4.2.2 Mechanical Integration, Fixing Points and Connector Positions
The product must be fixed with the four fixing points located at the corners of the product. M6 screws shall be
used for the fixation of the product. The screws shall be tightened with min. 3.0 Nm (fixing screw ISO 898/1,
quality class 8.8).
NOTICE: All four specified fixing points must be used for fixing. The fixing surface should be flat to have all fixing
points connected to the surface.
The product has a membrane vent at the connector side of the product for equalizing pressure changes.
NOTICE: The vent does not require any maintenance. Any manipulations at the vent are not allowed.

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.

4.3.4 Installations at Very High Temperatures
For installations, where the product is operated close to its maximum specified ambient temperature (+55°C
<TAmbient < +70°C), it must be ensured that the natural convection is not blocked by objects close to the product.
Figure 8 Installation with blocked airflow shall be
avoided Figure 9 Installation with free airflow - good installation

RT-310 / RT-320 User Guide
Page 20 (30)
When operating the device at ambient temperatures above app. +60C it is recommended to mount the device to a
metallic base plate to improve the heat dissipation. The base plate increases the surface to spread the heat.
