Summary of Contents for Delta VFD-B

  • Page 4 Ground the VFD-B using the ground terminal. The grounding method must comply with the laws of the country where the AC motor drive is to be installed. Refer to the Basic Wiring Diagram. VFD-B 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 the AC motor drive is easily damaged by high-pressure. 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.

  • Page 37 Chapter 2 Installation and Wiring|VFD-B Series DO NOT connect phase-compensation capacitors or surge absorbers at the output terminals of AC motor drives. With long motor cables, high capacitive switching current peaks can cause over-current, high leakage current or lower current readout accuracy. To prevent this, the motor cable should be less than 20m for 3.7kW models and below.
