RNING
The installation must be suitable and it must be performed only by an experienced technician.
There is a risk of electrical shock or injury.
Before connecting the machine and starting operation, make sure that an emergency stop pro-
cedure has been provided and is working correctly.
There is a risk of injury.
Do not approach the machine after 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 when operation restarts.
There is a risk of injury.
Do not touch anything inside the Machine Controller.
There is a risk of electrical shock.
Do not remove the front cover, cables, connector, or options while power is being supplied.
There is a risk of electrical shock, malfunction, or damage.
Do not damage, pull on, apply excessive force to, place heavy objects on, or pinch the cables.
There is a risk of electrical shock, operational failure of the Machine Controller, or burning.
Do not attempt to modify the Machine Controller in any way.
There is a risk of injury or device damage.

UTION
Do not store the Machine Controller in any of the following locations.
•
Locations that are subject to direct sunlight
•
Locations that are subject to ambient temperatures that exceed the storage conditions
•
Locations that are subject to ambient humidity that exceeds the storage conditions
•
Locations that are subject to rapid temperature changes and condensation
•
Locations that are subject to corrosive or inflammable gas
•
Locations that are subject to excessive dust, dirt, salt, or metallic powder
•
Locations that are subject to water, oil, or chemicals
•
Locations that are subject to vibration or shock
There is a risk of fire, electrical shock, or device damage.
Hold onto the main body of the Machine Controller when transporting it.
Holding the cables or connectors may damage them or result in injury.
Do not overload the Machine Controller during transportation. (Follow all instructions.)
There is a risk of injury or an accident.
Never subject the Machine Controller to an atmosphere containing halogen (fluorine, chlorine,
bromine, or iodine) during transportation.
There is a risk of malfunction or damage.
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 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 chlorine, fluorine, bromine, or iodine can contribute to the erosion of the
capacitors.
