3 iC2-Micro Frequency Converters
3.1 Intended Use
The drive is an electronic motor controller intended for:
l Regulation of motor speed in response to system feedback or to remote commands from external controllers. A power drive system
consists of the drive and the motor.
l System and motor status surveillance.
The drive can also be used for motor overload protection.
Depending on the configuration, the drive can be used in standalone applications or form part of a larger appliance or installation.
The drive is allowed for use in residential, industrial, and commercial environments in accordance with local laws and standards.
NOTICE
In a residential environment, this product can cause radio interference, in which case supplementary mitigation measures can be
required.
Foreseeable misuse
Do not use the drive in applications which are non-compliant with specified operating conditions and environments. Ensure compliance
with the conditions specified in chapter Specifications.
