CAUTION
1. The 18.5K or more is not equipped with the built-in brake resistor and brake transistor marked *. The brake transistor is
provided for the 15K or less and the built-in brake resistor for the 5.5K or less.
2. Always earth (ground) the inverter and motor.
3. **: When using an external thermal relay protection, set "1" (external thermal relay valid) in Pr. 876. (factory setting)

Jumper: Remove this jumper when connecting
the FR-HEL/BEL.
Jumper: Remove this jumper when
connecting the FR-ABR.
(5.5K or less only)
Avoid frequent ON-OFF.
Repeated inrush current at power on
will shorten the converter life.
(switching life is about 100,000 times)
