CAUTION
NOTE
A Note contains information which helps to ensure correct operation of
the product.
1.2
Electrical safety - general warning
The voltages used in the drive can cause severe electrical shock and/or
burns, and could be lethal. Extreme care is necessary at all times when
working with or adjacent to the drive.
Specific warnings are given at the relevant places in this User Guide.
1.3
System design and safety of
personnel
The drive is intended as a component for professional incorporation into
complete equipment or a system. If installed incorrectly, the drive may
present a safety hazard.
The drive uses high voltages and currents, carries a high level of stored
electrical energy, and is used to control equipment which can cause
injury.
Close attention is required to the electrical installation and the system
design to avoid hazards either in normal operation or in the event of
equipment malfunction. System design, installation, commissioning/
start-up and maintenance must be carried out by personnel who have
the necessary training and experience. They must read this safety
information and this User Guide carefully.
The STOP and SAFE TORQUE OFF (SECURE DISABLE) function
functions of the drive do not isolate dangerous voltages from the output
of the drive or from any external option unit. The supply must be
disconnected by an approved electrical isolation device before gaining
access to the electrical connections.
With the sole exception of the SAFE TORQUE OFF (SECURE
DISABLE) function, none of the drive functions must be used to
ensure safety of personnel, i.e. they must not be used for safety-
related functions.
Careful consideration must be given to the functions of the drive which
might result in a hazard, either through their intended behaviour or
through incorrect operation due to a fault. In any application where a
malfunction of the drive or its control system could lead to or allow
damage, loss or injury, a risk analysis must be carried out, and where
necessary, further measures taken to reduce the risk - for example, an
over-speed protection device in case of failure of the speed control, or a
fail-safe mechanical brake in case of loss of motor braking.
The SAFE TORQUE OFF (SECURE DISABLE) function has been
1
approved
as meeting the requirements of EN954-1 category 3 for the
prevention of unexpected starting of the drive. It may be used in a
safety-related application. The system designer is responsible for
ensuring that the complete system is safe and designed correctly
according to the relevant safety standards.

Environmental limits
Instructions in this User Guide regarding transport, storage, installation
and use of the drive must be complied with, including the specified
environmental limits. Drives must not be subjected to excessive physical
force.
1.5
Compliance with regulations
The installer is responsible for complying with all relevant regulations,
such as national wiring regulations, accident prevention regulations and
electromagnetic compatibility (EMC) regulations. Particular attention
must be given to the cross-sectional areas of conductors, the selection
of fuses or other protection, and protective earth (ground) connections.
This User Guide contains instruction for achieving compliance with
specific EMC standards.
Within the European Union, all machinery in which this product is used
must comply with the following directives:
98/37/EC: Safety of machinery.
89/336/EEC: Electromagnetic Compatibility.
1.6
Motor
Ensure the motor is installed in accordance with the manufacturer's
recommendations. Ensure the motor shaft is not exposed.
Standard squirrel cage induction motors are designed for single speed
operation. If it is intended to use the capability of the drive to run a motor
at speeds above its designed maximum, it is strongly recommended that
the manufacturer is consulted first.
Low speeds may cause the motor to overheat because the cooling fan
becomes less effective. The motor should be installed with a protection
thermistor. If necessary, an electric forced vent fan should be used.
The values of the motor parameters set in the drive affect the protection
of the motor. The default values in the drive should not be relied upon.
It is essential that the correct value is entered in parameter 0.46 motor
rated current. This affects the thermal protection of the motor.
1.7
Adjusting parameters
Some parameters have a profound effect on the operation of the drive.
They must not be altered without careful consideration of the impact on
the controlled system. Measures must be taken to prevent unwanted
changes due to error or tampering.
