NOTE
1.2
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.
1.3
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, i.e. 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.
1.4
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.
1.5
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 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.
2004/108/EC: Electromagnetic Compatibility.
1.6
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.
1.7
Adjusting parameters
Some parameters have a profound effect on the operation of the starter. 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.
