Issue Number: 2
1 Safety information
1.1 Warnings, Cautions and Notes
1.2 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 guide.
1.3 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 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/start-up and maintenance must be carried out by personnel who have the necessary
training and experience. They must read this safety information and this Guide carefully.
The STOP 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.
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.
The system designer is responsible for ensuring that the complete system is safe and designed
correctly according to the relevant safety standards.
1.4 Environmental limits
Instructions in this guide regarding transport, storage, installation and use of the drive must be
complied with, including the specified environmental limits. Drives must not be subjected to
excessive physical force.
A Warning contains information which is essential for avoiding a safety hazard.
A Caution contains information which is necessary for avoiding a risk of damage to the
product or other equipment.
A Note contains information, which helps to ensure correct operation of the product.
