9.2.3 Compliance with Peripheral devices
Use the UL listed fuses at connecting to power supply.
Refer to the instruction manual about selecting the rating of them.
Short circuit test is performed under the condition of the power supply short-circuit currents in
below.
These currents and fuse currents depend on the drive motor capacities.

9.2.4 Motor thermal protection
Selects the electronic thermal protection characteristics that fit with the ratings and characteristics
of the motor. In case of multi motor operation with one inverter, thermal relay should be connected
to each motor.
