The drive is an electronic motor controller intended for:
Regulation of motor speed in response to system feedback or to remote commands from external controllers. A power drive
system consists of the AC drive, the motor, and equipment driven by the motor.
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 com-
pliance with the conditions specified in Ambient Conditions.
NOTICE

2 Safety
2.1 Safety Symbols
The following symbols are used in this manual:
DANGER
Indicates a hazardous situation which, if not avoided, will result in death or serious injury.
WARNING
Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION
Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.
NOTICE
Indicates information considered important, but not hazard-related (for example, messages relating to property damage).
2.2 Qualified Personnel
Correct and reliable transport, storage, installation, operation, and maintenance are required for the trouble-free and safe operation
of the drive. Only qualified personnel are allowed to install and operate this equipment.
Qualified personnel are defined as trained staff, who are authorized to install, commission, and maintain equipment, systems, and
circuits in accordance with pertinent laws and regulations. Also, the qualified personnel must be familiar with the instructions and
safety measures described in this manual.
2.3 Safety Precautions
WARNING
HAZARDOUS VOLTAGE
AC drives contain hazardous voltage when connected to the AC mains or connected on the DC terminals. Failure to perform
installation, start-up, and maintenance by skilled personnel can result in death or serious injury.
Only skilled personnel must perform installation, start-up, and maintenance.
WARNING
UNINTENDED START
When the drive is connected to the AC mains, DC supply, or load sharing, the motor may start at any time, causing risk of death,
serious injury, and equipment or property damage. The motor may start by activation of an external switch, a fieldbus command,
an input reference signal from the LCP or LOP, via remote operation using MCT 10 Set-up software, or after a cleared fault condi-
tion.
Press [Off] on the LCP before programming parameters.
Disconnect the drive from the mains whenever personal safety considerations make it necessary to avoid unintended motor
start.
Check that the drive, motor, and any driven equipment are in operational readiness.

WARNING
DISCHARGE TIME
The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be
present even when the warning indicator lights are off.
Failure to wait the specified time after power has been removed before performing service or repair work could result in death or
serious injury.
Stop the motor.
Disconnect AC mains, permanent magnet type motors, and remote DC-link supplies, including battery back-ups, UPS, and
DC-link connections to other drives.
Wait for the capacitors to discharge fully. The minimum waiting time is specified in the table Discharge time and is also visible
on the nameplate on top of the drive.
Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors
are fully discharged.

WARNING
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the drive properly can result in death or serious injury.
Ensure that the minimum size of the ground conductor complies with the local safety regulations for high touch current
equipment.
WARNING
ROTATING SHAFTS
Contact with rotating shafts and electrical equipment can result in death or serious injury.
Ensure that only trained and qualified personnel perform installation, start-up, and maintenance.
Ensure that electrical work conforms to national and local electrical codes.
Follow the procedures in this guide.
WARNING
UNINTENDED MOTOR ROTATION WINDMILLING
Unintended rotation of permanent magnet motors creates voltage and can charge the unit, resulting in death, serious injury, or
equipment damage.
Ensure that permanent magnet motors are blocked to prevent unintended rotation.
