Installation Environment
Controller
The V680-CA1D and V680-CA2D Controllers are highly reliable control devices that can withstand
harsh environments. To increase the reliability of the system and ensure full functionality, however,
install the Controller according to the instructions below.
• Installation Site
Do not install the Controller in the following locations.
• Locations exposed to ambient temperatures that are not within the range between
−
10
°
C and 55
°
C
or where there are radical temperature changes resulting in condensation
• Locations exposed to humidity that is not within a range between 35% and 85%
• Locations subject to corrosive gas, flammable gas, dust, salt, or metal powder
• Locations that will expose the Controller to direct vibration or shock
• Locations exposed to direct sunlight
• Locations exposed to water, oil, or chemicals sprays
• Mounting in Panel
The Controller can be used at an ambient temperature range between
−
10
°
C and 55
°
C. Be sure to
observe the following precautions.
• Make sure that the Controller is provided with sufficient ventilation space.
• Do not install the Controller close to heaters, transformers, or large-capacity resistors that radiate
excessive heat.
• If the ambient temperature exceeds 55
°
C, be sure to install a forced-ventilation fan or cooler to keep
the temperature below 55
°
C.
• If power lines or high-tension lines with large currents (e.g., for driving motors) are located close to
the Controller, to reduce the affect of noise be sure to test the Controller thoroughly and check the
Controller's wiring conditions.
Be sure to observe the above precautions before installing the Controller and carefully test the Controller before actual
use.
