Wiring
1. Avoid miswiring.
If miswired, there is a probability of damaging units or connect-
ing devices.
2. Do not wire while energizing the product.
It is likely to damage the units or connecting devices.
3. Avoid wiring the power line and high pres-
sure line in parallel.
Noise or surge produced by signal line resulting from the
power line or high pressure line could cause a malfunction.
Wiring of the reduced-wiring system and the power line or high
pressure line should be separated from each other.
4. Confirm the wiring insulation.
Inferior insulation (contact with other circuit, insulation between
terminals, etc.) will likely cause damage to the units or connect-
ing devices due to excessive voltage or the influx of current.
1. Take measures to avoid applying repeated
bending force or pulling force to the cable.
Also, pay attention not to place any heavy matter on the cable
or clipping. It is likely to cause a broken wire.
2. Confirm grounding to maintain the safety of
the reduced wiring system and for anti-noise
performance.
Grounding should be close to units and keep the grounding
distance short.

Adjustment and Operation
1. Do not short-circuit a load.
If a load is short-circuited, excessive can cause damage to the con-
nected devices. The fuse of the input unit will melt and below. The
output and SI unit will activate its overcurrent protection function.
However, they cannot cover all modes, so damage is likely to occur.
2. Do not manipulate or perform settings with
wet hands.
Performing such activity will likely cause an electrical shock.
Warning
Operating Environment
1. Do not use this product in the presence of
dust, particles, water, chemicals, and oil.
Use with such materials is likely to cause a malfunction or
breakage.
2. Do not use this product in the presence of a
magnetic field.
Use in such an environment is likely to cause a malfunction.
3. Do not use this product in an atmosphere
containing an inflammable gas, explosive
gas, or corrosive gas.
Use in such an atmosphere is likely to cause a fire, explosion,
or corrosion.
This reduced-wiring system is not explosion-proof.
4. Do not use this product in places where
there are cyclic temperature changes.
In case that the cyclic temperature is beyond normal tempera-
ture changes, the internal unit is likely to be adversely effected.
5. Do not use this product in places where
there is radiated heat around it.
Such a place is likely to cause a malfunction or breakage.
6. Do no use this product near sources that gener-
ate a surge which exceeds the benchmark test,
even though this product is CE-marked certified.
The internal circuit components are likely to deteriorate or become
damaged when there are equipment (solenoid type lifter, high fre-
quency guided furnace, motor, etc.) which generate a large surge
around the reduced-wiring system. Take measures to prevent an
electrical surge and avoid having the wires touch each other.
7. Use the product type that has an integrated-
surge absorption element when directly driv-
ing a load which generates surge voltage by
relay or solenoid valves.
8. The reduced wiring system should be installed
in places with no vibration or shock.
If installed in a place with vibration or shock, a malfunction or
breakage is likely to occur.
Warning
1. DIP switches should be set with a small
watchmaker’s screwdriver.
Caution
1. Do not disassemble, modify (including circuit
board replacement) or repair this product.
Such actions are likely to cause injuries or breakage.
2. Perform periodic inspection.
Confirm that wiring or screws are not loose.
Otherwise, unpredicted malfunction in the system composition
devices is likely to occur.
3. When an inspection is performed.
• Turn off the power supply.
• Stop the supplied fluid and discharge the fluid in the piping
and confirm the release to the atmosphere before performing
an inspection. It is likely to cause injuiries.
Warning
1. Do not wipe this product with chemicals
such as benzine or thinner.
Using such chemicals is likely to cause damage.
