Delta Electronics AC Motor Drive VFD-EL User manual

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.
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-EL 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 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-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.
6. VFD-EL series is used only to control variable speed of 3-phase induction motors, NOT for 1-
phase motors or other purpose.
7. VFD-EL series shall NOT be used for life support equipment or any life safety situation.

WARNING!
1. DO NOT use Hi-pot test for internal components. The semi-conductor used in AC motor drive
easily damage by high-voltage.
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. 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.
2. Some parameters settings can cause the motor to run immediately after applying power
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 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 AC motor drive must be ≤240V (≤480V for 460V models) and the mains
supply current capacity must be ≤5000A RMS.

Chapter 1 Introduction
The AC motor drive should be kept in the shipping carton or crate before installation. In order to
retain the warranty coverage, the AC motor drive should be stored properly when it is not to be used
for an extended period of time. Storage conditions are:
CAUTION!
1. Store in a clean and dry location free from direct sunlight or corrosive fumes.
2. Store within an ambient temperature range of -20 °C to +60 °C.
3. Store within a relative humidity range of 0% to 90% and non-condensing environment.
4. Store within an air pressure range of 86 kPA to 106kPA.
5. DO NOT place on the ground directly. It should be stored properly. Moreover, if the surrounding
environment is humid, you should put exsiccator in the package.
6. DO NOT store in an area with rapid changes in temperature. It may cause condensation and
frost.
7. If the AC motor drive is stored for more than 3 months, the temperature should not be higher
than 30 °C. Storage longer than one year is not recommended, it could result in the degradation
of the electrolytic capacitors.
8. When the AC motor drive is not used for longer time after installation on building sites or places
with humidity and dust, it’s best to move the AC motor drive to an environment as stated above.

RFI Jumper
RFI Jumper: The AC motor drive may emit the electrical noise. The RFI jumper is used to suppress
the interference (Radio Frequency Interference) on the power line.
Main power isolated from earth:
If the AC motor drive is supplied from an isolated power (IT power), the RFI jumper must be cut off.
Then the RFI capacities (filter capacitors) will be disconnected from ground to prevent circuit damage
(according to IEC 61800-3) and reduce earth leakage current.
CAUTION!
1. After applying power to the AC motor drive, do not cut off the RFI jumper. Therefore,
please make sure that main power has been switched off before cutting the RFI jumper.
2. The gap discharge may occur when the transient voltage is higher than 1,000V. Besides,
electro-magnetic compatibility of the AC motor drives will be lower after cutting the RFI
jumper.
3. Do NOT cut the RFI jumper when main power is connected to earth.
4. The RFI jumper cannot be cut when Hi-pot tests are performed. The mains power and
motor must be separated if high voltage test is performed and the leakage currents are
too high.
5. 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.

CAUTION!
1. Operating, storing or transporting the AC motor drive outside these conditions may cause
damage to the AC motor drive.
2. Failure to observe these precautions may void the warranty!
3. Mount the AC motor drive vertically on a flat vertical surface object by screws. Other directions
are not allowed.
4. The AC motor drive will generate heat during operation. Allow sufficient space around the unit
for heat dissipation.
5. The heat sink temperature may rise to 90°C when running. The material on which the AC motor
drive is mounted must be noncombustible and be able to withstand this high temperature.
6. When AC motor drive is installed in a confined space (e.g. cabinet), the surrounding
temperature must be within 10 ~ 40°C with good ventilation. DO NOT install the AC motor drive
in a space with bad ventilation.
7. Prevent fiber particles, scraps of paper, saw dust, metal particles, etc. from adhering to the
heatsink.
8. When installing multiple AC more drives in the same cabinet, they should be adjacent in a row
with enough space in-between. When installing one AC motor drive below another one, use a
metal separation between the AC motor drives to prevent mutual heating.
