Summary of Contents for Delta VFD-EL Series

  • Page 4 AC motor drive is to be installed. Refer to the Basic Wiring Diagram. VFD-EL series is used only to control variable speed of 3-phase induction motors, NOT for 1- phase motors or other purpose.
  • Page 5 WARNING! DO NOT use Hi-pot test for internal components. The semi-conductor used in AC motor drive easily damage by high-voltage. There are highly sensitive MOS components on the printed circuit boards. These components are especially sensitive to static electricity. To prevent damage to these components, do not touch these components or the circuit boards with metal objects or your bare hands.

    Chapter 1 Introduction| RFI Jumper RFI Jumper: The AC motor drive may emit the electrical noise. The RFI jumper is used to suppress the interference (Radio Frequency Interference) on the power line. Main power isolated from earth: If the AC motor drive is supplied from an isolated power (IT power), the RFI jumper must be cut off. Then the RFI capacities (filter capacitors) will be disconnected from ground to prevent circuit damage (according to IEC 61800-3) and reduce earth leakage current.
