System design
The Drive is intended as a component for professional incorporation into
complete equipment or systems. If installed incorrectly the Drive may
present a safety hazard. The Drive uses high voltages and currents, carries
a high level of stored electrical energy, and is used to control mechanical
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.
To ensure mechanical safety, additional safety devices such as
electro-mechanical interlocks may be required. The Drive must not be used
