  16. Selector Guide – How to Select? • System voltage • Motor current and connection • Starting conditions • Options and control voltage

  17. Selector Guide – How to Select? • System voltage • 400 230 - 400 VAC, 50/60Hz, +10% -15% • 480 480 VAC, 50/60Hz, +10% -15% • 600 600 VAC, 50/60Hz, +10% -15% • 690 690 VAC, 50/60Hz, +10% -15% • 1000 1000 VAC, 50/60Hz, +10% -15%Models: 105A, 170A, 210A, 310A, 390A, 460A.

  18. Selector Guide – How to Select? • Motor current and connection • Starter current ≥ motor FLA! ! !

  19. Selector Guide – How to Select? • Motor current and connection • In line/Inside delta • When soft starter is connected “inside delta” lower current is running through the soft starter. Soft starter MUST Be connected exactly as shown in the manual

  20. Selector Guide – How to Select? • Motor current and connection • In line/Inside delta • Advantages: • Smaller dimensions • Less expensive Soft Starter • Disadvantages: • Six wire to the motor – more complicated wiring. • No pulse start • No curve selection (Curve 0! Only) • No energy save • No slow speed • No phase sequence “off” mode. • Although current inside delta is reduced by 1.73 (√3), Soft starter current is reduced by 1.5.For example: for a 870A motor, you can choose a 580A soft starter when connected “inside delta”

  21. Selector Guide – How to Select? • Starting conditions • The RVS-DN is able to start at 4xIn, 30 seconds at 50°C

  22. Selector Guide – How to Select? • Options: • Communication - RS-485 (Modbus) • Communication – Profibus • Insulation tester • Analog card – Thermistor in and Analog out • Harsh environment treatment. • Preparation for Bypass contactor • Line and load bus bars at bottom • Remote panel mounting replacing the original panel. • Russian characters LCD display • Marine approval • UL & cUL approval • Tachometer card for special drive systems

  23. Bypass Contactor • Models 8-820A can operate continuously without a bypass contactor • All models from RVS-DN 950A and up and RVS-DN 1000V must be implemented with a bypass contactor • Bypass preparation is standard in models RVS-DN 85-170A.
