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 Installation (continued)
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.
