Name
Description
Cable
Accessory for signal transmission
Breaker
Device for electric shock prevention and protection against
short-to-ground that may cause current leakage and fire.
Select residual-current circuit breakers (RCCBs) that are
applicable to VFDs and can restrict high-order harmonics,
and of which the rated sensitive current for one VFD is larger
than 30 mA.
Input reactor
Accessories used to improve the current adjustment
coefficient on the input side of the VFD, and thus restrict high-
order harmonic currents.
Standard model VFDs 132G3 and higher can be directly
connected to external DC reactors.
DC reactor
Input filter
Accessory that restricts the electromagnetic interference
generated by the VFD and transmitted to the public grid
through the power cable. Try to install the input filter near the
input terminal side of the VFD.
or
Brake unit or brake
resistor
Accessories used to consume the regenerative energy of the
motor to reduce the deceleration time.
SP model VFDs only need to be configured with brake
resistors.
Output filter
Accessory used to restrict interference generated in the
wiring area on the output side of the VFD. Try to install the
output filter near the output terminal side of the VFD.
Output reactor
Accessory used to lengthen the valid transmission distance
of the VFD, which effectively restrict the transient high voltage
generated during the switch-on and switch-off of the IGBT
module of the VFD.
D.3 Power supply
Refer to the electrical installation.
Ensure that the voltage class of the VFD is consistent with that of the grid.
D.4 Cables
D.4.1 Power cables
The sizes of the input power cables and motor cables must meet the local regulation.
⚫ The input power cables and motor cables must be able to carry the corresponding load currents.
⚫ The maximum temperature margin of the motor cables in continuous operation cannot be lower
