Note the following for forced ventilation types
•
•
Insulation suitable for a motor is necessary in inverter drive with 3-phase 400V motor or 3-phase 400V high
efficiency motor.
• Connect power source for forced ventilation fan.
• For an indoor 400V class, the axial fan power source voltage will be 200V class. For special specifications,
specifications may differ from the above. Check the manufacturing specifications.
• Wire so that the fan rotation direction is relevant with "rotation direction nameplate" when 3-phase motor is used for
forced ventilation fan.
(Wind should blow from the unconnected side to the connected side of the drive.)
• When you stop a motor for a long time, a forced ventilation fan should also stop.
• Wire the thermostat.
• Specification for thermostat
Terminal symbol : T1 & T2 or P1 & P1
Operating temperature : 135 C(Thermal class 155(F))
Operating function : Normal closed(contact point b)
Maximum current : 18A for DC24V and 13A for AC230V
AF motor for inverter is designed for use with inverter.
It uses star (wye)( ) connection for small capacity range and delta ( Δ ) connection for middle capacity range and larger.
In addition, star (wye)-delta switch operation is possible using commercial power source.
Note : This drawing shows for a motor based on standard specification for domestic market.
Motor based on overseas standard shall be referred to us.
These should be furnished by the customer.
MCB: Molded case circuit breaker
Tr: Transfomer capacity 250-600VA, secondary voltage 200-220V
F: Fuse 3-5A
