    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. After disconnecting the frequency converter from the mains, wait until the fan stops and the indicators on the keypad go out (if no keypad is attached see the indicators on the cover).

    10 • vacon SAFETY The earth fault protection inside the frequency converter protects only the converter itself against earth faults in the motor or the motor cable. It is not intended for personal safety. Due to the high capacitive currents present in the frequency converter, fault current protective switches may not function properly.

    TECHNICAL DATA Introduction Figure 4-1 presents the block diagram of the Vacon NX_ frequency converter. The frequency converter mechanically consists of two units, the Power Unit and the Control Unit. Pictures of the mechanical assemblage on pages 57 to 65.
  • Page 20 20 • vacon TECHNICAL DATA The control keypad constitutes a link between the user and the frequency converter. The control keypad is used for parameter setting, reading status data and giving control commands. It is detachable and can be operated externally and connected via a cable to the frequency converter. Instead of the control keypad, also a PC can be used to control the frequency converter if connected through a similar cable.
