Wiring (Fig 4)
CAUTION
Isolate both power and air supplies before removing/replacing
connector.
In the case of DIN connector and terminal block (with lamp and surge
voltage suppressor), the internal wiring is shown in Fig 4.
1. Loosen the top screw and remove the connector housing from the
terminal spades on the solenoid.
2. Remove the housing screw and insert a screwdriver into the slot
on the underside of the DIN cap and carefully remove the block.
3. Loosen the terminal screws on the block and insert the stripped
leads. Secure each lead by re-tightening the appropriate terminal
screw.
4. Tighten the housing grommet nut to secure the cable.
CAUTION
Pull connector out vertically, never at an angle.

Safety Instructions
These safety instructions are intended to prevent a hazardous situa-
tion and/or equipment damage. These instructions indicate the level
of potential hazard by label of “Caution”, “Warning” or “Danger”.
To ensure safety, be sure to observe ISO4414
(Note1)
, JIS B 8370
(Note2)
and other safety practices.
Note 1: ISO 4414: Pneumatic fluid power – Recommendations for the
application of equipment to transmission and control systems.
Note 2: JIS B 8370: Pneumatic system axiom.
CAUTION :
Operator error could result in injury or
equipment damage.
WARNING:
Operator error could result in serious
injury or loss of life.
DANGER :
In extreme conditions, there is a
possible result of serious injury or loss of life.
WARNING
1. The compatibility of pneumatic equipment is the respon-
sibility of the person who designs the pneumatic system
or decides its specifications.
Since the products specified here are used in various operating
conditions, their compatibility for the specific pneumatic system
must be based on specifications or after analysis and/or tests to
meet your specific requirements.
2. Only trained personnel should operate pneumatically
operated machinery and equipment.
Compressed air can be dangerous if an operator is unfamiliar
with it. Assembly, handling or repair of pneumatic systems should
be performed by trained and experienced operators.
3. Do not service machinery/equipment or attempt to
remove component until safety is confirmed.
1) Inspection and maintenance of machinery/equipment should
only be performed after confirmation of safe locked-out
control positions.
2) When equipment is to be removed, confirm the safety process
as mentioned above. Switch off air and electrical supplies and
exhaust all residual compressed air in the system.
3) Before machinery/equipment is re-started, ensure all safety
measures to prevent sudden movement of cylinders etc.
(Bleed air into the system gradually to create back-pressure,
i.e. incorporate a soft-start valve).
4. Contact SMC if the product is to be used in any of the
following conditions:
1) Conditions and environments beyond the given specifica-
tions, or if product is used outdoors.
2) Installations in conjunction with atomic energy, railway, air
navigation, vehicles, medical equipment, food and beverage,
recreation equipment, emergency stop circuits, press
applications, or safety equipment.
3) An application which has the possibility of having negative
effects on people, property, or animals, requiring special
safety analysis.
CAUTION
Ensure that the air supply system is filtered to 5 micron.

Installation
WARNING
Ensure all air and power supplies are ISOLATED before commencing
installation.
Do not install these valves in explosive atmospheres.
If these valves are exposed to water or oil droplets, ensure that they
are protected.
If it is intended to energise a valve for an extended period please con-
sult SMC.
If air leakage causes associated equipment to malfunction cease using
valve and inspect for cause.
Check fixings while pressure and power are applied. Initial function
and leakage tests should be performed after installation.
Only install once safety instructions have been read and understood.
