Specific warnings are given at the relevant places in this User Guide.
2.3

System design and safety of personnel

The drive is intended as a component for professional incorporation into
complete equipment or a system. If installed incorrectly, the drive may
present a safety hazard. The drive uses high voltage and currents, carries a
high level of 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 User Guide
carefully.
The STOP function of the drive does not remove dangerous voltages from the
output of the drive or from any external option unit.
Careful consideration must be given to the functions of the drive which might
result in a hazard, either through their intended functions or through incorrect
operation due to a fault.
In any application where a malfunction of the drive could lead to damage, loss
or injury, a risk analysis must be carried out, and where necessary, further
measures taken to reduce the risk.
