4.1.4 Installation and Environment
This section describes the panel mounting method and precautions for installation.
Use environment
This section describes environment, location, and wiring precautions for the KV-D20.
■ Locations
Avoid installing the KV-D20 in the following locations:
• Locations in which the KV-D20 may be subjected to direct sunlight.
• Locations in which the ambient temperature drops below 0°C (32°F) or exceeds
50°C (122°F).
• Locations in which the relative humidity drops below 35% or exceeds 85%.
• Locations in which condensation occurs due to sudden temperature drops.
• Locations in which there are corrosive or flammable gases.
• Locations exposed to dust, salt, metal particles, or greasy fumes.
• Locations in which the KV-D20 may be directly subjected to vibration or impact.
• Locations in which water, oil, or chemicals may splash the KV-D20.
• Locations in which a strong magnetic or electric field is generated.
Install the KV-D20 as far as possible from radio transmitters and receivers.
Radio waves generated by the KV-D20 may cause noises on these devices.
■ Precautions for improving noise immunity
•
Do not install the KV-D20 inside of a panel along with high-voltage equipment.
• Install the KV-D20 as far as possible from power lines.
• If the KV-D20 is installed near equipment that generates a strong electric or
magnetic field (e.g. solenoids, choppers, etc.), install it as far as possible from the
equipment.
• Precautions for operability and maintenance
To improve safety during operation and maintenance, install the KV-D20 as far
as possible from high-voltage equipment or power equipment.
• Do not install the I/O signal lines in the same conduit as power lines or high
voltage lines. Otherwise, generated noise may cause malfunctions.
If noise causes flicker on the display of the KV-D20, provide ferrite cores on the
modular cable. (It is more effective to wrap the cable once around the ferrite
core.)
