VFD-B Series
DELTA ELECTRONICS, INC. ALL RIGHTS RESERVED
Preface
Thank you for choosing DELTA’s high-performance VFD-B Series. VFD-B Series are
manufactured by adopting high-quality components, material and incorporating the latest
microprocessor technology available.
 Getting Started
This manual will be helpful in the installation, parameter setting, troubleshooting, and daily
maintenance of the AC motor drives. To guarantee safe operation of the equipment, read
the following safety guidelines before connecting power to the AC drives. Keep this
operating manual handy and distribute to all users for reference.
! WARNING
!
Always read this manual thoroughly before using VFD-B series AC Motor Drives.
!
DANGER! AC input power must be disconnected before any maintenance. Do
not connect or disconnect wires and connectors while power is applied to the
circuit. Maintenance must be performed by qualified technicians.
!
CAUTION! There are highly sensitive MOS components on the printed circuit boards.
These components are especially sensitive to static electricity. To avoid damage to
these components, do not touch these components or the circuit boards with metal
objects or your bare hands.
!
DANGER! A charge may still remain in the DC-link capacitor with hazardous voltages
even if the power has been turned off. To avoid personal injury, please ensure that
power has turned off before operating AC drive and wait ten minutes for capacitors to
discharge to safe voltage levels.
!
CAUTION! Ground the VFD-B using the ground terminal. The grounding method
must comply with the laws of the country where the AC drive is to be installed. Refer to
Basic Wiring Diagram.
!
DANGER! The AC drive may be destroyed beyond repair if incorrect cables are
connected to the input/output terminals. Never connect the AC drive output terminals
U/T1, V/T2, and W/T3 directly to the AC main circuit power supply.
!
CAUTION! The final enclosures of the AC drive must comply with EN50178. (Live
parts shall be arranged in enclosures or located behind barriers that meet at least the
requirements of the Protective Type IP20. The top surface of the enclosures or barrier
that is easily accessible shall meet at least the requirements of the Protective Type
IP40). (VFD-B series corresponds with this regulation.)
CAUTION! Heat sink may heat up over 70oC (158oF), during the operation. Do not
touch the heat sink.

2.2 Installation
CAUTION
The control, power supply and motor leads must be laid separately. They must not be
fed through the same cable conduit / trunking.
High voltage insulation test equipment must not be used on cables connected to the
drive.
Improper installation of the AC drive will greatly reduce its life. Be sure to observe the
following precautions when selecting a mounting location.
Failure to observe these precautions may void the warranty!
 Do not mount the AC drive near heat-radiating elements or in direct sunlight.
 Do not install the AC drive in a place subjected to high temperature, high humidity,
excessive vibration, corrosive gases or liquids, or airborne dust or metallic particles.
 Mount the AC drive vertically and do not restrict the air flow to the heat sink fins.
 The AC drive generates heat. Allow sufficient space around the unit for heat dissipation.

 General Wiring Information
Applicable Codes
All VFD-B AC drives except 015B21A, 015B23A and 075B23B 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 drive and the
motor nameplate for electrical data.
The "Line Fuse Specification" in Appendix B, lists the recommended fuse part number for
each B-Series part number. These fuses (or equivalent) must be used on all installations
where compliance with U.L. standards is a required.

APPENDIX B and select the correct
fuse with rated current. NFB is
optional.

drive, this will reduce the operating
life cycle of the AC drive.
Input AC
Line
Reactor
(Optional)
In order to improve the input power
factor, reduces harmonics and
protection from AC line
disturbances. (Surge, switching
spike, power flick, etc.) AC line
reactor should be installed when the
power supply capacity is 500kVA or
more and exceeds 6 times of the
inverter capacity, or the wiring
distance within 10m.
Zero-phase
Reactor
(Ferrite
Core
Common
Choke)
(Optional)
Zero phase reactors are used to
reduce radio noise specify when the
audio equipments installed near the
inverter. Good effective for noise
reduction on both the input and
output sides. Attenuation quality is
good in a wide range from AM band
to 10Mhz. Appendix B for specifies
zero phase reactors. (RF220X00A)
EMI filter
(Optional)
To reduce the electromagnetic
interference. Please refer to
Appendix B for detail.
