1 Safety information
General
Some parts of Lenze / AC Tech controllers can be electrically live and some surfaces can be hot.
Non-authorized removal of the required cover, inappropriate use, and incorrect installation or
operation creates the risk of severe injury to personnel or damage to equipment.
All operations concerning transport, installation, and commissioning as well as maintenance must
be carried out by qualified, skilled personnel who are familiar with the installation, assembly,
commissioning, and operation of variable frequency drives and the application for which it is being
used.
Installation
Ensure proper handling and avoid excessive mechanical stress. Do not bend any components and
do not change any insulation distances during transport, handling, installation or maintenance.
Do not touch any electronic components or contacts. This drive contains electrostatically sensitive
components, which can easily be damaged by inappropriate handling. Static control precautions
must be adhered to during installation, testing, servicing and repairing of this drive and associated
options. Component damage may result if proper procedures are not followed.
This drive has been tested by Underwriters Laboratory (UL) and is an approved component in
compliance with UL508 Safety Standard.
This drive must be installed and configured in accordance with both national and international
standards. Local codes and regulations take precedence over recommendations provided in this and
other Lenze / AC Tech documentation.
The SMVector drive is considered a component for integration into a machine or process. It is
neither a machine nor a device ready for use in accordance with European directives (reference
machinery directive and electromagnetic compatibility directive). It is the responsibility of the end
user to ensure that the machine meets the applicable standards.
Electrical connection
When working on live drive controllers, applicable national safety regulations must be observed.
The electrical installation must be carried out according to the appropriate regulations (e.g.
cable cross-sections, fuses, protective earth [PE] connection). While this document does make
recommendations in regards to these items, national and local codes must be adhered to.
The documentation contains information about installation in compliance with EMC (shielding,
grounding, filters and cables). These notes must also be observed for CE-marked controllers.
The manufacturer of the system or machine is responsible for compliance with the required limit
values demanded by EMC legislation.
Application
The drive must not be used as a safety device for machines where there is a risk of personal injury
or material damage. Emergency Stops, over-speed protection, acceleration and deceleration limits,
etc must be made by other devices to ensure operation under all conditions.
The drive does feature many protection devices which are aimed at protecting the drive and the
driven equipment by generating a fault and shutting the drive and motor down by removing power.
Mains power variances can also result in shutdown of the drive. When the fault condition disappears
or is cleared, the drive can be configured to automatically restart, it is the responsibility of the user
and/or OEM and/or integrator to ensure that the drive is configured for safe operation.
