A risk of fire exists if External braking resistors are not protected. External resistor packages must be protected from over temperature or the protective circuit shown, or equivalent, must be Drive5 ThermostatConnectorsPower On R (L1)S (L2)T (L3)Power SourceDB Resistor ThermostatPower OffMM(Input Contactor) MThree-PhaseAC Input!
