DC Reactor (IP Level: IP00)
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 DC/+1 and +2/B1. Remove the jumper, as shown in the
figure below, before installing the DC reactor.
