Compatibility with Y-△ motor and others
1. Can I connect the FR-F320-15K inverter and Y-△ motor? (Used for exhaust fan)
2. If 1. above is possible, can I connect four 3.7 kW Y-△ motors? (Used for exhaust fan)
3. What are the precautions on designing the circuit?
4. Can you repair the FR-F320-15K (manufactured in 1987)?
5. What is the replacement of the FR-F320-15K?

Answer
1. You can connect them using △ connection.
2. No problem with connecting four Y-△ motors. (Connect all four motors using △ connection.) (Note that the inverter rated current must be "3.7 kW motor rated current × 4 × 1.1" or higher.)
3. Since multiple motors are used, connect an external thermal for each of them. (This is because the inverter cannot detect overheat due to overcurrent of each motor.) Also, use the terminal OH (external input terminal) to connect thermal contacts in series. (To detect motor overheat and stop the inverter)
4. Yes. Consult the nearest Mitsubishi FA Center for repair period.
5. The FR-A120-15K is the replacement because it is used for the exhaust fan.
