Preface

Thank you for choosing DELTA’s high-performance VFD-B Series. The VFD-B Series is
manufactured with high-quality components and materials and incorporates the latest microprocessor
technology available.

 Getting Started

This quick start will be helpful in the installation and parameter setting of the AC motor drives. To
guarantee safe operation of the equipment, read the following safety guidelines before
connecting power to the AC motor drives. For detail information, refer to the VFD-B User Manual
on the CD supplied with the drive.

DANGER!

1. AC input power must be disconnected before any wiring to the AC motor drive is made.

2. A charge may still remain in the DC-link capacitors with hazardous voltages, even if the power has
been turned off. To prevent personal injury, please ensure that power has been turned off before
opening the AC motor drive and wait ten minutes for the capacitors to discharge to safe voltage levels.

3. Never reassemble internal components or wiring.

4. The AC motor drive may be destroyed beyond repair if incorrect cables are connected to the
input/output terminals. Never connect the AC motor drive output terminals U/T1, V/T2, and W/T3
directly to the AC mains circuit power supply.

5. 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.

6. VFD-B series is used only to control variable speed of 3-phase induction motors, NOT for 1-phase
motors or other purpose.

7. VFD-B series shall NOT be used for life support equipment or any life safety situation.

WARNING!

1. DO NOT use Hi-pot test for internal components. The semi-conductor used in the AC motor drive is
easily damaged by high-pressure.

2. 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.

3. Only quality person is allowed to install, wire and maintain AC motor drive.

CAUTION!

1. Some parameter settings will cause the motor to run immediately after applying power.

2. DO NOT install the AC motor drive in a place subjected to high temperature, direct sunlight, high

humidity, excessive vibration, corrosive gases or liquids, or airborne dust or metallic particles.

3. Only use AC motor drives within specification. Failure to comply may result in fire, explosion or electric

shock.

4. To prevent personal injury, please keep children and unqualified people away from the equipment.

5. When the motor cable between the AC motor drive and motor is too long, the layer insulation of the

motor may be damaged. Please use a frequency inverter duty motor or add an AC output reactor to
prevent damage to the motor. Refer to appendix B Reactor for details.

6. The rated voltage for the AC motor drive must be ≤240V (≤480V for 460V models, ≤600V for 575V

models) and the mains supply current capacity must be ≤5000A RMS (≤10000A RMS for the ≥40hp
(30kW) models).
