When installing a thermal relay to the cooling fan of the vector-control dedicated motors (SF-
V5RU), use the following recommended thermal relay settings.

*1 Power (current) at 50Hz/60Hz.
*2 The cooling fan is equipped with a thermal protector. The cooling fan stops when the coil temperature exceeds
*2 The cooling fan is equipped with a thermal protector. The cooling fan stops when the coil temperature exceeds
the specified value in order to protect the fan motor. A restrained cooling fan or degraded fan motor insulation
may causes the rise in coil temperature. The fan motor re-starts when the coil temperature drops to normal.
may causes the rise in coil temperature. The fan motor re-starts when the coil temperature drops to normal.
*3 The voltage and input values are the standard specifications of the cooling fan in free air. When the cooling fan
is used with a motor, it requires more energy to perform its work, and thus the above input values become
slightly larger. The cooling fan can, however, be used as it is without causing problems. When a thermal relay is
to be prepared at the customer's side, use the recommended thermal relay settings.
