WARNING
Obey Rules to Avoid Risk of Death
● Always comply with local codes and requirements if disposal of failed components is
necessary.
● Always ensure the use of an even and flat truck bed to transport the VFD system. Before
unloading, be sure that the concrete pad is level for storage and permanent positioning.
● Always confirm proper tonnage ratings of cranes, cables, and hooks when lifting the VFD
system. Dropping the cabinet or lowering it too quickly could damage the unit.
● Never disconnect control power while medium voltage is energized. This could cause
severe system overheating and/or damage.
● Never store flammable material in, on, or near the drive enclosure. This includes
equipment drawings and manuals.
● Never use fork trucks to lift cabinets that are not equipped with lifting tubes. Be sure that
the fork truck tines fit the lifting tubes properly and are the appropriate length.
