Chapter 1
Introduction
Congratulations on your purchase of a VLT®Adjustable Frequency Drive. The VLT®
MICRO is a high-performance / low noise general-purpose drive, manufactured using
the highest quality components and incorporating the latest micro-processor technology
and control algorithms.
The purpose of this chapter is to provide specific yet simple information to unpack,
install, and operate the drive. This chapter contains information on the following:
• Getting Started
• Unpacking, Inspection, and Storage
• Nameplate Information
• Identification of Parts
Getting Started
This manual will help in the installation, parameter setting, troubleshooting, and daily
maintenance of the AC drive. To guarantee safe operation of the equipment, read the
following safety guidelines before connecting the Adjustable Frequency Drive to AC
Power.
The VLT Adjustable Frequency Drive (AFD) contains dangerous voltages
when connected to line voltage. After disconnecting from the line wait at
least one minute before touching any electrical components. Also make
sure that other voltage inputs have been disconnected, such as external 24
VDC, load-sharing (linkage of DC intermediate circuit), as well as the motor
connection for kinetic back-up. Only a competent electrician should carry
out the electrical installation. Improper installation of the motor or the AFD
may cause equipment failure, serious injury or death. Follow this manual,
National Electrical Codes (NEC®) and local safety codes.
Electrostatic Precaution; Electrostatic discharge (ESD). Many electronic
components are sensitive to static electricity. Voltages so low that they
cannot be felt, seen or heard, can reduce the life, affect performance, or
completely destroy sensitive electronic components. When performing
service, proper ESD equipment should be used to prevent possible damage
from occurring.
It is the responsibility of the user or the person installing the AFD to provide
proper grounding, as well as motor overload and branch circuit protection
according to the National Electrical Code (NEC®) and local codes.

Receiving,Transporting, Inspecting, and Storage
This VLT®MICRO Adjustable Frequency Drive has gone through rigorous quality control
tests at the factory before shipment. After receiving and before transporting the drive,
check for the following.
Receipt
After receiving the AC drive, inspect the unit to insure it was not damaged during
shipment.
Transportation
Climatic condition : Class 2K3
Inspection
• After unpacking the unit, make sure that the package includes a drive unit and the
Instruction Manual.
• Make sure that the part number indicated on the nameplate and packing carton
corresponds with the part number of your order.
Storage
The AFD should be kept in the shipping carton before installation. In order to retain the
warranty coverage, the drive should be stored properly. Some storage
recommendations are:
• Store in a clean, dry place
• Store within an ambient temperature range of -20°C to +65°C
• If possible, store in an air-conditioned evironment where the relative humidity is less
than 95%, non-condensing.
• Do not store the unit in places where it could be exposed to corrosive gases.
• Do not store the unit on an unstable surface where it could be damaged by falling to
the floor.

Installation and Wiring
Chapter 2 provides the information needed to properly install and wire the AC motor
drive. Make sure that the AC drive is wired according to the instructions contained in
this chapter. The instructions should be read and understood before the actual
installation begins. This chapter contains the following information:
• Installation Requirements
• Wiring
Installation Requirements
Install the drive vertically to provide proper ventilation. Adequate space is required
between the drive and a wall or other equipment. The figure below shows the minimum
space needed.
The AC motor drive should be installed in an environment that is:
• protected from rain or moisture
• protected from direct sunlight
• protected from corrosive gases or liquids
• free from airborne dust or metallic particles
• free from vibration
• free from magnetic noise
• Climate condition : Class 3K3 (temperature between -10°C to 50°C, Operation
above 40°C requires good ventilation to avoid over-heating.)
