It is necessary to install the electromagnetic contactor in the input side to control the switching
on and off safety of the main circuit. It can switch off the input power supply when system
faults.
For single phase: "Suitable for use on a circuit capable of delivering not more than 5000 rms
symmetrical amperes, 250 volts maximum when protected by fuse, see following table for fuse
information." or equivalent.

Integral solid-state short circuit protection does not provide branch circuit protection. Branch
circuit protection must be provided in accordance with the National Electrical Code and any
additional local codes.
C.5 Reactors
High current in the input power circuit may cause damage to the rectifying components. It is
appropriate to use AC reactor in the input side for the avoidance of high-voltage input of the
power supply and improvement of the power factors.
If the distance between the VFD and the motor is longer than 50m, frequent overcurrent
protection may occur to the VFD because of high leakage current caused by parasitic
capacitance effects from the long cables to the ground. In order to avoid the damage of the
motor insulation, it is necessary to add reactor compensation.
