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 ambient temperature is out of the range between 0 and 55
°
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
The storage and preservation environment should comply with the same standards as those for the
installation environment.
In particular, when the machine is to be stored for a long time, pay close attention to environmental
conditions so that no condensation forms. 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 stored and
preserved in an environment where 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 electrical 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] Consider whether to attach a diode in parallel
to the coil or to use a diode built-in type.
4. Cooling Factors and Installation
Follow the specifications and dimensions shown below when you design and build a control board.
