Safety Precautions
The following precautions are for checking products on delivery, storage, transportation, installation, wiring, operation,
inspection, and disposal. These precautions are important and must be observed.
General Precautions
Storage and Transportation
Before connecting the machine and starting operation, ensure that an emergency stop procedure has been
provided and is working correctly.
There is a risk of injury.
Do not touch anything inside the Machine Controller.
There is a risk of electrical shock.
Always keep the front cover attached when power is being supplied.
There is a risk of electrical shock.
Observe all procedures and precautions given in this manual for trial operation.
Operating mistakes while the servomotor and machine are connected may damage the machine or even cause acci-
dents resulting in injury or death.
Do not remove the front cover, cables, connectors, or options while power is being supplied.
There is a risk of electrical shock.
Do not damage, pull on, apply excessive force to, place heavy objects on, or pinch cables.
There is a risk of electrical shock, operational failure or burning of the Machine Controller.
Do not attempt to modify the Machine Controller in any way.
There is a risk of injury or device damage.
Do not approach the machine when there is a momentary interruption to the power supply. When power is
restored, the Machine Controller and the device connected to it may start operation suddenly. Provide
safety measures in advance to ensure human safety in the event that operation restarts suddenly.
There is a risk of injury.
Do not allow installation, disassembly, or repairs to be performed by anyone other than specified person-
nel.
There is a risk of electrical shock or injury.
Do not store or install the Machine Controller in the following locations.
There is a risk of fire, electrical shock, or device damage.
• Direct sunlight
• Ambient temperature exceeds the storage or operating conditions
• Ambient humidity exceeds the storage or operating conditions
• Rapid changes in temperature or locations subject to condensation
• Corrosive or flammable gas
• Excessive dust, dirt, salt, or metallic powder
• Water, oil, or chemicals
• Vibration or shock
Do not overload the Machine Controller during transportation.
There is a risk of injury or an accident.
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 components may be greatly damaged by the gases or fumes resulting from
the fumigation process. In particular, disinfectants containing halogen, which includes chlorine, fluorine, bromine, or
iodine can contribute to the erosion of the capacitors.
