A Note contains information, which helps to ensure correct operation of the product.
NOTE
Electrical safety - general warning
The voltages used in the drive can cause severe electrical 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.
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 voltages 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 and SECURE DISABLE functions of the drive do not isolate dangerous
voltages from the output of the drive or from any external option unit. The supply must
be disconnected by an approved electrical isolation device before gaining access to the
electrical connections.
With the sole exception of the SECURE DISABLE function, none of the drive
functions must be used to ensure safety of personnel, i.e. they must not be used
for safety-related functions.
Careful consideration must be given to the functions of the drive which might result in a
hazard, either through their intended behaviour or through incorrect operation due to a
fault. In any application where a malfunction of the drive or its control system could lead
to or allow damage, loss or injury, a risk analysis must be carried out, and where
necessary, further measures taken to reduce the risk - for example, an over-speed
protection device in case of failure of the speed control, or a fail-safe mechanical brake
in case of loss of motor braking.
The SECURE DISABLE function has been approved
EN954-1 category 3 for the prevention of unexpected starting of the drive. It may be
