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.

Preface
Thank you for choosing DELTA’s multifunction VFD-EL Series. The VFD-EL Series is manufactured with high-quality components and materials and incorporate 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-EL User Manual on the CD supplied with the drive.

Danger:

• AC input power must be disconnected before any wiring to the AC motor drive is made.
• 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 turned off before opening the
• AC motor drive and wait ten minutes for the capacitors to discharge to safe voltage levels.
• Never reassemble internal components or wiring.
• 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.
• Ground the VFD-EL 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.
• VFD-EL series is used only to control variable speed of 3-phase induction motors, NOT for 1-phase
• motors or other purpose.
• VFD-EL series is the specific drive for the elevator door and other automatic door control, NOT for
• those devices that may cause personal injury, such as life support equipment or any life safety situation.
• To prevent drive damage, the RFI jumper connected to ground shall be cut off if the AC motor drive is
• installed on an ungrounded power system or a high resistance-grounded (over 30 ohms) power system
• or a corner grounded TN system.

WARNING

• DO NOT use Hi-pot test for internal components. The semi-conductor used in AC motor drive easily damage by high-pressure.
• 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.
• Only quality person is allowed to install, wire and maintain AC motor drive.

Caution:

• Some parameters settings can cause the motor to run immediately after applying power.
• 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. Only use AC motor drives within specification. Failure to comply may result in fire, explosion or electric shock. To prevent personal injury, please keep children and unqualified people away from the equipment.
• When the motor cable between 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.
• The rated voltage for AC motor drive must be ≤ 240V (≤ 480V for 460V models) and the mains supply current capacity must be ≤ 5000A RMS.

Price Range:- Rs 8000 - Rs 50000/Piece.
