Description
Cables
Device to transfer the electronic signals
Breaker
Device to prevent the inverter from electric
shock and protect the power supply and the
cables system from overcurrent when short
circuits occur. (Select the breaker with the
function of reducing high order harmonic and
the rated sensitive current to 1 inverter
should be above 30mA).
Input reactor
Device to improve the power factor of the
input side of the inverter and control the
higher harmonic current.
Input filter
Control the electromagnetic interference
generated from the inverter, please install
close to the input terminal side of the
inverter.
or
Brake unit or resistor
Shorten the DEC time
The inverters≤15kW need
brake resistors
and the inverters ≥18.5kW need
brake units.
Output filter
Control the interference from the output side
of the inverter and please install close to the
output terminals of the inverter.
Output reactor
Prolong the effective transmitting distance of
the inverter to control the sudden high
voltage when switching on/off the IGBT of
the inverter.
D.3
Power supply
Refer to
Electrical installation
.
Check that the voltage degree of the inverter complies with the voltage of the
supply power voltage.
D.4
Cables
D.4.1 Power cables
Dimension the input power and motor cables according to local regulations.
•
The input power and the motor cables must be able to carry the corresponding load currents.
