Safety Considerations
Safety Precautions
This product is intended for professional integration into a complete system. If you install the
product incorrectly, it may present a safety hazard. The product and system may use high
voltages and currents, carry a high level of stored electrical energy, or control mechanical
equipment that can cause injury.
You should give close attention to the electrical installation and 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. Read and follow this safety information and the instruction
manual carefully.
Enclosure
This product is intended to be mounted in an enclosure which prevents access except by
trained and authorized personnel, and which prevents the ingress of contamination. This
product is designed for use in an environment classified as pollution degree 2 in accordance
with IEC664-1. This means that only dry, non-conducting contamination is acceptable.
Setup, Commissioning and Maintenance
It is essential that you give careful consideration to changes to drive settings. Depending on
the application, a change could have an impact on safety. You must take appropriate
precautions against inadvertent changes or tampering. Restoring default parameters in certain
applications may cause unpredictable or hazardous operation.
Safety of Machinery
Within the European Union all machinery with which this product is used must comply with
Directive 89/392/EEC, Safety of Machinery.
The product has been designed and tested to a high standard, and failures are very unlikely.
However the level of integrity offered by the product’s control function – for example stop/
start, forward/reverse and maximum speed – is not sufficient for use in safety-critical
applications without additional independent channels of protection. All applications where
malfunction could cause injury or loss of life must be subject to a risk assessment, and further
protection provided where needed.
General warning
Failure to follow safe installation guidelines can cause death or serious injury. The voltages used in
this unit can cause severe electric shock and/or burns, and could be lethal. Extreme care is necessary
at all times when working with or adjacent to this equipment. The installation must comply with all
