  • Page 8: Safety

    THE ELECTRICAL INSTALLATION War nings The components of the power unit of the inverter are l ive when the Vacon NX is connected to DC supply. Coming into contact with this vol tage is extremel y danger ous and may cause death or sever e injur y. The control unit is isolated from mains potential.
  • Page 9 • 7 Ear thing and ear th fault pr otection The Vacon NX inverter must always be earthed with an earthing conductor connected to the earthing terminal. The earth fault pr otection inside the inverter only protects the inverter against earth faults in the motor or the motor cable.

  • Page 10: Eu Directive

    (for example, the EMC directive and other possible so- called new method directives). Vacon NX inverters carry the CE label as a pr oof of compliance with the Low Voltage Directive (LVD) and the Electro Magnetic Compatibility (EMC) directive. SGS FIMKO has acted as the Competent Body.

Maintenance In normal conditions, Vacon NX inverters are maintenance- free. However, we recommend to clean the heatsink with compressed air whenever necessary.

  • Page 14: Technical Data

    TECHNICAL DATA Intr oduction The figure below presents the block diagram of the Vacon NX inverter. The inverter mechanically consists of two units, the Power Unit and the Control Unit. The Power Unit contains an inverter bridge which consists of IGBT switches and produces a symmetrical, 3- phase PWM- modulated AC voltage to the motor.
  • Page 15 Instead of the control keypad, a PC can be used to contr ol the inverter if connected through a similar cable (VACON RS232PC –1.5M). The basic control interface and the parameters (the Basic Application) are easy to use. If a more versatile interface or parameters ar e required, a more suitable application can be chosen from the "All in One+"...

    The minimum dimensions of the Cu- cables are shown in Table 6- 4. If the motor temperature protection of the drive (see Vacon All in One Application Manual) is used as an overload protection, the cable shall be chosen accordingly. If three or more cables are used in parallel for bigger units, each cable requires a separate overload pr otection.
