⑧ Products with damage or those missing any components should not be used.
An electric shock, fire, or injury may result.
⑨ Be careful not to be caught or hit by the workpiece while the electric actuator is moving.
It may cause an injury.
⑩ Do not connect the power supply to the product before confirming the area to
which the work- piece moves are safe.
The movement of the workpiece may cause an accident.
⑪ Before installation, wiring, and maintenance, the voltage should be checked with a
tester 5 minutes after the power supply has been turned off.
Otherwise, an electric shock, fire, or injury may result.
⑫ Do not use the product in an area where dust, powder, water, chemicals, or oil is in
the air.
It will cause failure or malfunction.
⑬ Do not use the product in an area where a magnetic field is generated.
It will cause failure or malfunction.
⑭ Do not install the product in an environment containing flammable gas, explosive gas,
or corrosive gas.
It could lead to fire, explosion, and corrosion.
⑮ Radiant heat from strong heat sources, such as a furnace, direct sunlight, etc., should
not be applied to the product.
It will cause failure of the electric actuator or its peripheral devices.
⑯ Do not use the product in an environment subject to a temperature cycle.
It will cause failure of the electric actuator or its peripheral devices.
⑰ Do not use the product in a place where electrical surges are generated.
When there are units that generate a large amount of surge around the product (e.g. solenoid type
lifters, high-frequency in- duction furnaces, motors, etc.), this may cause deterioration or damage to
the product's internal circuit. Avoid sources of surge generation and crossed lines.
⑱ Do not install the product in an environment under the effect of vibrations and impacts.
It will cause failure or malfunction.
⑲ When a surge-generating load, such as a relay or solenoid valve, is driven directly, use a
product that incorporates a surge protection device.
⑳ In the case of an actuator that has a servo motor (24 VDC), the motor phase detection
step is conducted by inputting the servo ON signal just after the controller power is
turned on. The motor phase detection step moves the table/rod by a distance of one
screw-lead maximum.
(The motor rotates in the reverse direction if the table/rod hits an obstacle such as an end stop
damper). Take the motor phase detection step into consideration when installing and operating this
actuator.
