Environmental considerations cover the following topics:
•
"Temperature"
•
"Humidity"
•
"Corrosive Environment"
•
"Air Quality"
Temperature
The environment in which the MTS operates is an important consideration. The temperature should be
regulated to ensure trouble-free operation. Excessive temperatures result in generated heat that may
reduce the life-span of the electronic equipment, and could cause permanent damage.
It is recommended that the ambient temperature (at the air inlet) does not exceed 35 ºC in normal operating
conditions. For exceptional conditions, the ambient temperature must not be allowed to exceed:
•
55 ºC: MTS 2 400 MHz (without fans)
•
55 ºC: MTS 4 800 MHz
•
60 ºC: MTS 2 400 MHz (with fans)
•
60 ºC: MTS 4 400 MHz
•
60 ºC: MTS 2 800 MHz (always with fans)
The low power MTS 2 cabinet uses passive convection cooling. Fan modules may be added
where high ambient temperatures are experienced or operation at high altitude is necessary.
Keep attention that no other objects are covering the topside grilles and
leaves at least 20 cm of clearance above the cabinet(s).
Humidity
For humidity, MTS complies with ETSI norm EN300 019 1–3 Class 3.2.
At 30 ºC, the relative humidity within the site should be between 5% and 95% non-condensing.
