurement or dielectric strength test.
Accidental contact may result in electric shock.
•
Do not touch the connection terminals on the driver immediately (within 1 minute) after the power is turned off.
Residual voltage may cause electric shock.
•
Regularly check the openings in the driver for accumulated dust. Accumulated dust may cause re.
Repair, disassembly and modication
•
Do not disassemble or modify the motor, gearhead, and driver. Doing so may result in electric shock, injury or
equipment damage. Should you require inspection or repair of internal parts, please contact the Oriental Motor
