Design/Selection
1. Use this product within the specification range.
Using beyond the specified specifications range can cause
fire, malfunction, or damage to the system.
Check the specifications before operation.
2. When using for an interlock circuit:
•
Provide a multiple interlock system which is
operated by another system (such as mechanical
protection function).
•
Perform an inspection to confirm that it is working
properly.
This may cause possible injury due to malfunction.
Warning
Mounting
4. When lifting a large size manifold solenoid valve
unit, take care to avoid causing stress to the valve
connection joint.
The connection parts of the unit may be damaged. Because
the unit may be heavy, carrying and installation should be
performed by more than one operator to avoid strain or injury.
5. When placing a manifold, mount it on a flat surface.
Torsion in the whole manifold can lead to trouble such as air
leakage or defective insulation.
Wiring
1. Check the grounding to maintain the safety of the
r e d u c e d w i r i n g s y s t e m a n d f o r a n t i - n o i s e
performance.
Provide a specific grounding as close to the unit as possible to
minimize the distance to grounding.
2. Avoid repeatedly bending or stretching the cable
and applying a heavy object or force to it.
Wiring applying repeated bending and tensile stress to the
cable can break the circuit.
3. Avoid miswiring.
If miswired, there is a danger of malfunction or damage to the
reduced wiring system.
4. Do not wire while energizing the product.
There is a danger of malfunction or damage to the reduced
wiring system or output device.
5. Avoid wiring the power line and high pressure line
in parallel.
Noise or surge produced by signal line resulting from the power
line or high pressure line could cause malfunction.Wiring of the
reduced wiring system or output device and the power line or
high pressure line should be separated from each other.
6. Check the wiring insulation.
Defective insulation (contact with other circuits, improper
insulation between terminals, etc.) may cause damage to the
reduced wiring system or output device due to excessive
voltage and current.
7. When a reduced wiring system is installed in
machinery/equipment, provide adequate protection
against noise by using noise filters, etc.
Noise in signal lines may cause malfunction.
1. When applicable to UL, use a Class 2 power supply unit
conforming to UL1310 for direct current power supply.
2. Use this product within the specified voltage range.
Using beyond the specified voltage range is likely to cause the
units and connecting devices to be damaged or to malfunction.
3. Do not install a unit in a place where it can be used
as a foothold.
Applying any excessive load such as stepping on the unit by
mistake or placing a foot on it, will cause it to break.
4. Keep the surrounding space free for maintenance.
When designing a system, take into consideration the amount
of free space needed for performing maintenance.
5. Do not remove the name plate.
Improper maintenance or incorrect use of operation manual
can cause failure and malfunction. Also, there is a risk of
losing conformity with safety standards.
1. When handling and assembling units:
•
Do not apply excessive force to the unit when
disassembling.
The connecting portions of the unit are firmly joined with
seals.
•
When joining units, take care not to get fingers
caught between units.
Injury can result.
2. Do not drop, bump, or apply excessive impact.
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 screw.
IP67 cannot be guaranteed if the screws are not tightened to
the specified torque.
