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.
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.
VFDs of 037G/045P or lower only need to be
configured with brake resistors, and VFDs of
045G/055P
–110G support optional built-in
brake units.
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.
