JR6000 series inverters from 18.5kW to 90kW
(380V) are equipped with internal DC reactors
for the improvement of power factors and the
avoidance of damage from high input current to
the rectifying components because of the
high-capacity transformer. The inverter can also
cease the damage to the rectifying components
which are caused by supply net voltage
transients and harmonic waves of the loads.

JR6000 series inverters below 1 5 kW (380V) are
equipped with internal braking unit. In order to
dissipate the regenerative energy generated by
dynamic braking, the braking resistor should be
installed at (+) and P R terminals.
• The wire length of the braking resistor should
be less than 5m.
• Please pay attention to safety prevention and
smooth ventilation when installing braking
resistors because the temperature will rise for
the heat releasing.
• The (+) and (-) terminal of the braking units
corresponds to the (+) and (-) terminal of the
inverter when the external braking unit is
connected. Connect braking resistor to the BR1
and BR2 terminal of the braking unit.
• The wiring length between the ( +) , (-) terminals
of the inverter and the (+) ， (-) terminals of the
braking units should be no more than 5m ， and
the distributing length among BR1 and BR2 and
the braking resistor terminals should be no more
than 10m.
