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
