Goodrive350 IP55 High-ingress Protection Series VFD
Optional peripheral accessories
-350-
To ensure safety, you can configure an electromagnetic contactor on the input side to control
the switch-on and switch-off of the main circuit power, so that the input power supply of the
VFD can be effectively cut off when a system fault occurs.

Note:
Parameters of the optional accessories described in the preceding table are ideal values.
You can select accessories based on the actual market conditions, but try not to use those with
lower values.
D.6 Reactors
When the voltage of the grid is high, the transient large current that flows into the input power
circuit may damage rectifier components. You need to configure an AC reactor on the input
side, which can also improve the current adjustment coefficient on the input side.
When the distance between the VFD and motor is longer than 50 m, the parasitic capacitance
between the long cable and ground may cause large leakage current, and overcurrent
protection of the VFD may be frequently triggered. To prevent this from happening and avoid
damage to the motor insulator, compensation must be made by adding an output reactor.
When a VFD is used to drive multiple motors, take the total length of the motor cables (that is,
sum of the lengths of the motor cables) into account. When the total length is longer than 50 m,
an output reactor must be added on the output side of the VFD. If the distance between the
VFD and motor is 50 m to 100 m, select the reactor according to the following table. If the
distance is longer than 100 m, contact INVT's technical support technicians.
