Wiring of the signal cables
Wiring of twisted pair cable should follow the drawing shown in Fig
1. Shielding of shield cable should be one point grounding at
receiving side, or sending side. Use cable recommended by Mitsubishi
Electric Corporation.

2. Non standard wiring (mixed wiring)
Mixed wiring is available as a non-standard option. If mixed wiring is
specified, the positions of the single and double solenoids on the
manifold must be indicated when ordering.

Address setting
Power should be turned off to set address. Open the SI unit cover,
adjust by turning the address setting switch using a small bladed
screwdriver. Setting range is 1~64. As the SI unit has 2 occupied
stations, the setting will be 1,3,5...63. The address can be set
regardless of the connecting order, however it is not possible to set
with vacant positions. It is not possible to set address overlap.
Fig 1
Wiring of power supply
Ensure that the power is within the specified voltage range.
Ensure that the cable is capable of supporting the solenoid and SI unit
in terms of rating.

CAUTION
Power of the product and all other equipment should be turned off
while wiring.
Tighten the wiring with terminal screw completely. The terminal screw
for connection is M3. Use appropriate crimp-style terminal for the
terminal screw. Short circuit, fire, and malfunction will be caused if
terminal screw is not tightened enough.
Avoid incorrect wiring. It may damage the product and/or other
equipment.
Ensure that the FG terminal is correctly earthed.
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.

Operator error could result in injury or
equipment damage.
1. Standard wiring
The outputs of the SI unit are assigned from the D side (down)
solenoid valve in the order 0, 1, 2, etc.
The SI unit can be mounted from the direction of the D side or the U
side (up).

CAUTION :
Use within operating ambient temperature. Do not use where temperatures can rapidly change even though 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.
Avoid using IP20 where water or oil, etc. can be splashed. IP65 is
achieved by mounting on manifold solenoid valve and process wire
entry correctly.
Carry out regular checks to confirm correct operation. Safety may not
be maintained by unintentional malfunction or incorrect operation.
Part identification (Fig 3)
