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.
1.6.2 EN 61800-5-1 COMPLIANCE
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

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.
