customer needs to prepare.
- This diagram shows cases for motors with standard Japanese domestic specifications. Please consult with us for motors with overseas
specifications.
- When using inverter for 400v class 3-phase motor / high-efficiency 3-phase motor, the motor must be insulated.
For AF motor for inverter with axial flow fan (fully enclosed ventilation type) , note the following points.
- Connect electric power to an axial fan as well.
- In the case of 400 V class indoor equipment, the power source voltage for the axial fan is 200 V. In the case of special specifications, the
actual product may sometimes differ from the above drawing, so check the manufacturing specifications.
- Connect the fan so that it rotates in the direction indicated on the nameplate.
(When the fan is operating normally, it should blow cooling air from the non-load side to the load side.)
- When leaving the motor stopped for a long period, leave the axial fan motor stopped as well.
- As thermostat is installed to the motor, wiring to it.
