400V Class Inverters
tables specify the braking options for
400V class X200 inverters and the
braking torque for each option. You can
connect a single braking unit to the
inverter, or two braking units for
additional braking torque.
Use one BRD-EZ3 braking unit for the
braking torque listed in the following
table.
