1 Safety Instructions
These safety instructions are intended to prevent hazardous situations
and/or equipment damage. These instructions indicate the level of
potential hazard with the labels of “Caution,” “Warning” or “Danger.”
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: Manipulating industrial robots -Safety. etc.
•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 indicates a hazard with a low level of risk which, if
not avoided, could result in minor or moderate injury.
Warning indicates a hazard with a medium level of risk
which, if not avoided, could result in death or serious injury.
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.
Caution
•Provide grounding to assure the noise resistance of the Fieldbus
system.
Individual grounding should be provided close to the product using a
short cable.
•Refer to the operation manual on the SMC website (URL:
https://www.smcworld.com) for further Safety Instructions.
•Special products (-X) might have specifications different from those
shown in the specifications section. Contact SMC for specific drawings.

4 Installation
4.1 Mounting Warning
•Do not install the product unless the safety instructions have been read
and understood.
•Applicable valve series: VQ1000.
Caution
•Be sure to turn OFF the power.
•Mount the SI unit using the 4 mounting holes in the base using M4
screws. Tightening torque must be 1.3 to 1.7 N•m.
4.2 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 in excess of
the product’s specifications.
•Do not mount in a location exposed to radiant heat that would result in
temperatures in excess of the product’s specifications.
5 Wiring
5.1 Communication Connector
•Select the appropriate cable (SMC part number PCA-1557633 or
EX500-AC050-DN) to mate with the connector on the SI unit.
•The bus connector layout for DeviceNet®is as follows.
Connector: M12 5-pin plug, A-coded
Power supply + for DeviceNet®
Power supply - for DeviceNet®
CAN_H bus line (dominant high)
CAN_L bus line (dominant low)
5.2 Bus Terminator
•A bus termination resistor is required at both ends of the DeviceNet®
trunk line.
The specification of the terminating resistor is 121 Ω ±1%, 1/4 W.
5.3 Interlock connector
•The interlock connector pin allocation is as shown below.
Interlock connector: 44-pin D-sub plug connector
•Pin numbers 33 to 42 are not used (reserved).
•The power supply for solenoid valves should be supplied using the
connector pins given above.
•The power supply for the SI unit operation is isolated. Be sure to supply
power separately using the M12 5-pin communication connector.
Either single-source power supplies or two different power supplies
can be used.
5.4 Ground Connection
•Connect the product to ground using a mounting hole screw.
Individual grounding should be provided close to the product.
Resistance to ground should be 100 ohms or less.
Tightening torque for the M4 screw is 1.3 to 1.7 N•m.
