YASKAWA UAK series User Manual page 7

• Provide an appropriate braking device on the machine side to ensure safety. A holding brake for a
servomotor with brake is not a braking device for ensuring safety.
Failure to observe this warning may result in injury.
• Do not come close to the machine immediately after resetting momentary power loss to avoid an
unexpected restart. Take appropriate measures to ensure safety against an unexpected restart.
Failure to observe this warning may result in injury.
• Refer to the SigmaWin for Σ-V-SD (MT) Operation Manual before you make adjustments.
Failure to observe this warning may result in injury or damage to the product.
• Connect the ground terminal to electrical codes (ground resistance: 100 Ω or less for a power
regeneration converter and a SERVOPACK with a 200 V power supply. 10 Ω or less for a power
regeneration converter and a SERVOPACK with a 400 V power supply).
Improper grounding may result in electric shock or fire.
• Installation, disassembly, or repair must be performed only by authorized personnel.
Failure to observe this warning may result in electric shock or injury.
• The person who designs a system using the Hard Wire Base Block function must have full knowl-
edge of the related safety standards and full understanding of the instructions in this manual.
Failure to observe this warning may result in injury or damage to the product.
Storage and Transportation
• Do not store or install the product in the following places.
• Locations subject to direct sunlight.
• Locations subject to temperatures outside the range specified in the storage/installation temperature condi-
tions.
• Locations subject to humidity outside the range specified in the storage/installation humidity conditions.
• Locations subject to condensation as the result of extreme changes in temperature.
• Locations subject to corrosive or flammable gases.
• Locations subject to dust, salts, or iron dust.
• Locations subject to exposure to water, oil, or chemicals.
• Locations subject to shock or vibration.
Failure to observe this caution may result in fire, electric shock, or damage to the product.
• Do not hold the motors by the cable, motor shaft, or encoder while transporting it.
Failure to observe this caution may result in injury or malfunction.
• Do not hold the power regeneration converters and SERVOPACKs by the front cover or terminal
cover while moving them.
Failure to observe this caution may result in damage to the covers or in a greater possibility of the products
being dropped and damaged.
• 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, pal-
lets, or plywood, the packing materials must be treated before the product is packaged, and meth-
ods other than fumigation must be used.
Example: Heat treatment, where materials are kiln-dried to a core temperature of 56°C for 30 min-
utes or more.
If the electronic products, which include stand-alone products and products installed in machines, are packed
with fumigated wooden materials, the electrical components may be greatly damaged by the gases or fumes
resulting from the fumigation process. In particular, disinfectants containing halogen, which includes chlo-
rine, fluorine, bromine, or iodine can contribute to the erosion of the capacitors.
