Always create an electrical and mechanicalCurrent loopinterlock for MCl and MC2.(2) If a power failure occurs and the start signal (start switch)is retained. the inverter will automatically resume operation when the power is restored.If the machine must be prevented from restarting with power restoration, install a magneticccntector MC on the primary side of the inverter, and design a sequence to prevent the startsignal from turning ON.(3) Use two contacts in parallel or a twin contact to prevent an imperfect contact for the inputsignal of the control circuit.(4) Do not input a voltage on the contact input terminal (STF, etc.) of the control circuit.(5) Do not apply the voltage directly onto the alarm output signal terminal (8, C). Pass thevoltage through a relay coil or ramp.(6) When directly connecting the open collector output such as that from a sequence controllerinto the inverter input terminal. make sure that a backflow current does not occur. - -15-

Countermeasures(1) Insert a diode to preventthe backflow current.(2) Use an all-point isolatedtype output unit.(Ex.
