Cooling method
(Note 1) The reference temperature measurement position is 50mm from the bottom of
the base unit.
(Note 2) Keep spare parts off high temperature and humidity to store them in a dark place
for a long period of time.
The temperature and humidity to store products for a long period of time are 0 to
40°C and 20 to 80%RH (no condensation) respectively and the temperature
variation rate should be 10°C/h or less.
Especially, as the battery and the power have an effect on the estimated usable
period when the ambient temperature is high, store them at normal temperature
(25°C) or lower.
(Note 3) Following ingredients or gas should not be contained.
Hydrogen sulfide, sulfur dioxide, chlorine gas, nitroxide (NOx), sulfur oxide (SOx),
ammonia, silicon gas, etc.
(Note 4) ・5≦f<8.4Hz ：Half amplitude 3.5mm
・8.4≦f<150Hz ：Constant acceleration 9.8m/sec
(Note 5) Grounding in other ways than the D class ground such as mesh ground is
applicable to the system under the condition where an effect equivalent to D
class ground is produced.
Users should check the effect of grounding for other grounding than D class
ground.
◆Note
Avoid installing the unified controller nv series in the following places.
・ Place where the ambient temperature exceeds the range from 0 to 55°C (The
temperature on the board gets close to the ambient temperature while it is stored.)
・ Place where the relative humidity exceeds the range from 10 to 95%
・ Place where dews are formed due to abrupt temperature change
・ Place where vibration exceeding the tolerance is applied
・ Place where shock exceeding the tolerance is applied
・ Place where corrosive gas and flammable gas (SO2, H2S) are present
・ Place containing much dust, salt and iron powder
・ Place exposed to direct sunlight
Pay attention to the following matters to install the board housing the controller
unit.
・ Install it away from the high-pressure board and power board as far as possible.
Be sure to meet the noise-resistant, vibration specifications-resistant
・ Install the storage board firmly to protect from high frequency devices and
equipment.
・ To share a channel base with other boards, check that there is no leakage current
from other boards and devices.
