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
No. Signal Description
1 DRAIN Drain / Shield
2 V+ Power supply + for DeviceNet
3 V- Power supply - for DeviceNet
4 CAN_H CAN_H bus line (dominant high)
5 CAN_L CAN_L bus line (dominant low)
5.2 Bus Terminator

• 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.
