    Note: The NXC regenerative low-harmonic drive incorporates an LCL filter instead of AC chokes and this instruction can be ignored. The AC input choke carries out several functions in the Vacon NX 6- and 12-pulse frequency converter. The input choke is needed as an essential component for motor control, to protect the input and DC-link components against abrupt changes of current and voltage as well as to function as a protection against harmonics.

    The motor terminals U, V, W and the DC-link/brake resistor terminals –/+ are live when Vacon NX is connected to mains, even if the motor is not running. The control I/O-terminals are isolated from the mains potential. How- ever, the relay outputs and other I/O-terminals may have a dangerous control voltage present even when Vacon NX is disconnected from mains.
