Specific Product Precautions 7
Be sure to read before handling.
Refer to front matters 58 and 59 for Safety Instructions and pages 3 to 7 for 3/4/5 Port
Solenoid Valve Precautions.
Mounting
Caution
1. Do not drop, bump, or apply excessive impact.
Otherwise, the unit can become damaged, malfunction, or fail
to function.
2. Hold the body while handling this product.
Otherwise, the unit can become damaged, malfunction, or fail
to function.
3. Observe the tightening torque range.
Tightening outside of the allowable torque range will likely
damage the product.
4. Do not install a unit in a place where it can be used as
a scaffold.
Applying any excessive load such as stepping on the unit by
mistake or placing a foot on it, will cause it to break.
Wiring
Warning
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 pressure line in
parallel.
Noise or surge produced by signal line resulting from the pow-
er line or high pressure line could cause a malfunction. Wiring
of the reduced wiring system and the power line or high pres-
sure 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 con-
necting devices due to excessive voltage or the influx of cur-
rent.
Caution
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 re-
duced wiring system and for anti-noise performance.
Grounding should be close to units and keep the grounding
distance short.

Serial Wiring EX510 Precautions
Operating Environment
Warning
1. Do not use this product in the presence of dust, partic-
les, 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 wire-reduced system is not explosion-proof.
4. Do not use this product in places where there are cy-
clic temperature changes.
In case that the cyclic temperature is beyond normal tempera-
ture changes, the internal unit is likely to be adversely effec-
ted.
5. Do not use this product in places where there is radi-
ated heat around it.
Such a place is likely to cause a malfunction or breakage.
6. Do no use this product near sources that generate a
surge which exceeds the benchmark test, even though
this product is CE-marked certified.
The internal circuit components are likely to deteriorate or be-
come damaged when there are equipment (solenoid type lifter,
high frequency 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 ab-
sorption element when directly driving a load which
generates surge voltage by relay or solenoid valves.
8. The reduced wiring system should be installed in pla-
ces with no vibration or shock.
If installed in a place with vibration or shock, a malfunction or
breakage is likely to occur.
