19. Controller and its peripheral devices /Specific product precautions
19.1 Design and selection
Warning
(1) Be sure to apply the specified voltage.
Otherwise, a malfunction and breakage of the controller may be caused.
If the applied voltage is lower than the specified, it is possible that the load cannot be moved due to an
internal voltage drop. Please check the operating voltage before use.
(2) Do not operate beyond the specifications.
It may cause a fire; malfunction or electric actuator damage can result. Please check the specifications
before use.
(3) Install an emergency stop circuit.
Please install an emergency stop outside of the enclosure so that it can stop the system operation
immediately and intercept the power supply.
(4) In order to prevent danger and damage due to the breakdown and the malfunction of this
product, which may occur at a certain probability, a backup system should be established
previously by giving a multiple-layered structure or a fail-safe design to the equipment, etc.
(5) If a fire or danger against the personnel is expected due to an abnormal heat generation, ignition,
smoking of the product, etc., cut off the power supply for this product and the system
immediately.
19.2 Handling
Warning
(1) The inside of the controller and its connector should not be touched.
It may cause an electric shock or damage to the controller.
(2) Do not perform the operation or setting of this equipment with wet hands.
It may cause an electric shock.
(3) Product with damage or the one lacking of any components should not be used.
It may cause an electric shock, fire, or injury.
(4) Use only the specified combination between the controller and electric actuator.
It may cause damage to the controller or the
electric actuator.
(5) Be careful not to be caught or hit by the work piece while the electric actuator is moving.
It may cause an injury.
(6) Do not connect the power supply or power on the product before confirming the area where the
work moves is safe.
The movement of the work may cause accident.
(7)
Do not touch the product when it is energized and for some time after power has been
disconnected, as it is very hot.
It may lead to a burn due to the high temperature.
(8)
Check the voltage using a tester for more than 5 minute after power-off in case of installation,
wiring and maintenance.
There is a possibility of getting electric shock, fire and injury.
(9) Do not use in an area where dust, powder dust, water or oil is in the air.
It will cause failure or malfunction.
(10) Do not use in an area where a magnetic field is generated.
It will cause failure or malfunction.
(11) Do not
install in the environment of flammable gas, corrosive gas and explosive gas.
It could lead to fire, explosion and corrosion.
(12) Do not apply radiant heat from a large heat source such as direct sunlight or heat treatment
furnace.
It will cause failure of the controller or its peripheral devices.
