1.5 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.
The safety information given in these Operating Instructions is defined herein.

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.
The SCF 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.
Integral solid state protection does not provide branch circuit protection. Branch circuit protection
must be provided in accordance with the National Electrical Code and any additional local codes. The
use of fuses or circuit breakers is the only approved means for branch circuit protection.
