Safety Considerations
Safety Precautions
This product is intended for professional incorporation 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 are used to 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 instruction manual carefully.
Enclosure
This product is intended to be mounted in an enclosure that prevents access
except by trained and authorized personnel and 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 in 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 must be
provided where needed.
