Safety Information
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.
Operation
Systems including controllers must be equipped with additional monitoring and protection devices according to the
corresponding standards (e.g. technical equipment, regulations for prevention of accidents, etc.). The controller may be
adapted to your application as described in this documentation.
DANGER!
• After the controller has been disconnected from the supply voltage, live components and power connection
must not be touched immediately, since capacitors could be charged. Please observe the corresponding notes
on the controller.
• Close all protective covers and doors prior to and during operation.
• Do not cycle input power to the controller more than once every two minutes.
• For SMVector models that are equipped with a Disconnect Switch (11th character in model number is L or M),
the Disconnect Switch is intended as a motor service disconnect and does not provide branch circuit protection
to the inverter or motor. When servicing the motor, it is necessary to wait 3 minutes after turning this switch
to the off position before working on motor power wiring as the inverter stores electrical power. To service the
inverter, it is necessary to remove mains ahead of the drive and wait 3 minutes.
