4.3 Considerations When Mounting the Device
4.3.1 General Installation Considerations
When planning an installation at least the following points shall be considered:
•
Indoor: protecting for dust (to ensure heat dissipation), vandalism, animals (rats, birds etc)
•
Outdoor: protecting for sun (to optimize ambient temperature range), dust, dirt, vandalism etc.
4.3.2 Temperature Alarms
This product has integrated temperature sensors for monitoring the internal device temperature. The limits for the
sensors are set so, that operation without alarm is ensured for ambient temperatures as specified for the product
assuming correct installation.
NOTICE: The limits have been set so that some of the components are close to the limit of the specified
temperature range. For this reason the unit shall not be operated in conditions where the temperature alarm is
activated.
4.3.3 Ambient Operating Temperature Range
This product includes a vent allowing controlled air exchange due to temperature changes. Humidity is blocked by
the vent.
To ensure correct operation over the whole specified temperature range, certain aspects need to be considered.
The limits are defined for installations with free air flow in the installation environment.
It shall be noted that in real environment:
•
Limited air flow is rising the device temperature and may lower the upper limit of the operating temperature
range
•
Conducted heat exchange through metal surfaces at the product fixing point is improving the device heat
transfer and improving the operating conditions
•
Temperature is dependent on the operational parameters, like RF output power, amount of traffic
•
This product has internal temperature sensors that will issue alarms for too high or too low temperature. The
operating conditions shall be ensured so that the normal operation does not cause temperature alarms. Any
temperature alarms shall be immediately rectified. See reference document [1] for detailed specification of the
temperature sensors alarms.
