Warning
1. Use the specified voltage.
If the applied voltage is higher than the specified voltage,
malfunction and damage to the controller 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.
2. Do not use the products outside the specifications.
Otherwise, fire, malfunction or damage to the product 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, 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 gener-
ated by the product, etc., cut off the power supply
from this product and the system immediately.

Warning
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 controller. Do not touch the controller while
power is supplied to it.
Take sufficient safety measures to eliminate static electricity
when it is necessary to touch the controller for maintenance.
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.
Do not use the products in a magnetic field.
Otherwise, a malfunction or failure can result.
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.
Avoid heat radiation from strong heat sources, such
as direct sunlight or a hot furnace.
Otherwise, it will cause a failure to the controller or its periph-
eral devices.
Do not use the products in an environment with
cyclic temperature changes.
Otherwise, it will cause a failure to the controller or its periph-
eral devices.
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.
Do not install the products in a place subject to
vibration and impact.
Otherwise, a malfunction or failure can result.
When a surge generating load such as a relay or
solenoid valve is directly driven, use a product that
incorporates a surge absorbing element.
The power supplies should be separated between
the controller power and the I/O signal power, and
both power supplies must not be of “inrush current
limited” type.
If the power supply is of “inrush current limited” type, a voltage
drop may occur during the acceleration or deceleration of the
actuator.

Warning
1. Never touch the inside of the controller 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 controller.
It may cause damage to the actuator or to the controller.
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 energised and
for some time after the power has been disconnect-
ed, as it is very hot.
Otherwise, it may cause burns due to the high temperature.
