1 SAFETY RECOMMENDATION
1.1 General recommendation
These safety instructions are intended to prevent a hazardous situation 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
JIS B 8370 (Note2) and other safety practices.
Note 1:ISO 4414:Pneumatic fluid power - General rules relating to 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:
• The compatibility of pneumatic equipment is the responsibility 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.
• 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.
• Do not service machinery/equipment or attempt to remove component until
safety is confirmed.
Inspection and maintenance of machinery/equipment should only be performed
after confirmation of safe locked-out control positions.
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.
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
backpressure, i.e. incorporate a soft-start valve).
• Contact SMC if the product is to be used in any of the following conditions:
Conditions and environments beyond the given specifications, or if product is used
outdoors.
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.
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.
1.2 Conformity to standard
This product is certified to and complies with the following standards:
EMC Directive 89/336/EEC EN61000-6-2, EN55011, EN61000-4-5

(Note 2) Impact resistance: No malfunction resulted from the impact test using a
drop impact tester. The test was performed one time
each in the axial and right angle directions of the
main valve and armature, for both energized and
de-energized states.
Vibration resistance: No malfunction occurred in a one-sweep test between
8.3 and 2000Hz. Test was performed in the axial and
right angle directions of the main valve and armature
for both energized and de-energized states.

3.3 Electrical connection
CAUTION:
When DC power is connected to a solenoid valve equipped with light and/or surge
voltage suppressor, check for polarity indications.
For polarity indications:
1. No diode to protect polarity: if polarity connection is wrong, the diode in the
valve or switching device at control equipment or power supply may be
damaged.
2. With diode to protect polarity: if polarity connection is wrong, the valve does
not switch.
3.3.2 Cable safety instructions
1. Avoid miswiring, as this can cause malfunction, damage and fire in the unit.
2. To prevent noise and surge in signal lines, keep all wiring separate from
power lines and high voltage lines. Otherwise, this can cause a malfunction.
3. Check wiring insulation, as defective insulation can cause damage to the unit
when excessive voltage or current is applied.
4. Do not bend or pull cables repeatedly, and do not place heavy objects on
them or allow them to be pinched. This can cause broken
3.3.3 Light/Surge voltage suppressor VQC1000/2000
Indicator lights are all positioned on one side for both single solenoid and double
solenoid type valves.
For double solenoid type, 2 colors that are same as the manual override are used to
indicate the energization of A-side or B-side.
