DC Reactor 
A  DC  reactor  can  also  improve  the  power  factor,  reduce  input  current,  and  reduce  interference 
generated from the motor drive. A DC reactor stabilizes the DC bus voltage. Compared to an AC input 
reactor, the advantages are smaller size, lower price, and lower voltage drop (lower power dissipation) 
Installation 
Install the DC reactor between terminals +2/DC+ and +1/DC+. Remove the jumper (shown below) 
before installing the DC reactor.
