short-circuit. To ensure safe use, special attention must be paid to the installation and
placement of the breakers. Follow the manufacturer’s instructions.
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 fault.
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 inverter and the motor is longer than 50m, frequent high current spikes may occur to
the inverter 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.
Note:
1. The rated derate voltage of the input reactor is 2%±15%.
2. The power factor of the input side is better than 90% when using a DC reactor.
3. The rated derate voltage of the output reactor is 1%±15%.
4. The above options are external, the customer should indicate when purchasing.
C.6 Filters
The input EMC filter can reduce the RFI noise of the inverter to surrounding equipment.
