3.2 Wiring of peripheral elements
 Power supply
The inverter shall be provided with power in accordance with specification
of input power supply designated by this operating manual
 Air switch
1) When the frequency inverter is maintained or not in use for a long time,
2) the air switch will separate the frequency inverter from the power
supply;
3) When the input side of the frequency inverter has failures like short
circuit, the air switch can provide protection.
 Contactor
It can conveniently control power-supply and power disconnection of the
inverter, and the power-on and power-off of the motor.
 AC reactor
1) To promote power factor;
2) To reduce harmonic input of the inverter against the grid;
3) Weaken influenced caused by unbalanced voltage of three-phase power
supply.
 Brake resistance
When the motor is at the dynamic braking status, it can avoid producing over
high pumping voltage in the DC loop.
