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.
This manual is to be used for the installation, parameter setting, troubleshooting, and daily
maintenance of the AC motor drive. To guarantee safe operation of the equipment, read the
following safety guidelines before connecting power to the AC motor drive. Keep this operating
manual at hand and distribute to all users for reference.
To ensure the safety of operators and equipment, only qualified personnel familiar with AC motor
drive are to do installation, start-up and maintenance. Always read this manual thoroughly before
using VFD-B series AC Motor Drive, especially the WARNING, DANGER and CAUTION notes.
Failure to comply may result in personal injury and equipment damage. If you have any questions,
please contact your dealer.
PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.
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.
WARNI NG!
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 qualified persons are allowed to install, wire and maintain AC motor drives.
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).

2.4 Wiring
After removing the front cover, check if the power and control terminals are clear of debris. Be sure
to observe the following precautions when wiring.
General Wiring Information
Applicable Codes
All VFD-B series are Underwriters Laboratories, Inc. (UL) and Canadian Underwriters Laboratories
(cUL) listed, and therefore comply with the requirements of the National Electrical Code (NEC) and
the Canadian Electrical Code (CEC).
Installation intended to meet the UL and cUL requirements must follow the instructions provided in
“Wiring Notes” as a minimum standard. Follow all local codes that exceed UL and cUL
requirements. Refer to the technical data label affixed to the AC motor drive and the motor
nameplate for electrical data.
The "Line Fuse Specification" in Appendix B, lists the recommended fuse part number for each
VFD-B Series part number. These fuses (or equivalent) must be used on all installations where
compliance with U.L. standards is a required.

2.4.1 Basic Wiring
Make sure that power is only applied to the R/L1, S/L2, T/L3 terminals. Failure to comply
may result in damage to the equipment. The voltage and current should lie within the range
as indicated on the nameplate.
Check the following items after completing the wiring:
1. Are all connections correct?
2. No loose wires?
3. No short-circuits between terminals or to ground?
A charge may still remain in the DC bus capacitors with hazardous voltages even if the power has
been turned off. To prevent personal injury, please ensure that the power is turned off and wait ten
minutes for the capacitors to discharge to safe voltage levels before opening the AC motor drive.
DANGER!
1. All the units must be grounded directly to a common ground terminal to prevent electric shock,
fire and interference.
2. Only qualified personnel familiar with AC motor drives are allowed to perform installation, wiring
and commissioning.
3. Make sure that the power is off before doing any wiring to prevent electric shocks.
Basic Wiring Diagrams
Users must connect wires according to the circuit diagrams on the following pages. Do not plug a
modem or telephone line to the RS-485 communication port or permanent damage may result. The
pins 1 & 2 are the power supply for the optional copy keypad PU06 only and should not be used for
RS-485 communication.
