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 Control 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 Control User Guide carefully.
The STOP 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.
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 behavior 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.
1.4

Environmental limits

Instructions in the Power Installation 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

Access

Drive access must be restricted to authorized personnel only. Safety
regulations which apply at the place of use must be complied with.

Fire protection

The drive enclosure is not classified as a fire enclosure. A separate fire
enclosure must be provided. For further information, refer to the relevant
Power Installation Guide.
1.7

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 ground (earth) connections.
The Power Installation 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:
2006/42/EC Safety of machinery.
2014/30/EU: Electromagnetic Compatibility Directive.
1.8 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 Pr 00.006 motor rated
current. This affects the thermal protection of the motor.
1.9

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.
1.10

Electrical installation

1.10.1 Electric shock risk
The voltages present in the following locations can cause severe electric
shock and may be lethal:
AC supply cables and connections
Output cables and connections
Many internal parts of the drive, and external option units
Unless otherwise indicated, control terminals are single insulated and
must not be touched.
1.10.2 Stored charge
The drive contains capacitors that remain charged to a potentially lethal
voltage after the AC supply has been disconnected. If the drive has been
energized, the AC supply must be isolated at least ten minutes before
work may continue.
1.11

Hazard

1.11.1 Falling hazard
The drive presents a falling or toppling hazard. This can cause injury to
personnel and therefore should be handled with care.
