Goodrive350 series high-performance multi-function inverter Appendix D
-312-
Accessory for signal transmission
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 inverters and can
restrict high-order harmonics, and of which
the rated sensitive current for one inverter is
larger than 30 mA.
Accessories used to improve the current
adjustment coefficient on the input side of
the inverter, and thus restrict high-order
harmonic currents.
Inverters of 380 V, 132 kW or higher and 660
V series can be directly connected to
external DC reactors.
Accessory that restricts the electromagnetic
interference generated by the inverter and
transmitted to the public grid through the
power cable. Try to install the input filter near
the input terminal side of the inverter.
Brake unit or brake
resistor
Accessories used to consume the
regenerative energy of the motor to reduce
the deceleration time.
Inverters of 380 V, 37 kW or lower need only
to be configured with brake resistors, those
of 380V, 132 kW or higher and 660 V series
also need to be configured with brake units,
and those of 380V, 45 kW to 110 kW can be
configured with optional built-in brake units.
Accessory used to restrict interference
generated in the wiring area on the output
side of the inverter. Try to install the output
filter near the output terminal side of the
