braking resistors or units before connecting them with the inverter.
 Do not connect the braking resistor with other terminals except for PB and
(-). Do not connect the braking unit with other terminals except
for(+)and(-).Damage to the inverter or braking circuit or fire may occur.
 Connect the braking resistor or braking unit with the inverter according to the
diagram. Incorrect wiring may cause damage to the inverter or other
devices.
Goodrive300 series inverters below 30kW (including 30kW) need internal braking units and
the inverters above 37kW need external braking unit. Please select the resistence and
power of the braking resistors according to actual utilization.
D.8.1.1 AC 3PH 380V(-15%)~440V(+10%)
The inverters of 380V (≤30kW) have embedded braking units but the inverters of 380V
(≥37kW) have optional braking units. Please select the braking resistor according to actual
operation.
