    Can I use a GFCI on the ATV12 ?

    Issue:
    Can I use a GFCI on the ATV12 ?
     
    Product Line:
    ALTIVAR 12

    Environment:
     All

    Cause:
    GFCI breaker tripping out

    Resolution:
    Because drives produce high level of leakage current, and depending of the sensibility of the breaker, tripping can occur.
    At the start up of the drive, the capacitor bank is charging and we see the peak of leakage current. This peak is higher when there is more than one drive after the breaker.
    Also, it's dependant on many installation parameters such as motor cable type, motor cable length, switching frequency, motor, ground connection.

    To avoid the random tripping of breaker due to earth leakage it is recommended to use GFCI called full immunized type A "SI" which is reinforced against high frequency leakage current.
