1.4

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 in the relevant places throughout this guide.
1.5

System design and safety of personnel

The STOP and SAFE TORQUE OFF 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 SAFE TORQUE OFF 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 behavior 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.
