Delta Electronics VFD S 115V Series User manual

Preface
Thank you for choosing DELTA’s high-performance VFD-S Series. The VFD-S 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-S 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 been 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-S 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-S series is used only to control variable speed of 3-phase induction motors, NOT for 1-
phase motors or other purpose.
7. VFD-S 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 the AC motor
drive is easily damaged by high-pressure.
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 personnel are allowed to install, wire and maintain AC motor drive.
CAUTION!
1. Some parameter settings will cause the motor to run immediately after applying power.
2. 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.
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 the 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 the AC motor drive must be ≤240V for 230V models (≤120V for 115V
models, ≤480V for 460V models) and the mains supply current capacity must be ≤5000A RMS
(≤10000A RMS for the ≥40hp (30kW) models).

1.4 Storage
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:
Store in a clean and dry location free from direct sunlight or corrosive fumes.
Store within an ambient temperature range of -20 °C to +60 °C.
Store within a relative humidity range of 0% to 90% and non-condensing environment.
Store within an air pressure range of 86kPa to 106kPa.
CAUTION!
1. DO NOT store in an area with rapid changes in temperature. It may cause condensation and
frost.
2. 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.

Chapter 1 Introduction|VFD-S Series
Revision August 2008, SE09, SW V2.61 1-5
3. 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.
4. When the AC motor drive is not used for a long 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.

Chapter 2 Installation and Wiring
2.1 Ambient Conditions
Install the AC motor drive in an environment with the following conditions:
Operation Air Temperature: -10 ~ +40°C (14 ~ 104°F), Non-condensing
and not frozen
Relative Humidity: <90%, no condensation allowed
Atmosphere pressure: 86 ~ 106 kPa
Installation Site Altitude: <1000m
Vibration: <20Hz: 9.80 m/s2(1G) max
20 ~ 50Hz: 5.88 m/s2(0.6G) max
Storage
Transportation
Temperature: -20°C ~ +60°C (-4°F ~ 140°F)
Relative Humidity: <90%, no condensation allowed
Atmosphere pressure: 86 ~ 106 kPa
Vibration: <20Hz: 9.80 m/s2(1G) max
20 ~ 50Hz: 5.88 m/s2(0.6G) max
Pollution Degree 2: good for a factory type environment.
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!
2.2 Installation
1. Mount the AC motor drive vertically on a flat vertical surface by using bolts or screws. Other
directions are not allowed.
2. The AC motor drive will generate heat during operation. Allow sufficient space around the unit
for heat dissipation.
3. 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.
4. When the 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.

Chapter 2 Installation and Wiring|VFD-S Series
2-2 Revision August 2008, SE09, SW V2.61
5. When installing multiple AC motor drives in the same cabinet, they should be adjacent in a row
with enough space. When installing one AC motor drive below another one, use a metal
separation barrier between the AC motor drives to prevent mutual heating. Refer to figure below
for details.
6. Prevent fiber particles, scraps of paper, saw dust, metal particles, etc. from adhering to the
heatsink.
