DELTA ELECTRONICS, INC. ALL RIGHTS RESERVED
Preface
Thank you for choosing DELTA’s high-performance VFD-F Series. VFD-F 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-F series AC Motor Drives.
! Ensure that VFD-F is grounded in a correct way before putting it into use.
! 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, do not remove the cover of the
AC drive until all “DISPLAY LED” lights on the digital keypad are off. Please note that there
are live components exposed within the AC drive. Do not touch these live parts.
!
CAUTION! Ground the VFD-F 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-F series corresponds with this regulation.)
!
CAUTION! The rated voltage for the AC motor drive must be
≤
240V for 230V models (
≤
480V for 460V models) and the mains supply current capacity must be
≤
5000A RMS
(
≤
10000A RMS for the
≥
40hp (30kW) models)
CAUTION! Heat sink may heat up over 70
o
C (158
o
F), during the operation. Do not touch
the heat sink.
