GA90 Modular Gateway User’s Manual
-
Static inside body will result in damage too, so please wear anti-static wristband if you
have.
2.1.3
Environment Requirements
2.1.3.1
Basic Conditions
Keep the GA90 equipment in a room which has proper control of temperature and humidity, watch
out the conductivity of the shelf. Too high or too low humidity will cause short circuit or fire. At the
same time, the conductive property of rack is also considerable.
Place the equipment on a rack (if possible) which is near stable and liable power in an anti-fire,
anti-humidity, anti-dust, and anti-thief room.
2.1.3.2
Temperature, Humidity, and Illumination
Suggestions:
•
Temperature: 0 ~ 40
•
Relative humidity: 5~ 95RH without coagulation
•
Illumination: light, 500 ~750 lx, light enough for operations.
High humidity will affect the insulating efficiency of insulating materials and also cause the rust of
metals. Low humidity will make insulating gasket shrink, loose the fixed bolts, and scrape up
static. Long period of high temperature will accelerate components' aging, lower the reliability and
reduce the useful time dramatically.
2.1.3.3
Air Quality
The air particulate may enter the equipment through ventholes. Too much dust will cause
short-circuit, so the suggestion is less than 180mg/m3. In machinery room, printer and
Photocopiers shall be placed away from the power provider in case of floating particulate. Please
put it in the diagonal corner.
Keep the room clean, for the dust will cause static and bad connections between little
components
2.1.3.4
Ventilation Requirements
There are thermal discharge holes in the back and side side, so keep more than 100mm from
other stuffs for thermal discharging.
2.1.3.5
Safety
There must be some safety precautions like securities or other effective anti-thief actions. The
lightning rod is well connected to the ground, the ground bus' diameter must be more than 5mm.
For seismal zones, there must be anti-earthquake measurements, like fixed balustrade for the
rack.
