2.2 Electrical safety – general warning
The voltages used in the Drive 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 the Drive.
Specific warnings are given at the relevant places in this User Guide.
The installation must comply with all relevant safety legislation in the
country of use.
The Drive contains capacitors that remain charged to a potentially lethal
voltage after the
AC
supply has been disconnected. If the Drive has been
energized, the
AC
supply must be isolated at least ten minutes before work
may continue.
2.3 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
in a safety-critical application without additional high-integrity protection
against hazards arising from a malfunction.
