Note: Using the braking resistor not provided by our company lead to the loss of the inverter or other
equipment damage, we will not bear the responsibility.

8.2.4 AC reactor

D6B/L/P series inverter in 30 kW or below grade can improve input power factor and suppress the harmonic
interference of inverter on the grid by using AC input reactor. When the power impedance is less than 2%(it
can be judged according to if the power capacity is 10 times larger than inverter capacity or if the power
capacity is greater than 100kVA). It is recommended to add in AC input reactor in between inverter and power
supply adopt it in following cases: Please refer to the below table when selecting the specifications of AC input
reactor.

8.2.5 DC reactor

D6B/L/P series inverter in 37 kW and over 37 kW power grade can improve input power factor and suppress
the harmonic interference of inverter on the grid by using DC reactor.
Please refer to the below table when selecting the specifications of DC reactor..
