Circuit b Earth
leakage protection
Prevent from electric shock and protect the
power supply and the cables system from
overcurrent when short circuits occur. Please
select an additional earth leakage protection with
the function of reducing high order harmonic and
with the rated sensitive current above 30mA.
Input reactor
This device is used to improve the power factor
of the input side of the inverter and control the
higher harmonic current.
EMC filter
Control the electromagnetic interference
generated from the inverter. For the inverters
3PH 400V
≥
4 kW and 3PH 220V
≥
1.5 kW is
embedded. For the inverters 1PH 230V / 3PH
400V
≤
2.2 kW and 3PH 220V
≤
0.75 kW is
optional (installed in parallel with the input of the
inverter, and placed under it)
Braking resistors
Shorten the DEC time
Choke
Prolongues the effective transimitting distance of
the inverter because controls the sudden high
voltage provoqued when switching on/off the
IGBTs of the inverter. Recommended when the
cable distance between the inverter and the
motor is between 50m and 100m. Please install
close to the output terminals of the inverter.
Output Sine wave filter (LC
Filter)
Prolongues the effective transimitting distance of
the inverter because controls the sudden high
voltage provoqued when switching on/off the
IGBTs of the inverter. Recommended when the
cable distance between the inverter and the
motor is longer than 100m. Please install close to
the output terminals of the inverter.
Lateral Covers
Apply to severe environment and improve
protective effect.
Derate 10% of the machine.
C.2 Power supply
Check that the voltage degree of the inverter complies with the voltage of the
supply power voltage.
