Note
The items under this heading contain important handling instructions that the user should observe to ensure safe use of the product.
Warning
General
• Do not use the product in explosive or corrosive environments, in the presence of flammable gases, locations subjected to
splashing water, or near combustibles. Doing so may result in fire, electric shock or injury.
• Assign qualified personnel the task of installing, wiring, operating/controlling, inspecting and troubleshooting the product.
Failure to do so may result in fire, electric shock or injury.
• 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.
• Turn off the power in the event the overheat protection device (thermal protector) is triggered. Failure to do so may result in
injury or damage to equipment, since the fan will start abruptly when the overheat protection device (thermal protector) is
automatically reset.
Installation
• To prevent the risk of electric shock, use the motor for class equipment only.
• Install the motor in an enclosure in order to prevent electric shock or injury.
• Install the motor and control unit so as to avoid contact with hands, or ground it to prevent the risk of electric shock.
Connection
• Keep the control unit’s input-power voltage within the specification to avoid fire and electric shock.
• Connect the cables securely according to the wiring diagram in order to prevent fire and electric shock.
• Do not forcibly bend, pull or pinch the cable. Doing so may fire and electric shock.
• To prevent electric shock, be sure to install the terminal cover over the control unit’s terminals after making connections.
• Do not remove the covers attached to the 60 W-type and 90 W-type capacitors.
• The control unit is not equipped with overcurrent protection. Install a device for overcurrent protection (e.g. circuit breaker)
before connecting the unit to the power source. Failure to do so may result in fire.
Operation
• Turn off the control unit power in the event of a power failure, or the motor may suddenly start when the power is restored and
may cause injury or damage to equipment.
Maintenance and inspection
• Do not touch the connection terminals of the control unit and capacitor immediately after the power is turned off (for a period of
10 seconds). The residual voltage may cause electric shock.
Repair, disassembly and modification
• Do not disassemble or modify the motor or control unit. This may cause electric shock or injury. Refer all such internal
inspections and repairs to the branch or sales office from which you purchased the product.
