• Do not hold the product by the cables or motor shaft while transporting it.
Failure to observe this caution may result in injury or malfunction.
• Do not place any load exceeding the limit specified on the packing box.
Failure to observe this caution may result in injury or malfunction.
• If disinfectants or insecticides must be used to treat packing materials such as
wooden frames, pallets, or plywood, the packing materials must be treated before
the product is packaged, and methods other than fumigation must be used.
Example: Heat treatment, where materials are kiln-dried to a core temperature of
56 °C for 30 minutes or more.
If the electronic products, which include stand-alone products and products installed
in machines, are packed with fumigated wooden materials, the electrical compo-
nents may be greatly damaged by the gases or fumes resulting from the fumigation
process. In particular, disinfectants containing halogen, which includes chlorine, flu-
orine, bromine, or iodine can contribute to the erosion of the capacitors.
• If the motor has been in storage for a long time, contact your Yaskawa representa-
tive.
• Use the eyebolt of the motor only to transport the motor. Do not use it to transport
other machines.
