They are all important notes for safety and must be followed in addition
to International Standards (ISO/IEC)*1), and other safety regulations.
*1) ISO 4414: Pneumatic fluid power - General rules relating to systems.
ISO 4413: Hydraulic fluid power - General rules relating to systems.
IEC 60204-1: Safety of machinery - Electrical equipment of machines.
(Part 1: General requirements)
ISO 10218-1: Robots and robotic devices - Safety requirements for
industrial robots - Part 1: Robots.
Refer to product catalogue, Operation Manual and Handling
Precautions for SMC Products for additional information.
Keep this manual in a safe place for future reference.
Caution
Caution indicates a hazard with a low level of risk which, if
not avoided, could result in minor or moderate injury.
Warning
Warning indicates a hazard with a medium level of risk
which, if not avoided, could result in death or serious injury.
Danger
Danger indicates a hazard with a high level of risk which, if
not avoided, will result in death or serious injury.
Warning
Always ensure compliance with relevant safety laws and
standards.
All work must be carried out in a safe manner by a qualified person in
compliance with applicable national regulations.
This product is class A equipment intended for use in an industrial
environment. There may be potential difficulties in ensuring
electromagnetic compatibility in other environments due to conducted
or radiated disturbances.
Caution
Ensure that the air supply system is filtered to 5 microns.

3 Installation
3.1 Installation Warning
Do not install the product unless the safety instructions have been read
and understood.
This product is pre-set at the factory and must not be dismantled by
the user. Contact your local SMC office for advice.
Ensure, when installing this product, that it is kept clear of power lines
to avoid noise interference.
Ensure that load surge protection is fitted when inductive loads are
present (i.e. solenoid, relay etc.).
3.2 Environment Warning
Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
Do not use in an explosive atmosphere.
Do not expose to direct sunlight. Use a suitable protective cover.
Do not install in a location subject to vibration or impact. Check the
product specifications.
Do not mount in a location exposed to radiant heat.
3.3 Piping Caution
Before piping make sure to clean up chips, cutting oil, dust etc.
When installing piping or fittings, ensure sealant material does not
enter inside the port. When using seal tape, leave 1 thread exposed
on the end of the pipe/fitting.
Tighten fittings to the specified tightening torque.
3.4 Lubrication Caution
Do not use a lubricator on the input side of this product. If lubrication
is required, place the lubricator on the ‘output’ side so that it does not
enter the product.
SMC products have been lubricated for life at manufacture, and do not
require lubrication in service.
If a lubricant is to be used in the system, refer to the catalogue for
details.
4 Wiring
Caution
Connect the cable to the connector on the main unit as shown in the
following diagram. Take precautions, as incorrect wiring will damage the
unit. Use a DC power supply capable of supplying the necessary power
requirements with minimal ripple.
The 3 m straight cable specified refers to the power supply cable. The
communication cable should be ordered separately.
