CAUTION
Indicates a hazard that may damage the equipment or installation.
NOTE
Provides helpful information.
1.1 Electrical safety - general warning
The voltages used in the starter 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 starter.
Specific warnings are given at the relevant places in this guide.
1.2 System Design and Safety of Personnel
The starter is intended as a component for professional incorporation into complete equipment or a system. If
installed incorrectly, the starter may present a safety hazard.
The starter uses high voltages and currents, carries 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 and maintenance
must be carried out by personnel who have the necessary training and experience. They must read this safety
information and this guide carefully.
None of the starter functions must be used to ensure safety of personnel, ie they must not be used for
safety-related functions.
Careful consideration must be given to the functions of the starter 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 starter
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.
The system designer is responsible for ensuring that the complete system is safe and designed correctly according to
the relevant safety standards.
1.3 Environmental limits
Instructions regarding transport, storage, installation and use of the starter must be complied with, including the
specified environmental limits. Starters must not be subjected to excessive physical force.
1.4 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 connections.
Within the European Union, all machinery in which this product is used must comply with the following directives:
2006/42/EC: Safety of machinery.
2014/35/EU: Low voltage directive
1.5 Motor
Ensure the motor is installed in accordance with the manufacturer’s recommendations. Ensure the motor shaft is not
exposed.
The values of the motor parameters set in the starter affect the protection of the motor. The default values in the
starter should not be relied upon. It is essential that the correct value is entered in Pr 1A
Motor Full Load Current
.
This affects the thermal protection of the motor.
