Safety Information
Persons supervising and performing the electrical installation or maintenance of a Drive
and/or an external Option Unit must be suitably qualified and competent in these duties.
They should be given the opportunity to study and if necessary to discuss this User Guide
before work is started.
The voltages present in the Drive and external Option Units are capable of inflicting a
severe electric shock and may be lethal. The Stop function of the Drive does not remove
dangerous voltages from the terminals of the Drive and external Option Unit. Mains
supplies should be removed before any servicing work is performed.
The installation instructions should be adhered to. Any questions or doubt should be
referred to the supplier of the equipment. It is the responsibility of the owner or user to
ensure that the installation of the Drive and external Option Unit, and the way in which
they are operated and maintained complies with the requirements of the Health and Safety
at Work Act in the United Kingdom and applicable legislation and regulations and codes of
practice in the UK or elsewhere.
The Drive software may incorporate an optional Auto-start facility. In order to prevent
the risk of injury to personnel working on or near the motor or its driven equipment and to
prevent potential damage to equipment, users and operators, all necessary precautions
must be taken if operating the Drive in this mode.
The Stop and Start inputs of the Drive should not be relied upon to ensure safety of
personnel. If a safety hazard could exist from unexpected starting of the Drive, an
interlock should be installed to prevent the motor being inadvertently started.
General information
The manufacturer accepts no liability for any consequences resulting from inappropriate,
negligent or incorrect installation or adjustment of the optional operating parameters of
the equipment or from mismatching the variable speed drive (Drive) with the motor.
