DELTA ELECTRONICS, INC. ALL RIGHTS RESERVED
Preface
Thank you for choosing DELTA’s VFD-L series AC Drive. The VFD-L series is
manufactured using high-quality components, material and incorporating the
latest microprocessor technology available.
Getting Started
This manual will help in 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 handy and distribute to all users for reference.
! WARNING
!Always read this manual thoroughly before using VFD-L 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, 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-L 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.

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.
