1.Safety instructions

SMC CORPORATION Doc.No.EX##-OME0015

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".

To ensure safety, be sure to observe ISO, JIS and other safety practices.

CAUTION: Operator error could result in injury or equipment damage.

WARNING: Operator error could result in serious injury or loss of life.

CAUTION

Thoroughly read this manual and operate the product within the specified range. Follow the instructions. Do not drop or impart any impact to the product.

Use within specified voltage range. Use outside of specified voltage will cause malfunction, damage of unit, electric shock, and fire.

Do not touch the terminal or internal circuit board while they are energized. It may cause malfunction, damage to unit, and electric shock.

Use within operating ambient temperature. Do not use where temperature can rapidly change even thought it is within the specifications.

Foreign objects should be prevented from entering the product. Contamination by foreign objects, such as wire chips will cause fire, breakage, and malfunction.

Use within the operating environment of the protection structure. In case of IP20, avoid use in the place where water and oil scatter. To realize IP65, install manifold properly and give some prevention against splash of liguid to electrical entry.

Carry out periodical checks to confirm correct operation. Safety may not be maintained by unintentional malfunction or incorrect operation. Design must consider the space necessary for maintenance.

As the contents of this manual is sometimes changed without the previous announcement, understand them beforehand, please.

SI unit is not explosion proof. Operation in explosive enviromment may cause explosion accident.

WARNING

The product specified here is designed to be used in standard factory automation equipment. Do not use in machinery and/or equipment where operators may be injured, and malfunction or failure may cause loss of life.

Do not disassemble to repair or modify the product.

Connection

CAUTION

Power of the product and all other equipments should be turned off while wiring.

Tighten the wiring with connector and tarminal screw completely. Short circuit, fire, and malfunction will be caused if connector and tarminal screw are not tightened enough.

Avoid incorrect wiring. It may damage the product and/or other equipments. Ensure that the FG terminal is correctly grounded.

Power with correct capacity should be prepared by considering the in-rush current when starting.

Influence of noise should be avoided for the wiring. Wiring should be separated from power cables and high voltage cables. Ensure that the power is within the specified voltage range.

Ensure that the cable is capable of supporting the solenoid valve and SI unit in terms of rating.

Applicable solenoid valves

CAUTION

SMC offers no guarantee against malfunction and damage of unit when valves not described to “2-3.Applicable solenoid valve series” and loads which is not valve are connected.
