1. Use the specified voltage.
If the applied voltage is higher than the specified voltage,
malfunction and damage to the driver may result. If the applied
voltage is lower than the specified voltage, there is a possibility
that the load cannot be moved due to internal voltage drop. Check
the operating voltage prior to start. Also, confirm that the operating
voltage does not drop below the specified voltage during operation.
2. Do not use the products outside the specifications.
Otherwise, fire, malfunction or damage to the driver/actuator can
result. Check the specifications prior to use.
3. Install an emergency stop circuit.
Install an emergency stop outside the enclosure in easy reach to
the operator so that the operator can stop the system operation
immediately and intercept the power supply.
4. To prevent danger and damage due to a breakdown or
malfunction of these products, which may occur at a
certain probability, a backup system should be arranged
in advance by using a multiple-layered structure or by
making a fail-safe equipment design, etc.
5. If there is a risk of fire or personal injury due to
abnormal heat generation, sparking, smoke generated
by the product, etc., cut off the power supply from this
product and the system immediately.
6. The parameters of the driver are set to initial values.
Please change parameters according to the specifications
of the customer’s equipment before use.
Refer to the operation manual for details of parameters.
1. Never touch the inside of the driver and its peripheral
devices.
Otherwise, electric shock or failure can result.
2. Do not operate or set up this equipment with wet hands.
Otherwise, electric shock can result.
3. Do not use a product that is damaged or missing any
components.
Electric shock, fire or injury can result.
4. Use only the specified combination between the
electric actuator and driver.
Otherwise, it may cause damage to the driver or to the other
equipment.
5. Be careful not to touch, get caught or hit by the
workpiece while the actuator is moving.
An injury can result.
6. Do not connect the power supply or power up the
product until it is confirmed that the workpiece can be
moved safely within the area that can be reached by
the workpiece.
Otherwise, the movement of the workpiece may cause an accident.
7. Do not touch the product when it is energized and for
some time after the power has been disconnected, as
it is very hot.
Otherwise, it may cause burns due to the high temperature.
8. Check the voltage using a tester at least 5 minutes after
power-off when performing installation, wiring and
maintenance.
Otherwise, electric shock, fire or injury can result.
9. Static electricity may cause a malfunction or damage
the driver. Do not touch the driver while power is
supplied to it.
Take sufficient safety measures to eliminate static electricity when
it is necessary to touch the driver for maintenance.
10. Do not use the products in an area where they could be
exposed to dust, metallic powder, machining chips or
splashes of water, oil or chemicals.
Otherwise, a failure or malfunction can result.
11. Do not use the products in a magnetic field.
Otherwise, a malfunction or failure can result.
12. Do not use the products in an environment where
flammable, explosive or corrosive gases, liquids or
other substances are present.
Otherwise, fire, explosion or corrosion can result.
13. Avoid heat radiation from strong heat sources, such as
direct sunlight or a hot furnace.
Otherwise, it will cause a failure to the driver or its peripheral
devices.
14. Do not use the products in an environment with cyclic
temperature changes.
Otherwise, it will cause a failure to the driver or its peripheral
devices.
15. Do not use the products in an environment where surges
are generated.
Devices (solenoid type lifters, high frequency induction furnaces,
motors, etc.) that generate a large amount of surge around the
product may lead to deterioration or damage to the internal circuits
of the products. Avoid supplies of surge generation and crossed
lines.
16. Do not install these products in a place subject to
vibration and impact.
Otherwise, a malfunction or failure can result.
17. When a surge generating load such as a relay or
solenoid valve is directly driven, use a product that
incorporates a surge absorption element.
Mounting
1. Install the driver and its peripheral devices on fireproof
material.
Direct installation on or near flammable material may cause fire.
2. Do not install these products in a place subject to
vibration and impact.
Otherwise, a malfunction or failure can result.
3. The driver should be mounted on a vertical wall in a
vertical direction.
Also, do not cover the driver’s suction/exhaust ports.
4. Install the driver and its peripheral devices on a flat
surface.
If the mounting surface is not flat or uneven, excessive force may
be applied to the housing and other parts resulting in a
malfunction.
