1.6 SAFETY INFORMATION
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 and/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.
1.6.1 EXPLOSION PROOF APPLICATIONS
Explosion proof motors that are not rated for inverter use lose their certification when
used for variable speed. Due to the many areas of liability that may be encountered
when dealing with these applications, the following statement of policy applies:
Lenze AC Tech Corporation inverter products are sold with no warranty of fitness for a
particular purpose or warranty of suitability for use with explosion proof motors. Lenze
AC Tech Corporation accepts no responsibility for any direct, incidental or consequential
loss, cost or damage that may arise through the use of AC inverter products in these
applications. The purchaser expressly agrees to assume all risk of any loss, cost or
damage that may arise from such application.

WARNING!
This product can cause a d.c. current in the protective earthing (PE) conductor.
Where a residual current-operated (RCD) or monitoring (RCM) device is used
for protection in case of direct or indirect contact, only an RCD or RCM Type B is
allowed on the supply side of this product.
WARNING!
Leakage Current may exceed 3.5mA AC. The minimum size of the protective earth
(PE) conductor shall comply with local safety regulations for high leakage current
equipment.
DANGER! Hazard of Electric Shock
Capacitors retain charge for approximately 180 seconds after power is removed.
Allow at least 3 minutes for discharge of residual charge before touching the drive.
NOTE
Control terminals provide basic isolation (insulation per EN 61800-5-1, for up to
300V to ground). Protection against contact can only be ensured by additional
measures (e.g. supplemental insulation).
WARNING!
In a domestic environment this product may cause radio interference in which case
supplementary mitigation measures may be required.
