4.3 Considerations When Mounting the Device
4.3.1 Typical Power Consumption
• For normal operation the power consumption is app. 10 W
• The power consumption for standby operation (sending beacons, no associated client) is app. 8.5 W
4.3.2 Temperature Alarms
The 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 assuming
correct installation.
4.3.3 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.
4.3.4 Outdoor Installation with Sun Load
For installation at places where the product would be exposed to direct sunshine, user must take care that the
ambient temperature range is ensured under the sun load conditions. Direct sun load is heating the product and
therefore limiting the max ambient temperature (assumed temperature rise due to 1000 W/m2 sun load: 15°C).
There are temperature alarms built in the product alarming for too high temperatures. For more details see SW
User Guide.
A protective housing with the goal to block the sunshine could be implemented to protect the product from sun
load. The protective housing still needs to ensure air circulation around the product.
4.3.5 Ambient Operating Temperature Range
The RT-370 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 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 operation parameters, like RF output power, amount of traffic
• RT-370 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
Page 18
RT-370 User Guide
Page 18 (34)
temperature alarms shall be immediately rectified. See reference document [1] for detailed specification of the
temperature sensors alarms.
• The internal temperature alarms are adjusted so that the device supports the operating ambient temperatures
for the nominal application scenario, i.e. considering typical power consumption of 7 W
• In real environment the power consumption will be slightly lower due to the fact that there are not always trains
associated in the AP, typical real installation power consumption is in range 7..9 Watts
4.3.6 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 nearby.
Figure 8 Installation with blocked airflow shall be
avoided
Figure 9 Installation with free airflow – good
installation
Page 19
RT-370 User Guide
Page 19 (34)
When operating at ambient temperatures above app. +60C it is recommended to mount the product to a metallic
base plate to improve the heat dissipation. The base plate increases the surface to spread the heat.

4.4 Connecting the System Grounding
In the RT-370 construction, the housing is connected to the protective earth, signal ground. The RF antenna
interfaces are referenced to the GND. The 1000BASE-TX Ethernet data interface is isolated.
There are two protective earth connection points, one at the AC connector and a second one at the grounding
screw at the housing.
Figure 11 The grounding screw
Important: For a safe operation and proper p rotection against lightning, both protective earth contacts of
RT-370 must be connected to system ground. The grounding must be done always as a first step before
connecting any other external interfaces to the product
For the grounding at the M5 stud, a wire with a cross section of at least 6.0 mm2 shall be used.
Order of Installation Step Description
1. Open screw M5 nut must be opened until terminal of the protective earth can be placed at its
place
2. Install the wire The grounding wire is set below the rip-lock washer
3. Fix the nut Tighten the nut for safe operation and good reliable grounding.
The tightening torque shall be 2.0 Nm.

4.5 Connecting the RF Antenna Inte rf aces
The antenna connectors are identified with the text markings A1 (Antenna 1), A2 (Antenna 2), A3 (Antenna 3) and
A4 (Antenna 4). The product is delivered with temporary protecting caps that are removed for antenna cable
installation.
The antenna interfaces are protected against lightning with special protection devices. To ensure correct operation
of these devices it is important, that the earth grounding contact is connected to protective earth as described in
chapter 4.4 with a short cable.
The antennas might be fixed in antenna connectors directly or using antenna cables fixed to the antenna
connectors. The connectors should be secured to correct torque (typically 100Ncm, check connector manufacturer
data), specially for assemblies in vibrating environments.
