4 Installation
4.1 Installation
Warning
•
Do not install the product unless the safety instructions have been
read and understood.
•
General instructions on installation and maintenance
Connect the valve manifold to the SI unit.
•
Assembly and disassembly of the SI unit
4.2 Replacement of the SI unit
•
Remove the M3 hexagon screws from the SI unit and release the SI
unit from the valve manifold.
•
Replace the SI unit.
•
Tighten the screws with the specified tightening torque. (0.6 N•m)
4 Installation (continued)
4.3 Assembly Precautions
•
Be sure to switch off the power.
•
Check there is no foreign matter inside the SI unit.
•
Check there is no damage and no foreign matter stuck to the gasket.
•
Be sure to tighten the screws with the specified torque.
•
If the SI unit is not assembled properly, the internal PCBs may be
damaged or liquid and/or dust may enter into the unit.
4.4 Connecting Cables
Select the appropriate cables to mate with the connectors mounted on
the SI unit.

Not used
•
The power supply for the solenoid valve and SI unit operation are
isolated. Be sure to supply power respectively.
Either single source power or two different power supplies can be
used.
NOTE
When conformity to UL is required the SI unit must be used with a
UL1310 Class 2 power supply.
The M12 connector cable for fieldbus and power supply connections
has two types, Standard M12 and SPEEDCON compatible. If both
plug and socket have SPEEDCON connectors, the cable can be
inserted and connected by turning it a 1/2 of a rotation, leading to a
reduction in man hours.
A standard connector can be connected to a SPEEDCON connector.
Warning
•
Be sure to fit a seal cap (EX9-AWTS) on any unused connectors.
Proper use of the seal cap enables the enclosure to maintain IP67
specification.
4.5 Ground Terminal
•
Connect the ground terminal to ground.
•
Individual grounding should be provided close to the product with a
short cable to assure the safety and noise resistance of the Fieldbus
system.
•
Resistance to ground should be 100 ohms or less.
4.6 Environment
Warning
•
Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
•
Do not install in a location subject to vibration or impact in excess of
the product’s specifications.
