Installation Environment
This product is capable for use in the environment of pollution degree 2
*1
or equivalent.
*1 Pollution Degree 2: Environment that may cause non-conductive pollution or transient conductive
pollution by frost (IEC60664-1)
1. Installation Environment
Do not use this product in the following environment
•
Location where the surrounding air temperature exceeds the range of 0 to 40
°
C
•
Location where condensation occurs due to abrupt temperature changes
•
Location where relative humidity exceeds 85%RH
•
Location exposed to corrosive gases or combustible gases
•
Location exposed to significant amount of dust, salt or iron powder
•
Location subject to direct vibration or impact
•
Location exposed to direct sunlight
•
Location where the product may come in contact with water, oil or chemical droplets
•
Environment that blocks the air vent [Refer to Installation and Noise Elimination]
When using the product in any of the locations specified below, provide a sufficient shield.
•
Location subject to electrostatic noise
•
Location where high electrical or magnetic field is present
•
Location with the mains or power lines passing nearby
2. Storage and Preservation Environment
•
Storage and preservation environment follows the installation environment. Especially in a long-term storage, consider
to avoid condensation of surrounding air.
Unless specially specified, moisture absorbency protection is not included in the package when the machine is
delivered. In the case that the machine is to be preserved in an environment where dew condensation is anticipated,
take the condensation preventive measures from outside of the entire package, or directly after opening the package.
Installation and Noise Elimination
1. Noise Elimination Grounding (Frame Ground)
2. Precautions regarding wiring method
1) Wire is to be twisted for the 24V DC power supply.
2) Separate the signal and encoder lines from the power
supply and power lines.
3. Noise Sources and Elimination
Carry out noise elimination measures for power devices on
the same power path and in the same equipment.
The following are examples of measures to eliminate noise
sources.
1) AC solenoid valves, magnet switches and relays
[Measure] Install a Surge absorber parallel with the coil.
2) DC solenoid valves, magnet switches and relays
[Measure] Install a diode parallel with the coil. Use a DC
relay with a built-in diode.
