■ Wiring (Main Circuit Terminal)
Ground marking
Three-phase 400V 0.75～3.7kW
■ Connected Device, Wire Size and Main Circuit Terminal Tightening Torque
Note 1) If the breaker's overcurrent trip is a magnetic type, the device could overheat
due to higher harmonics. Use a load rate of 50% or less in this case.
Note 2) When using an installed circuit breaker with motor protection, remove it.
Note 3) Always connect protective devices such as fuse for overcurrent, short circuits
and leakage protection to the input.

≪Precautions for Using Regenerative Brakes≫
1. When using regenerative brakes, set the parameter P019 setting data to "0".
The brakes will not activate when the factory setting "1" is set.
2. Always use the Panasonic-dedicated option for the brake resistor.
3. The regenerative brake specifications are shown below. Carefully consider the working
conditions before using these brakes.
Note that the inverter could be damaged if the specifications are exceeded.
・Maximum duty factor (%ED): 5% ・Maximum working time: 5s
・Maximum torque: 100%
