Specifi c Product Precautions 2
Be sure to read this before handling. For Safety Instructions and Electric Actuator
Precautions, refer to "Handling Precautions for SMC Products" and the Operation
Manual on the SMC website, http://www.smc.eu
Mounting
Warning
1. Install the controller 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. Do not mount the controller and its peripheral
devices on the same base together with a large-
sized electromagnetic contactor or no-fuse breaker
that generate vibration. Mount them on different
base plates, or keep the controller and its peripheral
devices away from such vibration supplies.
4. Install the controller 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.
5. Take measure so that the operating temperature of
the controller and its peripheral devices are within
the range of the specifications. Also, the controller
should be installed with 50 mm or larger spaces
between each side of it and the other structures or
components.
Otherwise, it may cause the controller and its peripheral
devices to fail and can result in a fire.
Power Supply
Warning
1. Use a power supply with low noise between lines
and between power and ground.
In cases where noise is high, use an isolation transformer.
2. Take appropriate measures to prevent surges from
lightning. Ground the surge absorber for lightning
separately from the grounding of the controller and
its peripheral devices.
Grounding
Warning
1. Make sure the product is grounded to ensure the
noise tolerance of the controller.
2. Use a dedicated grounding.
Use a D-class grounding (ground resistance 100 Ω or less).
3. The grounding point should be as close as possible
to the controller, and the ground wires as short as
possible.
4. In the unlikely event that malfunction is caused by
the ground, it may be disconnected.

Wiring
Warning
1. Do not apply any excessive force to cables by
repeated bending, tensioning or placing a heavy
object on the cables.
It may cause an electric shock, fire, or breaking of wire.
2. Connect wires and cables correctly.
Incorrect wiring could break the controller or its peripheral
devices depending on the seriousness.
3. Do not connect wires while the power is supplied.
It can break the controller or its peripheral devices could be
damaged to cause a malfunction.
4. Do not carry the product by holding its cables.
It may cause an injury or damage to the product.
5. Do not connect power or high voltage cables in the
same wiring path as the unit.
The product can malfunction due to noise and surge voltage
interference in the signal line from the power and high voltage
cables.
Separate the wiring of the controller and its peripheral device
from that of power and high voltage cables.
6. Verify wiring insulation.
Insulation failure (interference with other circuits, poor
insulation between terminals, etc.) could introduce excessive
voltage or current to the controller or its peripheral devices and
damage them.
Maintenance
Warning
1. Perform maintenance checks periodically.
Confirm wiring and screws are not loose. Loose screws or
wires may cause unexpected malfunction.
2. Conduct an appropriate functional inspection and
test after completed maintenance.
In case of any abnormalities (if the actuator does not move or
the equipment does not operate properly, etc.), stop the
operation of the system. Otherwise, unexpected malfunction
may occur and safety cannot be assured. Conduct a test of the
emergency stop to confirm the safety of the equipment.
3. Do not disassemble, modify or repair the controller
or its peripheral devices.
4. Do not put anything conductive or flammable inside
the controller.
Otherwise, fire can result.
5. Do not conduct an insulation resistance test or
insulation withstand voltage test.
6. Reserve sufficient space for maintenance.
Design the system so that it allows required space for maintenance.
