Customer to prepare.
-This diagram shows cases for motors with standard Japanese domestic specifications. Please consult with us for motors with
overseas specifications.
-When inverter-driving a 400V class 3-phase motor or a 400V class high-efficiency, 3-phase motor, measures must be taken
with motor insulation.
In the case of
With axial fan (totally enclosed, ventilated types)
, note the following items.
-Also connect a power source to the axial fan.
-For an indoor 400V class ( except flameproof type ), the axial fan power source voltage will be 200V class. For special specifications,
specifications may differ from the above. Check the manufacturing specifications.
-Connect the fan so that it rotates in the same direction as that shown on the nameplate for direction of rotation.
(Normally, the air from the fan will blow in a direction from the anti-load side to the load side.)
-When the motor is shut down for a long period, also shut down the axial fan motor.
-Wire the mounted thermostat.
-Thermostat specification: Terminal symbols: T1, T2 and P1, P2 Operating function: Normal close (b contact point)
Operating temperature: 135
℃
(for thermal class 155 (F)) Maximum current: DC 24V, 18A; AC 230V, 13A
